How do faulty spark plugs affect fuel consumption?

Features of the functioning of the ignition system

The ignition system is part of the vehicle's electrical equipment and directly affects the functioning of the vehicle. It must ensure the appearance of an electric spark, which at the right moment ignites the mixture of fuel and air entering the cylinders of the internal combustion engine. Failure of a part of this system will significantly change the operation of the mechanism.

Spark plugs provide an electrical discharge between the electrodes. The spark must appear in time so that fuel is not wasted. Any malfunction will affect the operation of the car. A change in the amount of gasoline consumed, the engine tripping, the appearance of strange sounds, odors, vibrations are reasons to check the condition of the device.

Ignition timing is the main parameter that demonstrates the operation of the system. The indicator characterizes the time required for a spark to ignite the compressed working mixture. If the car mechanism malfunctions, the ignition becomes late or early. Both phenomena lead to a decrease in engine power, efficiency, and efficiency. Excessive heating and increased load on engine parts are also observed.

The pressure in the fuel system differs from the calculated one

The ECU calculates fuel injection into the cylinders based on constant fuel pressure in the system. The ECU forms a mixture supersaturated with fuel at increased pressure in the fuel system, which leads to increased fuel consumption. The cause may be a simultaneous malfunction of the pressure regulators and oxygen sensor, which is extremely rare.

A decrease in fuel pressure causes the formation of a lean mixture, which affects the loss of engine power and the lack of correct response of the car to the accelerator pedal. Hyundai Solaris equipped with an automatic transmission moves in lower gears, which leads to a significant increase in fuel consumption.

The most common causes of low blood pressure are:

• clogging of the fine fuel filter;
• clogged fuel pump coarse filter (mesh under the pump suction pipe);
• significant wear of the fuel pump (the result of using low-quality fuel).

Vehicle fuel consumption when driving

The indicator is equal to the amount of fuel mixture spent, reduced to the distance traveled or in 1 hour. The volume of gasoline consumed is one of the most important characteristics of a car, changing under the influence of many elements of modern designs.

Fuel consumption depends on the following:

• fuel quality;
• vehicle operating conditions;
• driving style;
• engine efficiency;
• aerodynamics;
• weight of the mechanism;
• power consumption of additional equipment;
• system malfunction;
• timely appearance of a spark when fuel arrives;
• tire resistance.

Wheel sizes that do not match the transmission, brake pads jamming

The Hyundai Solaris transmission is designed taking into account operating conditions for wheels of a strictly defined diameter and width. The use of wheels of sizes not recommended by the manufacturer will complicate the operation of the transmission, increase road resistance and fuel consumption by 5-15%.

When the brake cylinders jam, friction occurs on the brake pads, which leads to constant braking of the car. To identify this malfunction, simply touch the outer part of the wheel rim; if it gets hot after driving, then the cause of the increased fuel consumption has been found.

Uninterrupted engine operation and low fuel consumption are some of the main requirements that owners place on their cars. Sometimes a dispute arises as to whether spark plugs affect fuel consumption or whether gasoline consumption is completely independent of their quality and condition. For an accurate answer, several factors should be taken into account.

How do spark plugs affect fuel consumption?

Suitable for the vehicle, timely replaced devices ensure a stable spark and efficient ignition of the combustible mixture. If even one fails, starting the engine will be difficult, there will be misfires, floating speed when idling, a decrease in dynamics when starting to move, or picking up speed. The gap in the spark plugs directly affects the performance of the car. You need to select according to the recommended values ​​​​corresponding to the make of the car. Typically standard values ​​are in the range of 0.5-0.9 mm.

The main problems with spark plugs are caused by the wrong choice for a particular car, or exceeding the service life recommended by the manufacturer. The latter is indicated with a small margin - the spark plug will continue to function for some time, but continued use will lead to deterioration in engine performance, excessive fuel consumption, and increased load on other parts.

Sometimes a car has problems in other systems, and the spark plugs suffer as a result of these violations. For this reason, it is necessary to pay attention to the condition of the parts until the end of the recommended service life. Replacement may be needed a little earlier. The main symptom in the absence of interruptions in operation is a change in the amount of fuel consumption.

