How to increase engine power VAZ 2109 injector 8 valves

Engine tuning VAZ 2109

As a rule, engine tuning on the VAZ 2109 is carried out by car owners interested in enhancing the power and dynamics of their vehicle. VAZ 2109 engine tuning is a unique opportunity to improve the technical characteristics of your car.

Note. Checking and upgrading the brakes and gearbox is a classic start to tuning. After these components are finalized, the actual process of tuning the engine begins.

Modification Basics

The goal of any changes is to increase power and improve dynamic performance. The tuning unit becomes more durable. The concept of high-quality modernization includes the installation of updated elements:

• cylinder head;
• sports receiver;
• intercooler or turbine;
• camshaft;
• piston group.

In the process of working on the cylinder head, the shape and diameter of the intake valves and combustion chamber change.
Often, the VAZ-2109 is equipped with spare parts from other cars, for example, an additional carburetor and manifold, which are taken from the Oka. Such a modification is not possible if your VAZ-2109 has an injection model of the power plant. The carburetor VAZ-2109 models have only one advantage - the power unit is capable of running on low-octane gasoline. It is a little easier to repair than the injector. You should not radically change the power unit if you have a carburetor type - modify it rather than install a new injector. Such a change is very costly in terms of finances and does not justify itself. It is better to use other methods of modernization.

Where to start?

Let's look under the hood of the car and, through easy inferences, figure out the involvement of the motor in this story. The engine is the “heart” of any car, and the investigation should begin with it. The plant for the production of serial models equips a typical VAZ 2109 with a carburetor with a capacity of 1.5 liters, which gives the chance to extract approximately 70 horsepower from the engine shaft.

Not much, not little, but quite enough for an ordinary trip around the city. But if you are not satisfied with the usual driving with the breeze, and your heart, as in the song of the same name, requires “change” and you want something tougher, you will have to think about tuning and improving this part. There are options for buying another car, changing the engine, but who needs this extra hassle, not to mention the financial component of this issue. If we had millions, would such topics about car tuning and engine changes even begin to open? Everyone would have been driving around the city in brand new Audis long ago, and the problem of changing equipment would have disappeared by itself.

Let's get back to the heart of the matter. As you may have already guessed, one of the best options to increase acceleration is to change the carburetor, or, well, modernize it, whichever is more convenient for you

It is also worth paying attention to changing the cam shaft in order to increase the intake-exhaust time of the air-fuel mixture, which is achieved by a different form of cams on this same shaft

Everyone knows that factory production “saves” on car parameters because of the damned GOST standards that are imposed on them. But we are not a factory and we are not aware of all these artificially created restrictions, and therefore we have every right to dispose of our car the way we want. For this reason, we are unlikely to harm anyone by installing a new high-quality filter

There are, however, a number of disadvantages, for example, the abandonment of a standard filter, the future fate of which remains a mystery to everyone, or an increase in noise level, but we do not think that this will have a significant effect, so we will not focus much attention on this

There is also an alternative option for installing an additional injection system, but in this case it is necessary to abandon the car body, and there is not much space left for the filter, which is also a significant disadvantage. We have to pay for everything in our lives, and while improving one parameter, we must be prepared for the deterioration of another. The average cost of this “homemade product” will cost the buyer about 100-150 dollars, but the engine power will pleasantly please thanks to an increase of 5% from its previous performance.

Methods for tuning the power unit

There are many ways to improve engine performance. Before work, keep in mind that in case of an error you will have to completely change the unit. Each method of changing motor characteristics has its own advantages and disadvantages. Here are a few relatively safe tuning methods:

1. Installing a zero resistance filter. Craftsmen often call this component “zero”. If you choose the right filter, the dynamic performance and motor power will increase by 5%. If you equip your car with a zero drive, then you will have to carefully monitor it and clean it in a timely manner. Otherwise, installing the element will be pointless and dangerous. A dirty filter poses a risk of engine damage. Focus on a price of 5 to 6 thousand rubles per filter. Instances that cost less will not work normally.
2. Together with injection power units, it is often recommended to use direct-flow mufflers. This part should only be used in the gas exhaust system if you have carried out a thorough modernization of the engine. Another option when such a muffler would be appropriate: if the car has a turbo air injection system (additional compressor). The straight-through muffler will only affect power in conjunction with other upgrades. In other cases, installing it is a pointless waste of money. It will make the car noisier and a roar will be heard when driving.
3. Another effective way to increase engine power is to install a sports range on the gearbox. At the same time, a 6th gear will be added, and the car will accelerate more dynamically due to a change in a number of gear ratios. The overall engine power will not change, but the dynamic characteristics will become noticeably better. At the same time, replace the piston group and install a more powerful engine. Deep reworking of the engine and gearbox will allow for a qualitative change in the power plant. You will feel the dynamics already when you first start the engine and accelerate. Such tuning will be expensive, but it will be worth it.
4. Chip tuning is most often recommended for injectors. Using a simple laptop, a small amount of equipment and application programs, the ECU is configured. The advantage of this method is its low cost - you do not have to carry out mechanical work or interfere with the elements of the unit. If you make a mistake, it will be enough to replace the on-board computer. It will cost less than replacing an engine if another type of tuning fails. After flashing the ECU, you will immediately notice a change in engine performance.

