VAZ 21114 engine: characteristics, malfunctions and tuning

The 2111 engine available in the AvtoVAZ manufacturer’s line did not meet the Euro-3 environmental standards existing at that time. In general, the design satisfied the management of the manufacturer’s plant in terms of cost, and the users in terms of technical characteristics. Factory tuning made it possible to obtain a modification of the 21114 engine, different configurations of which comply with Euro-2, Euro-3 and Euro-4 standards.

VAZ-2111 - tuning that you can do yourself

The imperfection of the products of the domestic automobile industry makes every owner of a Russian car an active supporter of all kinds of modifications and alterations of the vehicle. Owners of the affordable VAZ-2111 are no exception. Below we will tell you what owners usually fix when tuning VAZ-2110, 2111, 2112. The listed models are practically the same car, made in different body styles: sedan, station wagon and hatchback.

For lovers of visual effects, the first task will be to refine the appearance of the VAZ-2111 car. No-frills tuning may be limited to replacing the front and rear bumpers, sticking moldings on the sides of the car, and replacing external optical devices. Moreover, there is no need to sculpt something from fiberglass. A striking example is the tuning of the VAZ-2111, a photo of which you can see below. Installing a ready-made bumper with the catchy name “Robot” will completely change the appearance of the car.

The shape of the radiator grille, slanted modern headlights - and before us is a car that looks more like a completely different car, and not a VAZ-2111. We will not consider tuning with deeper modifications to the body in our article. We will study only those variations that are available for self-installation without any problems by the practical majority of owners of a car of this brand.

Those car owners who value personal comfort more are the first to start making changes to the interior. The most extensive work involves installing sound insulation, which entails complete disassembly of the interior.

There is a large selection of materials and means with which you can harmonize the interior appearance of your VAZ-2111 with your preferences. Tuning to change the color of the interior using polyvinyl chloride colored self-adhesive films is quite simple and affordable. You can also install LED lighting in a variety of places - from door handles to the gear shift knob. In addition, you can change the instrument panel or install a more preferable color lighting for the instruments on the dashboard.

For greater comfort, you can change the front seats by taking a replacement from a foreign car. However, this process is more complex, as it involves welding to fit the fastenings of the new seats. In addition, when replacing only the front seats, it is advisable to reupholster the entire interior so that the difference in upholstery does not irritate you and your passengers.

To modify this unit, you must have serious skills and knowledge. Without them, it is not recommended to disassemble the engine to improve it. Therefore, for most VAZ-2111 owners, engine tuning may be limited to installing a turbocharging system and a zero-resistance air filter. This design does not require changing anything in the engine, but it will add power to your engine.

The system can be purchased at car dealerships or automotive markets. Self-installation will not take you much time. The peculiarity of a car with a turbine is that it starts working at high speeds (above 3000). The benefits of a turbocharged engine are obvious - with proper tuning of the engine, the power of the latter will increase significantly.

It should be noted that non-interference with the engine design is only possible when installing a low-pressure turbine not exceeding 0.5 bar. High and ultra-high pressure turbines will require major changes in the design of not only the engine, but also the entire vehicle, from the fuel supply and exhaust gas systems to the braking and clutch systems. But the last option is relevant only for those motorists who decided to create a racing car. Using such a car on everyday trips will be problematic.

Nikolay GANYUSHKIN, head of the engine design bureau

The modernization of the eight-valve engine for front-wheel drive models took two years. The main goals were to reduce fuel consumption and increase dynamic performance by reducing mechanical engine losses, and at the same time reducing harmful vibrations and noise. And of course, increased reliability. Euro 4 standards require that the engine maintain its original emissions parameters twice as long - up to 160 thousand km. And we almost doubled the resource: from 120 thousand to 200 thousand km. The connecting rod and piston group of the VAZ-21116, like the sixteen-valve one, is purchased. In the future, we plan to produce some parts ourselves, and we will continue to purchase some from foreign partners from the Federal Mogul group, who intend to localize the production of components in Russia. We also take into account the interests of the Renault-Nissan alliance. If engine production volumes increase, then it would be reasonable to purchase additional equipment and organize the production of connecting rod and piston group parts in Togliatti.

To disassemble the cylinder head on a VAZ 2190 Lada Granta with VAZ 11183, 21116 and 11186 modification engines, prepare a standard set of tools. Remove the cylinder head from the car. Disassembly is carried out for the purpose of repairing the cylinder head, or replacing attached elements in the event of their failure. Perform the following sequence of actions:

• First of all, it is necessary to remove the intake module along with the throttle assembly. To do this, unscrew the five nuts securing the module to the intake manifold and remove it.
• Next, unscrew the two nuts securing the front thermal insulation shield and the transport eye.

