How to make fire from a car exhaust pipe?

Author: Evgeny Zhivoglyadov. Publication date: September 19, 2022. Category: Automotive equipment.

If a flame bursts out of the exhaust pipe of a car driving nearby, then there are two options for why this is happening: the vehicle is faulty and needs to be abandoned urgently, or the car enthusiast has seen enough films with beautiful cars and decided to become the owner of a “high-power racing unit.” The second option is much more common. The desire to attract the attention of others pushes car owners to create tuning, which is called “dragon language”.

It’s worth saying right away that this is a purely visual effect, which in no way indicates the power and capabilities of the machine. This is just a spectacle, lasting a few seconds and nothing more. To be completely honest, such tuning not only does not bring any benefit, but also completely harms the car and can be extremely dangerous for the life of the driver himself. But, if the desire to get a “tongue” of flame is irresistible, then you need to do everything correctly and understand all the intricacies of recreating such styling.

Flame emitted from the muffler

Fire from the exhaust pipe happens in two cases: either in case of some malfunctions that should be fixed immediately, or to demonstrate your car. The flame rushing out, or, in other words, the “tongue of the dragon” is a spectacle that guarantees everyone's attention, causing a lot of emotions. It gives the impression of being powerful, sophisticated and cool like a racing car. This effect does not indicate the power of the engine at all, but it leaves vivid emotions and is undoubtedly suitable for any kind of show or simply for those who like to stand out. Racing cars have a completely short and straight exhaust system, which is not able to completely extinguish the burning gases, which contributes to the appearance of flames. In ordinary cars, the design of the exhaust system is somewhat different, and besides being spectacular and entertaining, the “dragon tongue” does not bring any benefit; on the contrary, the frequent use of a bursting flame harms the car.

By taking all precautions, you can achieve such an impressive effect yourself, that is, make a “monster” out of your car with your own hands by installing a homemade special device that ignites the remaining gasoline at the outlet of the exhaust pipe, or you can purchase and install an electronic system. If you do not know how to handle electronics, it is better to have it done by a professional.

Before installing the equipment, do not be lazy to diagnose the fuel and exhaust systems; the car’s power supply must be intact and in good working order.

To install the system, the following conditions are required:

gasoline engine (carburetor or injection);
straight-through muffler;
lack of exhaust gas neutralizers.

Curious incidents with fire cars

Installing your own fiery exhaust on a car is an opportunity to make the car start challenging and daring. But don't forget about safety. There are those who want to save on installing a flame exhaust and do it themselves, without even basic skills and knowledge. It's good if everything is installed correctly.

But accidents often occur when car bumpers or tires catch fire. Only after this does the realization come that it was not worth saving on installing the system. When a car catches fire from a fire in the muffler, you may panic and think that if you drive faster, the flame will immediately go out. But in practice, the flame only burns hotter.

The simplest scheme to achieve the “dragon tongue” effect

Making fire from a muffler is quite simple. When the car is working properly, the exhaust gases cool down as they pass through the exhaust pipes, which means there is nowhere for the fire to appear, so a special spark plug is installed at the end of the exhaust pipe, which ignites a small portion of the gasoline that is not burned in the cylinders.

In order for the spark plug to work and create a spark, it must be connected to a simple pulse generator. Using a switch (button) located in the car's interior, the spark plugs are turned off so that not all the fuel in the cylinders burns and some of it ends up in the exhaust pipe. The pulse generator starts, supplying a spark to the additionally installed spark plug. The effect is ready, flames burst out from the exhaust pipe.

To avoid an explosion or failure of the exhaust system, when using manual gasoline supply, the main thing is not to overdo it so that too much of it gets there.

Safety precautions

Anyone who undertakes tuning the exhaust system must be aware that any manipulations with fuel are extremely dangerous. Any mistake is highly likely to cause an explosion. Therefore, such experiments are not recommended for those who do not have the necessary knowledge and skills.

Finally, here are some tips for those who decide to remake their car - perhaps they will help you save your life and health:

Do not put too much fuel into the exhaust system - this may cause an explosion;
The effect of flames from the exhaust pipe is not allowed if the car is moving - you can surprise others only during deceleration;
Carefully ensure that fuel is injected into the exhaust system without leaks - this will lead to an explosion;
Demonstration of the effect is permitted only outdoors and only at those moments when there are no people or animals in the immediate vicinity;
The duration of the effect can be no more than two to three seconds;
It is strictly forbidden to turn on the effect while driving on highways and public roads - this can lead to serious accidents.

If you look at it, by and large, this effect can be demonstrated to friends or spectators before the start of a car race. In this regard, it is worth considering whether it is worth spending precious time and money, putting your life and car at risk for the sake of a few seconds of delight from your friends or spectators in the stands.

How to put such a scheme into action?

To install an additional spark plug in the muffler (in the last pipe of the exhaust system, after the resonator):

a hole is made to secure the spark plug bushing using cold welding;
the spark plug is screwed in;
put on the spark plug cap.

Nearby there is a mount for the ignition coil (high-voltage transformer). The coil must be independent, turned on with a separate button. All elements are connected with a special wire.