Driver's driving style, viscosity of transmission and engine oils, use of air conditioning

When upshifting late or using air conditioning, fuel consumption increases significantly, especially on low-power engines.

From an engine operating without load (idling), partial engine power is taken off by the automobile air conditioning compressor, which increases fuel consumption by 5–15%. When driving in the city cycle, you often have to reduce speed and idle, so the increased fuel consumption of the car is especially noticeable. On the contrary, timely engagement of higher gears and rolling of the car help reduce the engine's appetite.

The use of oils with a higher viscosity than recommended by the manufacturer causes additional fuel consumption to overcome the increased resistance of the transmission and engine.

Excessive fuel consumption and faulty spark plugs

Any changes in the operation of the car or the appearance of individual parts are a reason to think about the root cause. Faulty spark plugs negatively affect gas mileage. What can be judged by the condition of the device:

• engine trouble, the car does not start - the reason is the failure of one or all spark plugs;
• black coating, darkening of the ceramic part of the part - malfunction of the injector, power unit, low quality fuel;
• uneven coating indicates the wrong choice of device for a given car;
• additives in gasoline and oil cause the appearance of tar-coke and varnish deposits;
• electrode burnout - incorrectly set ignition;
• premature wear of the electrode - low quality fuel or oil, overheating, engine detonation;
• Dry spark plugs are observed when the fuel pump motor fails, pipelines are clogged, injectors are faulty, or the coarse filter is dirty.

Automatic transmission malfunction

Modern automatic transmissions begin to operate in single-speed mode when the torque converter lockup malfunctions. Pressing the accelerator pedal will cause the engine speed to increase, but upshifting will not occur and fuel consumption will increase significantly.

The better spark plugs made of iridium and platinum

Often, consumables are made from alloys of nickel, chromium, copper, iridium, platinum, which directly affects the functioning, cost, and service life of spark plugs. It is not justified to install expensive parts on outdated car models, so when choosing a specific product you need to focus on the vehicle.

• protection of the central electrode from corrosion and high temperatures;
• service life up to 50,000 km;
• fuel economy, full engine performance;
• strong, stable spark;
• The central electrode is thin and strong.

Iridium is more expensive, but has the following advantages:

• designed for a mileage of 100,000 kilometers;
• stability of spark formation is ensured by a thinner electrode than that of platinum spark plugs;
• increased wear resistance;
• withstand high temperatures.

The use of special alloys and metals in candles

Engineering does not stand still, and today there are a variety of types of spark plugs with improved spark generation. This effect is achieved in several ways.

Firstly , they increase the spark receiving surface area: they mill or bend a groove on the side electrode or increase the number of side electrodes to 2, 3 or even 4, which ensures the reception of an electric discharge with greater productivity and significant cooling of the side electrodes during non-working cycles.

Secondly , they use electrodes made from materials that are more efficient in terms of electrical conductivity, such as platinum and iridium in the automotive industry. Platinum spark plugs have a thin electrode (less than 1 mm) completely hidden in a specially shaped insulator that has a very small nozzle, which allows you to direct a spark not just in a direct stream to the side electrode, but to create a discharge in the form of a cone, expanding towards the side electrode up to 1.5 mm.

The side electrode of such spark plugs at the point of contact is usually soldered with alloy steel alloys for greater wear resistance. Such spark plugs, under the correct operating temperature conditions, operate for at least 50 thousand km. mileage, which is significantly higher than 7-15 regular candles.

The structure of a spark plug

Even more durable are iridium spark plugs. By design, iridium spark plugs are different from all others; they have a thin, long central electrode extending several mm from the insulator, which gives a very powerful discharge to the second electrode in the forward direction. Due to the power of the voltaic arc in platinum and iridium spark plugs, self-cleaning of the electrodes is ensured, which is important when using spark plugs.

Since cleaning spark plugs is often a necessary step during operation, which is done manually using sandpaper or ultrasonic using special equipment. Such cleaning is carried out as necessary, 1-3 times during the service life of the spark plugs.