• Remove the insulating shield and eyelet from the studs.
• Next, unscrew the two nuts for the rear fastening of the intake and catalytic manifolds (the same nuts also secure the rear thermal shield).

Remember to be practical

Depending on the nature of the operation, you can install different springs - reinforced or shortened. The latter give the car a more sporty appearance - the car becomes lower, but at the same time the ground clearance decreases. If you load the trunk and there are passengers sitting in the back, it will be difficult for you to move along the road, and getting onto the unpaved surface may be completely impossible due to the colliery of such roads. It is more common to install reinforced springs and install special repair pads under them. When the car is fully loaded, it will not “sit down,” which will make traveling with a full trunk more comfortable.

Maintenance intervals

The 21114 engine is not capricious in operation, but consumables must be replaced according to the schedule presented below, as required by the internal combustion engine design:

If the user has tuned the internal combustion engine, the frequency of replacing some consumables is reduced due to intense wear of friction pairs.

Replacing spark plugs

Tuning VAZ 2111

When doing tuning yourself, it is better to stick to one of the options:

• Design in a classic style, when the car looks more solid
• The exterior style is sporty, when the tuning is more youthful and dynamic.

Thus, for the VAZ 2111 you can use the following installation:

An excellent solution would be to install new shaped headlights, as well as fog lights.

It is also necessary to perform tuning of the VAZ 2111 interior . Especially if its owner is a racer and likes to take part in competitions. To achieve this, the upholstery and seats are completely changed, and the comfort in the cabin increases. The changes also involve the installation of additional instruments and a modernized steering wheel.

Particular attention should be paid to tuning the VAZ 2111 engine. If this car is being transformed into a sports version, then it is best to install stiffer reinforced shock absorbers and springs. At the same time, changes are made to the transmission and braking system.

Exterior tuning

First, we should talk about the bumper. Having decided on a suitable option, you can significantly improve the appearance of the car, especially since today the choice of bumpers is quite extensive. Together with the bumper, you can install a body kit. Each type of bumper implies its own individual style solution. Therefore, it is very important before choosing to decide what kind of exterior styling you want for the VAZ 2111.

You can also install tinted deflectors on your car windows. It's very practical, not to mention fashionable. Anyone who thoroughly and seriously approaches the process of tuning a VAZ 2111 with their own hands will appreciate this solution. These additional elements will increase the level of comfort for passengers while driving with the windows slightly open, and also improve the driver's view of the road in adverse weather.

An excellent solution in favor of functional tuning elements would be to install a rearview camera. This device will be an excellent assistant to the driver during parking, and will also play the role of a reliable eyewitness in case of an accident and in other unpleasant traffic situations.

A modernized air intake will significantly change the appearance and give it some individuality and uniqueness. There are good options for this element for sports cars, which will add even more aggressiveness and dynamism to it. This is an incredible transformation of the VAZ 2111.

In addition to all of the above, you can tune the VAZ 2111 by replacing the wings and hood. These details instantly change the exterior of the car beyond recognition.

Interior tuning

After the appearance has been embellished, it is worth starting tuning the interior of the VAZ 2111. The main “trick” here is to create comfort and convenience for passengers and the driver during the trip. This is the main thing you should strive for during tuning. First, you need to think about what the interior of your favorite car looks like and only then begin to act.

• You can start tuning the interior of the VAZ 2111, starting with the instrument panel and replacing the steering wheel with a more modern one.

In fact, the steering wheel of the VAZ 2111 is not comfortable and simply “screams” for improvement. You can do this yourself.

• You can also think about installing new seats or reupholstering them, but you need to keep in mind that this costs a lot of money.

Here the choice directly depends on the capabilities of the owner. If the owner is able to deal with the upholstery on his own, then he needs to remove the chairs and cover them with the chosen fabric.

The most common problems of internal combustion engines 11186

Malfunctions of the VAZ 11186 begin after 60,000 kilometers, if you do not visit the service center at 40 thousand. Knocks may appear in the VAZ engine. They indicate unadjusted valve clearances

If everything is fine with them, then pay attention to the connecting rod and main bearings of the crankshaft. They may need to be replaced

If the speed in the VAZ engine fluctuates. The problem may lie in a malfunction of the throttle valve. It is necessary to check the functionality of the damper sensors. If they are not working properly, replace them with new ones.

If the thermostat breaks down, the VAZ 11186 engine begins to warm up slowly. When starting, it stalls - problems with the mass air flow sensor. If the mass air flow sensor is not repaired in time, the car may stall while driving somewhere on the highway.

