Specifications. Adjusting and checking the carburetor All about the car VAZ 21093 carburetor

VAZ 2109 carburetor tuning is a popular and very popular topic lately. From the article we will learn how to do this.
On the VAZ 2109, tuning a Solex carburetor or a carburetor of another production is carried out for only one main reason - to increase the power and dynamic characteristics of the car.
To increase power, experts disagree, it is necessary first of all to refine the power unit itself. Yes, this is true, but if there is not enough budget, you have to take risks.
Modifying the carburetor, without improving the other important elements, is, of course, a risk, but in some cases it is justified.

Device

Before tuning, you need to know how the Solex carburetor works. It was produced in several modifications and either DAAZ-2108 or DAAZ-2183 was installed on the VAZ 2109.
The first of the carburetor modifications was installed on a 1.3 liter engine, the second - on a 1.5 liter one. These carburettors are devices that are designed to accurately meter fuel into the air stream.
The Solex carburetor also differs in the following features:

• It is in the carburetor that the process of formation of a combustible mixture from fuel and air takes place, with its subsequent supply to the engine cylinders (see);
• Note that the Solex carburetor has two vertical channels called chambers.

Note. A throttle valve is provided for the passage of air at the bottom of each chamber.

• Due to the fact that there are two chambers, and the damper drive is designed in such a way that as the gas pedal is pulled, one and then the other channel opens, such a carburetor is called two-chamber.

Note. The chamber that opens earlier is called primary, and the one that opens later is called secondary.

• Among the main features of the carburetor, we note also the tapered constrictions, called diffusers. They are needed in order to create a vacuum required to suck fuel from the float chamber (a special container in the carburetor body).

Note. The fuel level in the float chamber is kept constant to ensure normal carburetor operation.

• Solex carburetor consists of two main parts: upper and lower. The flanged body, air filter retaining studs and fuel fittings are what the upper part consists of.
  The lower part consists of a body, diffusers, a float chamber, etc.

Technical parameters of DAAZ-2108/2183 carburetors

Classic tuning

To carry out tuning of the Solex carburetor, the following operations must be carried out:

• Dismantle it yourself;
• It is good to clean it from dirt;
• Remove the jets and throttle valves (carried out for boring diffusers);
• Both chambers must be enlarged on a special machine;
• Grind the carburetor to reduce the resistance of the incoming air;
• We select the right ones for the now modernized carburetor.

Selection of jets

The selection of jets is the most difficult process. They should be selected taking into account not only coincidence, but also high accuracy.
Thus, the high-pressure liquid must be selected so as to allow a certain amount of air to pass through, which would be equal to the amount of fuel passed through the fuel liquid. Otherwise, the fuel mixture will not be properly balanced, which will inevitably lead to poor acceleration and other problems.
In addition, the jets must be properly balanced. It is necessary to approach this issue with all responsibility, realizing that the instability of the fuel level will lead to a depletion of the mixture.

Note. As you know, the ideal level is 1 mm. The rest of the levels lead to malfunctions and loss of power.

In the process of tuning the carburetor, it is also recommended by specialists to install a locking needle made of rubber, which provides a more reliable level during heavy loads. In addition, such a needle is durable and able to get rid of hang-ups when the accelerator pedal is pressed sharply.

Two carburettors instead of one

This approach is also seen as effective tuning. This idea has quite sound reasons. It would seem why the engineers themselves did not think of this at the design stage of the VAZ 2109 car, but this is a different story.

Note. Experts and tuners see one of the main reasons for installing two carburetors instead of one in the fact that due to the oddities of the design on the power unit "nine" different lengths of the manifold pipes. Because of this, not entirely clear situation, more fuel gets into the chambers of the 1st and 4th cylinders of the engine, and less into the rest.

This error can, of course, be corrected by polishing the collectors and both chambers from the inside. Such a procedure will allow more mixture to enter the chambers, as a result of which the flow resistance will drop, the quality will improve and everything will become much more efficient.
But, nevertheless, this is not ideal - installing two carburetors instead of one looks much more attractive.