Therefore, self-cleaning is a very positive point, which is only a plus for platinum and iridium spark plugs. The power reserve when using iridium spark plugs is at least 100 thousand km, and the spark plugs become unusable not due to wear of the central electrode, as usually happens with spark plugs having a copper alloy electrode, but due to wear of the side electrode, up to before it burns out. This efficiency allows you to simply not think about replacing spark plugs for quite a long time.

Of course, platinum and iridium spark plugs have a higher cost, several times higher than the cost of regular spark plugs. But their complex of advantages, such as self-cleaning, unpretentiousness to the type of fuel and seasonal operating conditions, make them the most promising for use.

It must be remembered that incorrectly selected spark plugs will fail much faster, adding many more unpleasant moments associated with the efficient operation of the engine. To select spark plugs, you need to use the factory’s recommendations, evaluate climatic conditions, and plan your own wallet.

Advice for car enthusiasts on fuel consumption

Following simple recommendations will help you avoid excessive consumption of fuel and keep your vehicle's systems and spare parts in good condition for a long time. Basic tips:

1. A variety suitable for the car, timely replacement of spark plugs.
2. Purchasing high-quality fuel that matches the vehicle brand.
3. Changing your driving style to a smoother, more gentle one.
4. Avoiding frequent, prolonged travel at low speeds, such as traffic jams.
5. The appearance of soot and damage is a reason for premature replacement of the device.
6. Timely maintenance is the best preventive measure.

Conventional spark plugs require replacement after 30,000-50,000 km, improved spark plugs - 90,000 km. Sometimes the procedure needs to be performed earlier than the time specified in the instructions. The main prerequisites are excessive fuel consumption, problems with engine operation, and changes in the appearance of the spark plugs. When the device is worn out, skips occur, reducing the performance of the motor, leading to an increase in the load of other parts and systems of the machine

Answer: Gasoline consumption increased after replacing spark plugs

I support: turn out the spark plugs and take a look. If gasoline consumption immediately after replacing the spark plugs increased by 50%, some cylinder is probably simply not working. Maybe the coil is covered, maybe there is no contact somewhere. Maybe they simply forgot to put the connector on the coil. Maybe the spark plugs are fake: the Chinese love to make fake NGKs. Three work, one doesn’t, that’s the result.

Or, as an option: maybe all four work intermittently. But it’s less likely: then the engine would be shaking, it’s hard not to notice. And if one cylinder does not work, Japanese engines are so well balanced that you almost don’t feel it. So turn out the spark plugs: everything will be visible from the soot.

I will report the results of the inspection. All cylinders work. Installed old spark plugs. Along the way, oil was discovered in the well of one of the spark plugs; it looked like the cylinder head cover gasket was leaking. It is possible that the presence of oil on the spark plug caused the spark plug to periodically fail to fire.

Added after 7 minutes

Vacuum hose – Concern Level: 7

This is because the compression was normal and the color of the thread was different in no way because of this; then, the injectors are in order, otherwise the picture on clean, unmarked spark plugs should have been consistent. The insidiousness of the situation is that worn spark plugs may not arouse suspicion for a very long time either on the part of the self-diagnosis systems or on the part of the owner. The computer considers the number of interruptions acceptable, by ear the engine runs smoothly, and consumption is creeping up.

Do spark plugs affect fuel consumption?

Many of those who purchased a car not so long ago do not understand whether spark plugs affect fuel consumption. Therefore, they strive to exhaust the life of the spark plugs to the end and save on replacing them as long as they still somehow react to an attempt to ignite.

However, this does more harm than good, and first of all it has a strong impact on fuel consumption, although over time, individual parts of the engine mechanism begin to suffer.

1. Why you can't save on candles
2. How old spark plugs can affect the daily use of a car
3. Computer malfunctions
4. High one-time fuel consumption
5. How to understand that it’s time to change spark plugs
6. How to choose replacement spark plugs

Gap size • What is the norm

The relationship between spark plugs and fuel consumption • If 2 spark plugs do not work, you can see and hear it.

Why you can't save on candles

Each candle has three stages of operation:

• Ideal. In this case, a spark is produced the first time you try to start the car, and the computer does not detect problems with operation.
• Compliant with standards. Sometimes the spark does not appear after the first time, but this is an infrequent problem. The car's computer takes it into account when creating the air-fuel mixture.
• Not up to standard. The spark plugs often fail and do not produce a spark, the number of errors multiplies - and all this has a bad effect on fuel consumption.