To prevent some of the gasoline from getting into the working cylinders, but into the exhaust pipe, you should unscrew one or two spark plugs and put a plug in their place. After the demonstration is completed, the candles are put back.

The aroma of a burning fireplace

Visualization of the burning flames is the main, most labor-intensive and expensive part of the construction of a false fireplace. But the feeling of warmth and comfort will be incomplete without the specific smell of burning wood.

Achieving this effect is not difficult. You can choose a suitable option from oriental incense. There is a chance to get a more realistic smell from the combustion of thin splinters, but in this case you need to take care of fire safety.

If you have set yourself the goal of getting the most realistic artificial fireplace for yourself, then it is better to hide the combustion chamber under the outer panel of the fireplace in a closed niche. It must be equipped with forced ventilation based on a computer fan with the odor escaping into the hearth of the fireplace.

Connecting an additional transformer

For safety reasons, the battery is disconnected before laying the wire.

Additionally, three wires with a cross-section similar to the wires going to the installed transformer are tightened.

From a conventional ignition coil, one wire goes to an additionally installed terminal, the second is laid to the car’s dashboard, the third connects the dashboard to the new transformer.

Next, a toggle switch is installed on the dashboard, to which pre-prepared wires will be connected.

To avoid engine imbalance and increased wear of piston system parts, the device should be used correctly:

engine starting;
warming up the engine to operating temperature;
engine speed should reach 3500 rpm;
pressing the system power button for 2–3 seconds.

To prevent the engine from stalling, turn on the ignition key when reducing speed.

Precautionary measures

It is recommended to proceed with extreme caution when installing the system. There is a high risk of compromising the integrity of the exhaust system. It is necessary to carefully control the amount of freely flowing gasoline to avoid the occurrence of an explosive situation. Also, to ensure the safety of all engine parts and the exhaust system, it is necessary to comply with the time limits: the flame should not go out for more than three seconds.

Displaying special effects with fire is permissible only in a free and open area, away from people and various objects that could ignite. The car must be immobilized when performing such a stunt. The appearance of “dragon tongue” on public roads is strictly unacceptable.

The flame can be about half a meter, this can damage the paintwork of the car. The simpler the flame production system is, the more damage is done to the car. Therefore, it is better to give preference to the electronic version. When performing “flames”, you should not get carried away and perform the trick often in order to avoid car damage. Always follow safety precautions, then the fire show will bring only positive emotions.

Where is it used?

As mentioned earlier, most often such a pyrotechnic show is used during various automoto shows, car festivals and car enthusiasts' gatherings. In some cases, a similar effect is also used in circus performances.

It is not often seen in everyday life. Firstly, the vehicle must be specially converted for these purposes. Secondly, this is not entirely dangerous and can only be done with a full list of safety measures. And finally, thirdly, the increased thermal load more sharply reduces the service life of the exhaust pipe and other elements that are connected to it.

Physics of the process

Now we will try to answer the question: “How to make a flame from a muffler?” The basis of any such special effect is the combustion process. For its physical implementation, 3 components are required:

Availability of the required amount of oxygen
Availability of fuel
Presence of ignition source

What methods should I use?

There are situations when, due to the large area of damage, it will not be possible to apply the methods discussed above. In such a situation, it is necessary to remove the muffler and find a good welder.

Using an angle grinder, a metal patch 1 mm thick is cut out, after which the workpiece is welded onto the damaged area in such a way as to ensure that the damage is covered.

If desired, you can examine the internal elements of the muffler and assess their condition.

If necessary, the body is cut into two halves, and then an opening is made for inspection and repair of partitions and pipes.

Before starting restoration work, it is advisable to degrease the damaged area and treat it with high-temperature paint (more on this below).

Shots on injection engines

Basically, this problem occurs quite rarely on injection-type engines. Even if such a malfunction occurs, then, as a rule, the reason may be hidden behind the same reasons as in a carburetor engine. The only exception to the rule may be a malfunction of the sensor contacts. This is what sometimes occurs on injection engines more than other cases. It is almost impossible to independently identify such a problem. Therefore, immediately when popping noises appear from the muffler, it is reasonable for the owner of a car with an injection engine to seek help from specialists. Only diagnostics will allow you to accurately determine the problem.

The video will explain why popping noises occur from the muffler:

Extraneous sounds in the muffler are a clear sign of a malfunction in one or more engine systems. Let's look at why the muffler shoots and what driving with such a malfunction can lead to, as well as how to independently diagnose the cause. To understand why shots occur in a silencer, you should start from the very basics.

Steel chimney

Chimneys made of steel have extremely high thermal conductivity. As a result, there is no need to heat such a chimney for a long time. It heats up quickly and without much hassle. Also, its advantages include its low cost and the smoothness of the internal surface of the chimney. There is practically nothing for soot and flammable sediments to cling to on the inner surface.

However, studies have shown that the smooth surface of chimneys does not always have a positive effect on the performance of steel chimneys and fire safety. What we have? We often have the problem of overheating of steel chimneys. So what is the reason why traces of fires are so often visible on the roofs of buildings?