There are many techniques with which you can change the characteristics of a carburetor and injection model. Most work is carried out mechanically. If you have never encountered routine engine repairs until now, and you have little understanding of the principle of its structure, then entrust the modernization to professionals. They will offer you a change program and do the job efficiently.

Timing device VAZ 2110 injector 8 valves

Many people are concerned about the question: Do the valves on the VAZ 2110 injection engine bend? No, it doesn’t bend, the 8-valve injector does not suffer from this defect. But this does not mean that you should not monitor the timing belt. Since loosening and subsequent jumping of the belt by a certain number of teeth will lead to inevitable problems

It is worth paying special attention if engine oil gets on the belt; an oiled belt will not last long. Below is a detailed image of the timing diagram of the 8-valve injection engine "tens"

See the photo below.

When replacing the timing belt on a VAZ-2110, it is necessary to clearly align the marks on the camshaft and crankshaft pulleys; without this, the engine will not operate normally. Another important point is that when the tension roller moves to its original state, the marks shift as the belt tension changes. Therefore, carefully check whether the timing marks are clearly aligned before putting on the cover covering the timing belt.

Note. Checking and upgrading the brakes and gearbox is a classic start to tuning. After these components are finalized, the actual process of tuning the engine begins.

Characteristics of the motor 2111

Since 1993, the manufacturer AvtoVAZ opened the VAZ-2110 project. A front-wheel drive luxury sedan was being developed, so carburetor modifications of engines 2108, 2110 and their variants did not meet the conditions.

Already at the initial stage, the project was divided into two independent works. A simple conversion of the G8 hatchback into a sedan was called VAZ-21099. The name of the second project remained the same, but work on it was considerably delayed for a number of reasons:

• in 1985, a test sample appeared; the car with the new engine was planned to be launched into series in 1992;
• the crisis confused plans, the management of the manufacturer's plant put the VAZ-2110 on the assembly line only in 1996;
• The first cars had a carburetor internal combustion engine, then a modified 2111 injection type.

Motor diagram

The designers managed to make maximum use of existing engine elements so that the user of previous generations of VAZ would not be confused about which oil and coolant to use. By default, the technical characteristics of the ICE 2111 are as follows:

Increasing the power of a carburetor engine

What is engine tuning? Typically, this is an increase in engine dynamics and power. Various components are modified and subjected to grinding, polishing and boring. Tuning the VAZ 2109 engine can be easily done independently. To do this, various methods are used, depending on the amount of money the owner of the vehicle has. The most expensive tuning option is replacing the standard engine with a more powerful power unit.

Crankshaft replacement

If you install a different crankshaft on the “nine” (with a larger crank radius), you can achieve a high piston stroke. Accordingly, the cylinder volume will be larger (that is, the engine will become more powerful). In this case, the VAZ-2109 will not “eat” more fuel, and its dynamics will increase significantly.

True, this is a more expensive method than boring a cylinder block. Among the new parts that need to be purchased for this work, the following should be highlighted:

New crankshaft. The diameter of its crank must be from 75 to 80 millimeters.

Set of new pistons. You should choose those that will best fit the purchased crankshaft

It is important to consider that the cylinder block has its own maximum height and a very large piston will not work in it.

Piston rings (compression and oil scraper set).

In addition, you need to find a master who will carry out the work of boring the block for a given set of pistons. In terms of time, the entire engine tuning (VAZ-2109-21099) can take from 1 to 3-4 weeks.

Engine tuning options

VAZ 21093 engine tuning

As mentioned above, engine tuning involves several methods. They all have both their advantages and disadvantages.

Engine modernization in the first way

This option involves installing and replacing the following components:

• Lightweight connecting rods, which fit the size 121 mm.
• A lightweight crankshaft, the piston stroke of which should be 78 mm.
• Lightweight piston rings.
• Cylinder head borrowed from Lada Kalina.
• Forged pistons having a diameter of 82.5 mm.
• Camshaft size 11.3 mm.

Note. This modification of the engine gives considerable power, which in l/s is equal to 98. This also makes it possible to reach a maximum speed of 183 km/h.