The problem arises due to the fact that the air-fuel mixture either does not ignite at all or does not burn out completely, which means that in order to create more traction, the driver has to press the gas harder and supply more fuel. Overspending can reach 5%.

At first glance, it seems that this is quite a bit, but given fuel prices, the bill runs into tens of thousands of rubles. So the answer to the question of whether spark plugs affect fuel consumption is unequivocal: yes.

Ultimately, the costs can be so high that it would be cheaper to buy several sets of even expensive iridium replacement spark plugs.

Injector and its cleanliness

Injector cleanliness is another factor that can affect fuel consumption. It needs to be cleaned every 10 thousand kilometers. In this case, use ultrasonic cleaning, it is 4 times more expensive, but much more effective than standard washing.

Many real drivers claim that ultrasound is harmful to the car, but qualified technicians unanimously say that this is a lie.

Since regular cleaning is done almost blindly - a simple external washing of the injector. But its analysis and careful exposure of each part to ultrasound is very effective, although the car may be “capricious” for the first three days, and this depends on what liquid the injector was washed with, oddly enough, but domestic products are better in this case.

How old spark plugs can affect the daily use of a car

Constant excessive fuel consumption caused by the use of old spark plugs can not only seriously hit the car owner's pocket. Other problems may arise.

Computer malfunctions

The vehicle's on-board computer continuously records fuel consumption and ignition errors. Based on this, it forms an air-fuel mixture adequate to the situation.

However, if old spark plugs often fail and do not allow you to correctly estimate fuel consumption, the computer often makes mistakes in its calculations and creates a mixture with incorrect proportions. This causes even more errors and problems in the car, and in trying to correct them, the computer moves further and further from the correct circuits.

If this situation continues on a regular basis, the computer's algorithms begin to fail, and their debugging can be even more expensive than all the fuel losses before. So it’s clear whether replacing spark plugs affects fuel consumption and the general condition of the car - it has a very strong effect.

High one-time fuel consumption

Most often, this problem arises in situations when the driver presses the gas to the floor, for example, when overtaking.

Since until now the car already required an increased supply of fuel to achieve the desired thrust, in such circumstances, when additional assistance is required, it can begin to burn at a high rate. There is another option - the engine will simply start idling at the most inopportune moment. This is fraught with emergency situations on the road.

We get to the node: we carry out diagnostics and change the spark plugs

It is recommended to start any work under the hood by disconnecting the battery. It is not necessary to remove it, if it does not interfere, just disconnect the terminals. Then unscrew the lid, this is on Solaris, the insides of other cars may look different. Under the cover you need to unscrew 4 coils. Unscrewed - remove them and get to the spark plugs. Using your head, unscrew 4 candles. Through the holes under the spark plugs, using an endoscope, we evaluate the condition of the pistons. As you would expect, the candles look deplorable, there is carbon deposits on them and there is a slight deformation - visually.

At this point, local experts - neighboring car enthusiasts - stepped up: looking at the smoked candles, they sprinkled them with practical advice. The point of the advice was that you don’t have to spend money on new spare parts, just soak the old ones in some solution so that they become as good as new. I didn’t remember the recipe for the solution, although at my son’s request I soaked experimental parts in it. The blackness was removed from the candles, but it was of little use. The machine refused to work normally, despite the carefully carried out procedure. The newly minted mechanic had to go to the store for new ones, since the result of the experiment turned out to be zero - he only lost time.

Replacing the spark plugs and flushing the fuel line had a positive effect. I don’t know how drivers evaluate the agility of their “iron horses,” but my son stated a fact - the car ran “more cheerfully” and fuel consumption returned to previous norms. Draw your own conclusions.

A Hyundai Solaris car may begin to consume more and more fuel over time, and sometimes there is a sharp increase in consumption. Eliminating the cause will help restore optimal fuel consumption and avoid failure of vehicle components and assemblies, so you should not delay in resolving this issue.