There may be problems with the ignition unit or the standard electronic unit. The latter is unreliable. Therefore, if glitches appear in the control unit, it is better to replace it immediately.

Among the critical breakdowns, experienced mechanics identify problems with the pump and tension roller. If the roller jams, the teeth of the timing belt are cut off. The valve bends in almost every such case. The engine is immediately sent for overhaul. Therefore, it is better to avoid roller wedge and problems with the pump.

Causes of malfunction of injection nozzles

Modern fuel injectors in gasoline engines come in two types: electromagnetic and mechanical. The first is a solenoid valve that is controlled by the vehicle's ECU system. When the appropriate signals are given, the valve opens to a certain angle, regulating the amount of fuel supplied to the cylinder. The second only supplies fuel to the channel. Its design includes a needle with a step. When there is enough pressure, the fuel overcomes the resistance of the spring and the needle rises. Accordingly, the nozzle opens and fuel is supplied to the chamber. Currently, electromagnetic injectors have gained wide popularity as they are more technologically advanced. Therefore, we will further consider checking and cleaning using their example.

There can be only a few malfunctions of the electromagnetic injector:

• lack of signal from the ECU;
• malfunction or complete failure of the winding;
• nozzle outlet is clogged.

As practice shows, it is the latter option that is the most common cause of complete or partial failure of the nozzle.

Your feedback on the modification of the VAZ 21114 engine to 21116

Which cars were included in the package?

Traditionally, for the VAZ company, the 21114 engine was installed on the entire line of cars produced at the time of its inception:

• 21101 – four-door sedan;
• 21112 – five-door station wagon;
• 2113 – three-door hatchback;
• 2114 – five-door hatchback;
• 2115 – four-door sedan;
• Kalina (1st generation) – sedan, station wagon;
• Granta - sedan, liftback.

Improved engine characteristics significantly increased the service life of the “ten” and the Lada Samara-2 series.

We increase the power of the 8 valve VAZ-2114 engine with our own hands - myths and reality

It's no secret that in its standard, that is, in serial form, the engine does not develop all the power it is capable of. You can configure the firmware in a new way, but you won’t be able to significantly change the load curve without reducing the environmental class. You can buy a "racing camshaft" to install in place of the stock one. But then the firmware will have to be changed to accommodate the new phases... Let's consider what happens if we use only accessible tuning methods. Let's say right away that on the VAZ-2114 hatchback the increase in power can be 20% or even 25%, and we are talking about only 8 valves. There is no need to bore the valve channels.

Repair of power unit components

As practice shows, nothing lasts forever, and neither do the components of VAZ power units. In this part of the article, we will consider the main malfunctions, as well as methods of elimination and repair.

Timing belt or how not to bend valves

Probably the most interesting question for most motorists is whether the valves on VAZ engines bend? As for the VAZ 11189 engine, we can say with confidence that the valves bend when the timing belt breaks. Of course, valves can bend for other reasons, but the most common is considered to be a broken timing belt.

Another question that car enthusiasts ask in car repair shops and on forums regarding the timing belt is how to prevent valve bending? Everything is very simple - change the timing belt and rollers according to the technical recommendations of the manufacturer. Thus, in the maintenance manuals for engine 11189, the recommended belt replacement period is 45-50 thousand kilometers.

What happens if the valve bends? Everything is very simple - after the valve mechanism is bent, such important elements as the valve guide, valve seat, and oil seals fail. Subsequently, it may happen that this problem affects the piston mechanism. In a word, if the valve bends, then you should hope for the best and expect the worst - that is, a major repair.

How to replace the timing belt and rollers:

The procedure for changing the timing belt, at first glance, seems to be quite simple, but not everything is so simple, and not every car enthusiast will be able to carry it out. Therefore, in order not to subsequently bend the valves, it is recommended to contact specialists at a car service center to carry out the procedure.

Water pump malfunction

The water pump circulates coolant through the engine system. This is done for cooling and to prevent the motor from burning out. The failure of such a unit means that further operation of the power unit is impossible, since overheating will occur and the first thing that will be affected is the cylinder head. To avoid this, you should regularly diagnose the part and replace it on time.

There is nothing difficult about replacing the pump. The procedure is similar to changing the timing belt. After removing the belt, unscrew the bolts securing the water pump and replace it. It should be noted that the coolant must be drained from the system and, after replacement, topped up to the required level.

An example of increasing the power of a VAZ-2114 engine

During the tuning, the 2111 (1.5 l) engine was modified.

Boring of seats along the internal diameter, which is equivalent to enlarging the valve;

Valve seats, VAZ 2111 engine

Our new engine remains “not plug-in” - the valves do not reach the pistons. When tested on a bench (the sensors were turned off), the result was not impressive.