Method two

This method involves upgrading the engine by interfering with the operation of the transmission and carburetor. In this case, such modernization will not require too high financial costs, unless, of course, the work is carried out on its own. So:

• The first step is to install a new filter, which should have a diameter of 70 mm. This filter must have a direct-flow outlet device. This will make it possible to increase engine power by 10 l/s.
• We install a 5-speed transmission.
• We install a new oil cooler.

Option three

This method of engine modernization involves the installation of the following parts:

• New oil nozzles.
• Lightweight pistons.
• Lightweight crankshaft.
• New gearbox.
• Lightweight flywheel.
• Improved grip.

In addition to the above, a lot of new components are installed on the car, including a non-contact ignition system, a sports muffler (see: We do high-quality replacement of the muffler on a VAZ), a copper radiator, and so on.

Carrying out mechanical processing to change the design of the cylinder block

The performance characteristics of the engine can be significantly changed by machining the internal surfaces of the internal combustion engine cylinder head. Certain changes can significantly change the characteristics of the engine. The main goal that many people want to achieve is to significantly increase the degree of filling of the cylinder. The greater the fuel-air mixture, the more power the installed unit has.

The engine that is installed on a car at the factory does not have a perfect design. Almost all structural elements are far from ideal shape

In mass production, attention is often not paid to the quality of the channels. Based on the peculiarities of the law of flow of liquid and gases through channels, it can be said that the tube must have an absolutely flat and straight surface

When the valve is open, the mixture enters the combustion chamber, which determines the swirl of the flow. After this, the flow breaks down and enters an area with a large volume; the valve resists the movement of the air-gas mixture. Tuning the VAZ 2108 engine allows you to significantly reduce resistance, which means efficiency increases significantly and engine power increases.

Insert: Important: When producing a cylinder block, it is taken into account that the internal surface must be without various differences. The valve should have a flat shape with rounded edges, like a seat

The treatment is also carried out so that the mixture returning to the cylinder does not stop abruptly, that is, the power does not drop; the shape at the point where the mixture exits the channel is processed. Such a change allows not only to significantly increase the volume of each cylinder, but also to increase the maximum time during which the valve remains open. Increasing the start phase allows you to increase the power of the installed motor by 30, 50 or even 100%. However, it is worth remembering that the design of the original motor is not designed for such high power, which means the service life is significantly reduced.

Some features of engine tuning

In the process of improving the performance of the VAZ 2109 engine, the following actions can help:

• Weakening the friction force in a chain consisting of a ring, piston and cylinder.
• Reducing the weight of some parts, such as connecting rods, pistons, and so on.
• Reducing the thickness of the piston rings, as well as reducing their number.

Injection engine tuning

If everything is more or less clear with the modernization of a carburetor engine, then an injection engine will require several different tuning methods. In this case, no mechanical intervention is needed, because in order to change the technical characteristics, it is enough to adjust the ECU settings.

Chip tuning

Engine tuning for VAZ 2109

Modernization of an injection engine is also called chip tuning. Here are the main advantages of the so-called chip engine:

• The manufacturer sets average values ​​for the engine and other important vehicle parameters. This is done in order to comply with the general rules and requirements of car markets around the world. Cars have a certain hidden reserve that can be revealed thanks to chip tuning.
• Engine power can be increased without using any mechanical operations. At the same time, such parameters as the maximum speed of the car, its dynamic characteristics, and so on change.
• Chip tuning allows you to change fuel consumption, increase engine speed, and adjust the ignition just by changing the settings.

How is chip tuning carried out?

• The ECU is removed from the car.
• From there, the memory chip is removed, which has saved all the set parameters.
• Information is read from the chip using a programmer.
• Next, the necessary changes are made to the chip and new values ​​are recorded.

Note. Often you can change the values ​​in the chip without removing it by connecting the ECU to a special plug.

Some argue that after increasing the power of an injection engine, fuel consumption increases sharply, but this is an erroneous opinion, because this is observed for a short period of time, and then everything returns to normal. The service life of the engine does not decrease after chip tuning. Above, general instructions were given regarding tuning the VAZ 2109 engine. This information concerns modifying the engine settings with your own hands, without the participation of specialists, which makes it possible to save a lot of money. The fact is that the price for any professional modification of the technical parameters of a car at service centers is very high. Why pay that kind of money if, together with photos and videos, you can do everything yourself.

We resort to serious processing - boring the cylinder block

You can also increase the engine power by boring the cylinder block. Due to this, the volume of the combustion chamber increases, which means that a larger amount of the fuel mixture is placed in it. When choosing this method of modifying an installed motor, the following points should be taken into account:

Increasing the volume of cylinder blocks does not lead to a significant increase in fuel consumption. This work can only be carried out if you have certain experience and equipment. When changing the design, one should take into account the fact that the walls of the cylinder block become thinner. At the same time, the design has channels for the cooling system

Therefore, attention should be paid to the calculations carried out

Boring a cylinder block yourself is possible only if you have the required equipment and certain skills. The surface must be strictly cylindrical and free from significant defects. Otherwise, the engine will begin to wear out quickly.