Not all Hyundai Solaris owners can identify the reasons for increased fuel consumption and are forced to contact specialized auto repair shops. The excess consumption is almost certainly due to one of the following reasons:

1. the electronic control system of the Solaris engine is faulty;
2. the fuel pressure in the fuel system differs from the calculated one;
3. incorrect shape of the fuel torch generated by the injector;
4. the air filter is clogged;
5. the car's automatic transmission is faulty;
6. driver's driving style, viscosity of oils used, use of air conditioning;
7. installation of wheels that do not match the transmission, jamming of brake pads.

How to understand that it’s time to change spark plugs

Often, problems with spark plugs are completely unnoticeable until a certain critical moment occurs: the computer does not provide information about any malfunctions that occur, the engine, at first glance, works as always, and consumption increases so imperceptibly that the owner does not immediately pay attention to it.

This is a particularly dangerous situation - it is because of it that accidents most often occur and the internal mechanisms of the car deteriorate. If it is not clear whether spark plugs affect a car’s fuel consumption, you need to monitor this point yourself, without waiting until everything becomes obvious in an extreme situation.

Tools needed to get to the node

No special devices were required for diagnostics and replacement of spark plugs. We managed on our own: “heads” and keys of different sizes were available. To view the pistons, an inexpensive Chinese-made endoscope was useful, which works by connecting to a smartphone. It is an “eye” – a camera on a wire connected to the phone. On the screen you can see everything that the “eye” sees.

How to choose replacement spark plugs

The ideal option is to use those recommended by the manufacturer for a specific car model. If this is not possible, you should look for analogues on the Internet in advance, paying attention to all the features:

• thread length;
• diameter;
• compatibility with a specific machine.

Inexperienced sellers often recommend “similar” candles, which, in fact, do not meet all the characteristics. They will not work very well and will quickly deteriorate, so you need to be more careful about such moments.

Plugs that are too “cold” will soon become dirty, and plugs that are too “hot” can even damage the engine itself.

Iridium spark plugs are more profitable, although such a set is more expensive. But they require replacement almost three times less often than usual and work more reliably. They also allow you to reduce fuel consumption.

It is especially useful to take iridium kits for older engines, which themselves are prone to failure - such spark plugs will help reduce the number of unpleasant moments to a minimum. However, it is important to use them with good fuel, otherwise they quickly deteriorate and cease to differ in their properties from ordinary ones.

You should not use any non-standard options - as a rule, they do no good to a regular motor, and such spark plugs have no special advantages.

The appearance of soot and dark plaque

A much more common malfunction is black spark plugs, which is associated with darkening of the ceramic coating by combustion and fuel processing products. This can be caused by any change in the operation of the power unit, a faulty injector or low-quality fuel. Quite often, only one spark plug from the entire row darkens, and the reason for this may be in it itself, and not necessarily in the operation of the elements of the piston group. This may be due to the wire or tip not working.

The deposit may be applied unevenly, which indicates that the spark plug does not match the specific markings of the car engine. For example, if the heat value is higher than the permissible value, then the top of the candle will turn black, while its body will retain a snow-white hue. Their darkening can also be affected by ignition that is too late. In the case of a faulty injector, a similar effect also occurs, which is associated with the working mixture being too rich. Thus, if after replacing the spark plugs your fuel consumption increases, check how well they match the engine of your car.

As you can see, any problem can and should be diagnosed. The sooner this is done, the sooner it will be possible to understand why the car began to “eat” more gasoline or diesel fuel, and whether the spark plugs are to blame. See you in new publications and articles! Have a good day!

How spark plugs affect fuel consumption or why it is necessary to monitor the ignition system

What is an internal combustion engine? And how versatile is it? It turns out that starting the engine is complicated by the “cold” temperature regime, which makes it difficult to form high-quality and consistent mixtures, as well as reliable and rapid ignition, the necessary and absolute combustion of the air-fuel mixture. Understanding the principles of engine operation, it is very easy to understand how spark plugs affect gasoline consumption, and whether it is possible to influence this, trying to reduce spending on the family budget.