Checking without adjusting the ECU

If you install the engineering firmware, you can select the parameters “from start to finish.” And then the picture looks better...

Torque graph after tuning is completed

All sensors, including the lambda probe, were connected in the latter case. We managed to get 96 “forces” at 5300 rpm!

How not to increase power!

• Do not attempt to bore channels. This operation can be performed in the absence of ball cutters, but in garage conditions nothing will work even with cutters. The bottom line is that the accuracy of the cutter installation is important - the error should not exceed 1-2 microns.
• As you can see, on the stock VAZ-2114 hatchback the increase in power was 24%, and this is without installing a “chandelier”, “improved exhaust” and other expensive elements.
• There is no point in buying a “racing camshaft” without having the appropriate tuning firmware.

Characteristics of engine 21128

Toyota 1nz fe engine: characteristics, faults and tuning

The priority task of the Super-Auto manufacturer was to increase the power of the 21124 internal combustion engine, which does not bend valves, which was taken as a basis, so changes took place in the engine:

• the engine diagram remains the same - DONS timing diagram with 2 overhead camshafts;
• a volume of up to 1.8 liters was added - the combustion chambers were enlarged, the cylinders had a size of 82.5 mm, the piston stroke was added to 84 mm;
• the safety of the valves is ensured - deep holes protect them from bending when they meet the pistons at the moment the timing belt drive breaks;
• compression ratio 10.5 units;
• Controller firmware January 5.1, throttle pipe cross-section 51 mm.

Forced motor 21128

As a result, the manual contained a description of the engine parameters - power in the region of 95 - 105 hp. With. and torque at 3200 rpm is about 160 - 162 Nm. The pistons were designed jointly by engineers from AVITI and Super-Auto, since a similar size did not exist in the AvtoVAZ line in principle. The connecting rods are also created for this internal combustion engine, length 129 mm, fastening with a 19 mm pin, fit on a non-standard crankpin 41.5 mm.

With a declared service life of 150,000 km, the manufacturer’s engine could not withstand 100,000 km and consumed a lot of oil - up to 1 liter per 1000 km. The environmental standard has dropped to Euro 2. A “long” piston stroke leads to increased loads on the side surfaces of the cylinders and intense wear of the rings/pistons. This results in high engine oil consumption and the system overheats.

https://youtube.com/watch?v=MkhhtUVGEBQ

A year later, Super-Auto management removed the ICE marking 21128-26 from production, replacing it with the following version designated 21128-27:

• the engine does not bend the valve, so a conventional timing belt with a service life of 50 - 90 thousand km is installed;
• cylinders returned to 82 mm size, lightweight pistons from Federal Mogul;
• Mecaprom connecting rods were used;
• a new version of controller firmware has been created;
• valve lift increased to 8.3 mm (0.7 mm more than the original);
• The eco standard has increased to Euro-4.

Modified version of the motor

Since two versions of the 21128 motor were developed, the technical characteristics have changed over time:

Even after modification of the power drive, major repairs are possible after 150,000 km. This is due to the remaining “long” piston stroke, increased loads on the cylinder walls, and intensive production of ShPG parts.

What to do with engine 11183?

It is clear that a mandatory step in tuning the 11183 engine will be replacing the ECU. It’s simple: the standard M74 block cannot be flashed, but “January 7.2” is a good and time-tested solution. You will also have to abandon the “E-Gas” option, which means replacing the throttle assembly and receiver.

Everything I had to throw away

The intake tract parts were borrowed from the 2111 engine. A cable pedal was installed, and the engine began to look human.

Everything works well with the “January” controller, but standard firmware is not an option if the camshaft has been replaced. And it, in turn, has the following parameters:

After installing the new shaft, the motor became plug-in. However, on the 2114 hatchback, increasing power almost always comes with a compromise. In this case, we had to sacrifice reliability. What's improved:

• Maximum torque increased by 14 N*m ;
• The power also increased – the limit of “90 horsepower” was passed.

By the way, any tuning leads to a decrease in durability. Make a choice.

Model features

The developers have built into the 21114 engine a potential of within 120 hp. With. without reducing service life. For sports cars, boosting up to 180 hp is possible. pp., but the production of piston and CV gears will increase sharply, and major overhauls will be required more often. To improve engine parameters, the timing structure has been modified:

• camshaft drive by toothed belt;
• pin at the end of the camshaft for reading by the timing sensor.

All available attachments are driven by one belt. Another feature is the partial integration of the exhaust manifold with the exhaust system. The resulting catalytic collector includes a catalytic converter and a muffler exhaust pipe.