If the chimney is designed correctly, then problems at the floor level should not arise. A steel chimney is a source of fire hazard if it is not used for its intended purpose, the steel has insufficient heat resistance or combustion products burn out as they exit the pipe.

Aggregate method

Recently, the aggregate method has become increasingly widespread, which consists of installing additional equipment that allows the engine to warm up under standard conditions. In other words, to achieve the goal, there is no need to resort to any significant additional manipulations.

Modern manufacturers offer a wide variety of devices to heat the oil. However, despite the independent technical solutions, they all have one common operating principle and a single device, which consists in the use of electrical energy and a special heating element mounted in the engine crankcase.

The heating element (heating element) is located in the crankcase in such a way as to be constantly immersed in engine oil. Otherwise, the heating element will quickly fail. If necessary (lower temperature), before directly starting the engine, a direct or alternating electric current (12, 24 or 220 V) is supplied to the heating element, which helps warm up the oil and normal engine starting.

As a rule, heating elements have one drawback associated with the uncontrollability of the heating process. The temperature of the oil in the crankcase can reach a critical point and it will boil. This can be avoided by using a special thermostat, which is used in conjunction with a heating element to turn it off when the required temperature is reached. Some modern heating elements have a self-regulating operating algorithm, eliminating the need to use a thermostat.

Decorative firewood for the fireplace

In specialized salons you can find an abundance of options for such products; quite realistic firewood with a natural log pattern is available for sale. They can be plastic or ceramic. Any imitation, purchased or made independently, is intended to add realism to a decorative fireplace in order to help you feel all the splendor: home comfort, harmony, tranquility and warmth.

Imitation of plastic firewood or coals, has a fairly simple operating principle.

Coal and firewood are illuminated with red lighting. The light bulb can be located inside the firewood. Of course, this is not so reliable, but still. More expensive electric fireplaces are characterized by flickering or a picture of artificially transmitted tongues of fantastic flame. It is possible due to a special mechanism in which special elements rotate around the lamp, alternating with transparent and shaded areas. Such lighting can be located either behind the fake logs, or in the inner part.

Exactly the same lighting system can be used to achieve the effect of fire, using natural coal, which should be placed in the niche of a false fireplace. In this case, the backlight should be placed from the bottom.

Conclusion

The effect, also called the dragon's tongue, which consists of the appearance of a flame behind the car, is decorative and is suitable for demonstration at all kinds of shows or festivals and other festive events. A similar phenomenon occurs due to incomplete combustion of gasoline in the engine cylinders and its subsequent ignition in the exhaust system. As an entertainment effect, this is quite acceptable if certain safety requirements are met, but you should not get too carried away with it. Its prolonged and frequent demonstration can lead to damage to the engine and the vehicle as a whole. » alt=»»>

Christmas garlands

Preparing branches All people love the New Year. Therefore, every person has more than one Christmas tree garland in their home. But few people know that with its help you can easily and quickly make an artificial fire in a decorative fireplace with your own hands. Therefore, this method is considered one of the simplest and most effective. Moreover, anyone can handle it, and the cost is very low. To make the flame look like a real one, you will need the following materials:

tree branches of various sizes;
aluminium foil;
lace. It can be easily cut from an old dress;
stones (several pieces);
glue;
Christmas tree garland with a background color of red, orange or yellow. The best solution would be to use a flickering garland.

The simulation structure is assembled as follows:

wrap the branches with foil without gaps;
coat the lace with glue and attach it to the branches. Next, wait until they are completely dry;

Note! It will take about a day for it to dry completely.

Next, you should carefully cut the lace case and remove the blanks from them;
after that, in the hearth of stones, we lay out the stones in a circle;
We place a garland in the middle of the resulting circle, and bring the cord and plug out;
We place the resulting “lace” firewood in the manner of a fire.

Stages of forming a fire: Plug in the garland and enjoy the imitation of fire! As you can see, this method is very easy to implement and will cost you much less than all other methods.

Candles and romance

The simplest, but also the most dangerous, way to create the illusion of fire in a decorative fireplace is to use ordinary lit candles.

Candles in the fireplace

But here it should be remembered that the fireplace should be sheathed with plasterboard sheets with fire-resistant properties. This will minimize the risk of fire. Among other things, the candles will smoke, which makes this method less popular than all of the above. This method is considered one of the design solutions to make the room romantic and fabulous. In this situation, candles can be placed individually around the perimeter of the hearth, or installed on a low candelabra. As you can see, simulating a flame in a decorative fireplace with your own hands is possible in a variety of ways. All you have to do is choose the most suitable option for yourself, implement it correctly (if it is complex in execution) and enjoy the decorative fireplace even in your apartment.

Some useful theory

After fuel enters the combustion chamber, the ignition process occurs, the piston performs a power stroke, after which the combustion products go into the exhaust manifold, bypass the resonator and are thrown out through the exhaust pipe. For a flame to appear from the muffler, a small portion of the fuel must be unprocessed and untouched.

Together with the products of fuel combustion, it reaches the outlet of the exhaust pipe, where all that remains is to take care of the ignition process. The result is a bright and spectacular fire from the exhaust pipe.