Internal combustion engine

Let us recall that the working mixture itself consists of fuel, air and exhaust gases that accumulated in the cylinder during the previous operating cycle. Gasoline engines have a special source of necessary heat, without which it is simply impossible to imagine the combustion of the working mixture in the cylinders and the desired start of the vehicle. This source is the spark plug spark.

Signs by which you can determine the oil content of a car engine

When buying a used car, the buyer often asks the seller the following question: “Does the engine burn oil?”

Some of the sellers answer honestly, and some, if this problem is present, hide the answer in order to quickly get rid of the car. Well, it’s understandable who would buy a car that will require repairs in the near future.

Maslozhor

in auto mechanic slang, this is increased consumption of motor oil in an internal combustion engine.

There are five visual cues,

by which you can determine whether a car’s engine consumes more oil than normal or whether this is inherent in its design features.

Let's tell you about each sign of "oil glutton"

using the example of “Zhigulevsky”

a motor whose oil consumption is approximately
one liter
per
500 kilometers
.

Definition by exhaust.

It doesn’t matter whether the car’s exhaust system has a built-in catalyst or not, the oil that gets into the combustion chamber during engine operation does not burn completely and, together with the exhaust gases, enters the exhaust system. On cars where the engine “eats”

oil, the exhaust pipe of the muffler is covered with a black oily coating.

Determination by oil.

Black engine oil on dipstick

may indicate not only that it contains good detergent additives, but also that the engine is “consuming” oil. Now I’m talking about the extremely black color of the oil, which has the smell of exhaust gases,

in this case, we can say with confidence that the engine consumes more oil than normal.

Features of the functioning of the ignition system

• One basic physical principle has been introduced into the ignition system, which allows us to understand how spark plugs affect fuel consumption. Let us recall that in the process of operation of the entire system, electrical energy is converted into that very movable energy - thermal. This process starts due to the resulting discharge between the electrodes in the spark plugs.
• According to technical documents, it is known that for normal operation of the engine and combustion of the working mixture in the cylinders, an electrical discharge voltage of at least 10 kV is required. And with an increase in this number, the gap between the sparks of the electrodes increases. It cannot be said that this has a positive effect on the ignition system; all devices and components are under load, and the car owner calculates the cost of gasoline, increasing the number of refills. Here is the first answer to how spark plugs affect gasoline consumption and why there are malfunctions in the system.
• It is believed that not only the power of the electric charge, but also the time intervals between ignition of the working mixture are of great importance. They practically affect the operation of the engine, its starting and maneuvering features. The optimal operating option is manifested in the interaction of several components and even technical parameters are indicated. Let us remind you that at the moment of ignition of a special air-fuel mixture, the pressure in the system reaches its maximum. And when the piston passes top dead center, it is at an angle of 10 degrees to the angle of rotation of the crankshaft. And only if all technical parameters coincide, we can say that the engine runs smoothly, and there is no need to think about how spark plugs affect fuel consumption.
• There is a proportional relationship between the ignition moment of the working air-fuel mixture, as well as the combustion rate and the speed characteristics of the engine.

Thus, the operation of the internal combustion engine is associated with peculiarities, as well as the consistency of the operation of all components of the ignition system. All the subtleties of operation are difficult to take into account and understand, but if the ignition system malfunctions inside, it provokes a disruption in the operation of other systems, which means that the question of how spark plugs affect gasoline consumption becomes relevant, and whether something can be changed.

Filtration system

“Hello Sergey and all readers of the site avto-blogger.ru, I would immediately like to say thank you especially for your answers to the readers. So I decided to ask you a question about my VAZ 2114. I have a LUX version with an on-board computer. Lately I have noticed that my fuel consumption has increased. If earlier, about six months ago, the consumption was 7.5 - 8 liters in the city, now, according to the on-board driver, it’s 9.5 - 10.5 liters, although I also drive on the same road to work, and it’s not winter yet! How can we explain this fuel consumption? I noticed that the consumption began to increase after a trip to the south, 1700 there and 1700 back, about 3500 kilometers, maybe the fuel is not of good quality, is something clogged in me? In the morning I noticed that the engine was knocking a little (troiting), could the consumption be related to this? Please give me some advice Sergey, the fuel consumption is just scary lately! I'm waiting for your answer, Arthur."