Catcollector

The polymer receiver has a configuration that differs from the shape on the basic version 2111. In the fuel system, the return line is replaced by an injector ramp, which by default is equipped with either Boshevsky 0280-158-022, or yellow VAZ 20734, Siemens injectors. Instead of the ignition module there is a coil with 4 pins; the ECU uses an M7.9.7 or January version 7.2 controller.

Four-terminal ignition coil

The cooling system is equipped with a new thermostat, and the internal combustion engine includes an 80-amp generator. The repair manual contains a step-by-step description of all operations, for example the procedure for changing the oil. The manufacturer recommends not using turbines when upgrading engines with your own hands.

Method for increasing the power of an 8 valve engine with a split gear

The split, that is, adjustable gear was not used in the last project. It is better to install it on “non-plug-in motors”. Setting method:

1. The moving and fixed parts are marked with a mark, the same as on a standard pulley;
2. Installation is carried out in the usual manner, aligning the crankshaft and timing mechanism according to the marks (as when replacing a belt), you should also remember about the correct tightening torque of the belt;
3. If in the 4th cylinder the intake and exhaust valves are not open “to the maximum”, we carry out an adjustment: loosen the outer screws, and, holding the outer part of the gear, set the camshaft correctly. Tighten the fixing screws.

Split gear with retaining screws removed

Reliability, weaknesses, maintainability

These three main indicators complement the technical characteristics of the engine in sufficient detail and give a more complete picture of the power unit.

Reliability

VAZ-21114 is one of the few engines with high reliability. Car owners have repeatedly spoken about this on forums. Car service technicians share the same opinion.

For example, the engine of a Lada Kalina 1117 with a mileage of 130 thousand km was inspected. The result was amazing. The pistons are clean, the hone on the cylinder walls is preserved, and there is no carbon deposits on the valves.

The car owner draws attention to the fact that the oil was changed after 7-8 thousand km, and the gasoline for the first 90 thousand km was exclusively AI-95, then it was replaced with AI-92.

Reliability is clearly evidenced by the fact that with a lifespan of 150 thousand km declared by the manufacturer, the engine lasts for more than 300 thousand without repair. And this is not the limit.

The engine has a large margin of safety. With proper tuning, its power can be increased to 180 hp. With. It should be taken into account that such modification of the motor is very complex, expensive and significantly reduces the declared service life.

The reliability of the motor is significantly increased by reducing the maintenance time, using high-quality technical fluids and its reasonable operation.

Tuning parts, popular and not so popular

We have arranged all the elements in order of increasing uselessness:

Receiver with increased volume. After replacing the standard unit, there is an increase in output at medium and high speeds. But for the region of 1000-2500 rpm, it would be preferable to have a standard receiver.

Receiver with increased volume (shorter path)

Tuning throttle assembly

As for the exhaust tract, you can install a “4-2-1 spider” - it creates a vacuum in front of the valve that is not yet open... Torque and power are improved from this, the question is by how much.

Any “tuning” begins not with the engine, but with the selection of “gear ratios”... This advice is common, and it also applies to the VAZ-2108 and 2114 families.

Vehicle specifications

Motor 21124

This is the most favorite type of power unit of many VAZ 2110-2112 owners, as it has a number of advantages over others, such as:

• increased power up to 92 hp;
• low fuel consumption;
• no problems with “bent valves”, since from the factory the pistons are equipped with recesses that prevent the “ill-fated” meeting of pistons and valves.

It is because of all these advantages that many people prefer to buy cars with such engines. But if you look at the complexity of maintenance, then naturally the 8-valve will be simpler in this regard.

If you want a simpler and more reliable design, then these are 8-valve machines. If power and dynamics are important to you, choose the 16-valve option. But again, keep in mind the modification so that there are no problems if the belt breaks.

Description

Like all previous models, the VAZ 11183 engine is a classic four-stroke, in-line, 4-cylinder power unit with an overhead camshaft.
The increase in cylinder volume was achieved through the use of a higher cylinder block than that of the prototype. Its height is 2.3 mm higher than the height of the 2111 engine block and is 197.1 mm (from the crankshaft axis to the top surface). The diameter of the cylinders did not change, but the dimensions and shape of the combustion chamber had to be changed.

The cylinder head is made of aluminum alloy. A camshaft is installed in its upper part, and special ducts are cast in the lower part, designed to supply coolant to the combustion chambers. The same channels are also available in the cylinder block housing.

The crankshaft and camshaft of the engine are cast from cast iron, the pistons are made from aluminum alloy. Forged connecting rods (steel).