What will happen to us for this?

Sports cars are famous for their noise effects, and driving down your street sometimes leaves the impression of the start of a nuclear war. It’s quite simple to explain - the exhaust system is just configured a little differently than other cars in this series, which leads to noise that is unpleasant for city residents and pleasant for the driver. Feel the power hidden under the hood of your almost-Mustang. Having lost in noise, you will get another more pleasant nuance - an increase in engine power within 3-5 horses, which will make any car enthusiast rejoice with joy.

Here you need to give a clear example with the installation of any product, the cost of these parts is relatively inexpensive ($250-300), but the result will not take long to arrive. After installing such a thing, your previously choking old VAZ 2109 will get a second wind and start thundering in a completely different way.

If you follow strictly the instructions given above, pay attention to the jets and understand a little about ignition issues, you can increase the engine power from 5 to 10 horsepower, without any damage to engine life.

First aid for a car

The first step in such cases is to check the battery terminals; perhaps they are not making good contact. If there is poor contact at the battery terminals while driving , it will not be charged sufficiently, which may cause problems during further operation of the car. To fix this problem, you need to lubricate the terminals and tighten them.

If your car's alternator fails, you need to have it repaired immediately. the voltage regulator fails . The failure of this generator element has rather unpredictable consequences. While driving, the regulator controls the required amount of current for the car; if it fails, the voltage in the network changes and can be either more or less. Very often, fuses blow at high voltages.

2109 voltage regulator is located directly in the car’s generator itself. When it fails, most often the generator relay breaks. It consists of several elements such as an electromagnet, an armature and a switch. These elements interact with each other when electric current is applied to them.

How to properly adjust the quality of the mixture?

In order to change the driving characteristics of the car, you can fine-tune the quality of the mixture. Considering this question, we note:

1. We completely line up the carburetor.

2. Install the necessary jets.

3. If the spark plugs flicker or are white due to a slight enrichment of the mixture, this is a sign of a problem with the quality of the mixture.

4. Adjustment should be made using a special screw.

5. Adjustment using a screw is only possible when the EAC system is turned off, since fuel is added from the idle system, and this has a strong influence on the behavior of the engine.

6. If the screw is tightened tightly, then the mixture is lean.

7. To obtain the required quality, a small unscrewing is carried out when the ratio becomes 14.7 air to one part gasoline.

If you need to save money, you can tighten it a little; if you need a fast car, you can unscrew it slightly. Note that you also cannot overdo it with unscrewing.

A few important points

I would like to note that any modifications to the VAZ-2110 car must be carried out in a place prepared for this. If you are going to upgrade the carburetor, it is advisable that the room is well ventilated, because you will be dealing with gasoline vapors. It is also better not to smoke while performing work; sometimes you even need to wear special glasses. It is also worth paying attention to the fact that it is advisable to have clean water and dry rags with you. All of this will help you in one way or another. When it comes to working with the engine, remember that if you are not sure about something, it is better to read about it again or find out from a mechanic you know, because you can only make things worse, and engine repair is not cheap. It is worth noting once again that if you are modifying the stove, then it is best to buy corrugations at a car dealership, as they will be more suitable for your purposes.

Also, many car owners want to make the car a little quieter, so they install their own sound insulation for this. Here, too, it is advisable to go to a specialized store and not save money, then the result will please you. Remember that the VAZ-2110 car, which you will modify with your own hands, although it is the brainchild of AvtoVAZ, it is a pretty good and demanding car. Therefore, before adjusting the steering rack, add oil, perhaps the situation will improve. Before sinning on a faulty carburetor, change the fuel and air filters.

Specifications

Before we begin to describe the process of refining and increasing the power of the VAZ 2109 carburetor engine, it is worth understanding what power units were installed on the vehicle, and also consider the main technical characteristics.

During the production process, the “nine” was equipped with three options for carburetor engines:

21081 (1.1 8V)

2108 (1.3 8V)

21083 (1.5 8V)

Refinement of the cylinder head

Oddly enough, increasing the displacement is not always a profitable method of boosting the engine. Sometimes motorists resort to modifying the cylinder head and replacing the camshaft with a tuning one (that is, non-standard). In fact, this method is truly impressive in its effectiveness. However, this requires a lot of time and effort, since the modification will concern not only the block head. This may include pressing in other seats or installing new valves with a larger diameter. If you make such an engine repair, the VAZ-2109 will be 5-15 percent more powerful, depending on the amount of work done.