How do spark plugs affect fuel consumption?

The operation of vehicle mechanisms depends on many components. And the driver is not always interested in tuning, the “stuffing” of the car’s interior; many people wonder how much it will cost to maintain the car. Presumably, the owner estimates the costs of repairs, technical inspections, as well as refueling. And if there is an overspending of finances, then the desire to understand how spark plugs affect gasoline consumption is immediately revived. And we can voice some of the reasons for the financial losses of the owner of the “glutton” car.

1. Bad gasoline. The main reason for overspending of a car owner's money. If you want to save on the quality of fuel, then you will lose on the quantity of gasoline purchased. If you think about how spark plugs affect fuel consumption, you can remember what the mixture is formed from in the cylinders. And the combustion rate of the working air-fuel mixture also depends on the composition and homogeneity of gasoline, the degree of compression and other factors affecting mixture formation.
2. Condition of the candle. The main components of the spark plug - the central electrode, the insulator with the housing, and the ground electrode - must be in good working order and undamaged. After all, a spark jumps between the central electrode and the ground electrode, which ignites the working mixture. If the spark plug is new and in good working order, then the engine starts without problems, and its operation at idle and at maximum speeds does not suffer.

Selecting spark plugs based on material for making electrodes

To understand the effect of a spark plug on excessive fuel consumption, you should look a little more closely at its design. It consists of an insulator with ribs, a contact terminal, electrodes and an O-ring. Everyone has heard that there is such a thing as spark plug gap. In practice, this is precisely the distance that exists between the side and central electrodes. It is between the two of them that the spark occurs, which is required to ignite the working mixture. Now let’s try to identify the symptoms indicating a malfunction in the spark plugs:

Features of spark plugs

• The temperature of the central electrode of the spark plug reaches 850 degrees Celsius.
• Electrode material is chromium steel wire or nickel-manganese.
• The product has high temperature resistance and a low expansion coefficient.
• The gap between the electrodes according to the standard is 0.5-0.9 mm.
• The performance of a candle depends on its thermal state.

Thus, in the design features of the product, you can find some features to understand how spark plugs affect gasoline consumption, and whether this can be corrected.

Advice for car enthusiasts on fuel consumption

1. It is not recommended to frequently change the brand of gasoline or supplier. The condition of the working mixture, and how susceptible it can be to combustion and the release of thermal energy, depends on your constancy and devotion to the gas station.
2. Monitor the external condition of the spark plugs; they should not be damaged or covered with soot, otherwise you will have to think about how the spark plugs affect gasoline consumption. It should be remembered that after starting the engine, the tip of the spark plug insulator must warm up to the self-cleaning temperature, which is approximately 400-500 degrees Celsius. If the condition is met, then carbon deposits do not form on the spark plug body, which means that the machine works well and confidently.
3. We remind you that if you often travel at low speeds, for example, in traffic jams, this leads to more intense carbon formation, and this leads to increased financial costs, and the question of how spark plugs affect gasoline consumption comes up more and more often.

Vehicle fuel consumption when driving

Thus, if you keep your car in good condition, check the ignition system, and periodically change spark plugs, you can save on refueling by spending money on more valuable things. It is worth following all the rules for operating a vehicle and carrying out technical inspections in order to decide in time how spark plugs affect gasoline consumption.

And if you have a recipe for saving gasoline and can prove that spark plugs affect fuel consumption, then write to us and we will discuss all your opinions.

The goal of our joint work is to help car enthusiasts who are trying to solve the problems of their steel horse on their own.

What is normal oil waste • Ignition coils

1. Incorrectly selected or simply low-quality (fake) oil . It is necessary to fill the engine with oil with the viscosity and tolerances recommended by the car manufacturer. And try not to buy oils from dubious brands and untrustworthy retail outlets.
2. Harsh engine operation . In particular, frequent operation at high speeds. At the same time, its temperature rises significantly, and more oil is needed for lubrication and cooling. Remember that more oil is consumed in the cold season. This is due to the peculiarities of crankcase ventilation. Therefore, to reduce waste, try to warm up the car at idle in winter!