Important points

Here are the important points to consider when installing:

• Both carburetors must be of the same model (in this case Solex);
• It is also necessary to install two filters and prepare the appropriate number of fasteners, tees, hoses, and so on;
• After installation, which is not that difficult in itself, it is necessary to tune both carburetors, which is considered a more difficult operation.

Note. The carburetors can be adjusted using a vacuum gauge bar or an IKS-1 mixture quality sensor screwed into the place of the candle. So, in order for the adjustment to be correct, it is necessary to observe the color of the mixture at idle and ensure that it becomes light blue.

Algorithm for carrying out the installation on their own

Here's what to do:

• Take two Solex carburetors;
• Bring them into proper form and equip them with a repair kit;
• Purchase two collectors from the Oka car, which will serve as the basis for the intake tract (you must also make your own transition manifold).

Note. On the "nine" you can install two carburetors without mounting an adapter, but then you will have to cut a lot, connect, etc.

• Next, you need to synchronize the work of the carburetors by opening the dampers on both of them.

Advice. As a drive for the dampers, it is advisable to use traction from Ozone, but not cables from Tavria, which stretch.

• After installing the carburetors, we connect the fuel hoses and two return lines through the tees;
• It is imperative to plug the fitting on one of the collectors;
• We start the car (with half a turn) and check everything.

Pros and cons of a double carburetor on the "nine"

Tuning is a responsible but entertaining process. Before conducting it, it is recommended to study useful photos - materials, diagrams and drawings, watch a video review, scroll through the instructions.
As a result, we carry out modernization with our own hands, which will certainly come in handy.

Adjusting the carburetor of a VAZ 2109 is the most common car maintenance procedure. Due to the complexity of the knot, it is considered the finest and most sensitive tuning in a car. It's time to find out how the VAZ 2109 carburetor is adjusted and repaired.

Before cleaning and adjusting the carb, it is necessary to study the data of the carburetor. This is a table that has content in the form of technical characteristics.

Before adjusting the carburetor on a VAZ 2109 car, you need to familiarize yourself with the associated malfunctions so as not to repair the unit just like that.

So, the reason after which the VAZ 2109 carburetor is tuned is considered:

• Fuel mixture too rich... Experienced auto mechanics know that an ideal ratio of fuel to air requires a value of 1 to 15. This means that for the combustion of 1 kg of fuel, 15 kg of air is needed. If the mixture is called rich, it means that the fuel level is higher than the nominal one.
  

  Symptoms: the engine does not start well, black smoke from the exhaust pipe, candles with black carbon deposits and holes in the exhaust system. The fuel supply system quickly clogs up.

• Too lean air-fuel mixture... Lean mixture - means that too little fuel is supplied. Because of this, the car loses in dynamics and increases the amount of fuel supplied. In some cases, gasoline savings are observed, but spark plugs fail faster. Depletion of the mixture is accompanied by an increase in engine idle speed.

The following signs can be called a consequence of the previous ones, and this:

• Unstable idle speed;
• Increased fuel consumption;
• Deterioration of starting properties;
• Decreased engine throttle response.

The principle of operation of the carburetor and the fuel supply system forces car owners to perform a procedure such as adjusting the VAZ 2109 carburetor at least once every six months. The mechanism on a car with carbide needs to be lubricated once a month, in contrast to a car with injection, where there are nozzles. Everything is regulated very simply.

Reasons for the failure of the carburetor VAZ 2109

The Solex carburetor is a very sensitive device with a large number of small channels. When a huge amount of low-quality fuel passes through them, you may be faced with the fact that they become clogged with impurities and stop functioning.

The first thing that can immediately become noticeable is a decrease in idle speed. In the future, the car does not start well and needs carburetor adjustment.

This procedure is divided into several stages:

1. Removing the unit
2. Disassembly and cleaning
3. Assembly and installation
4. Carba idle speed setting

Removing, disassembling and cleaning the carburetor VAZ 2109

If all of the above symptoms are found, you can start removing and disassembling the carburetor. On the VAZ 2109, the repair of the Solex carburetor is possible with use. It is recommended to purchase in advance in order to immediately change all gaskets, jets and valves. The table contains the data of the nozzles and all the required valves. The machine must be stationary. When analyzing the details, the most important thing is not to lose anything.

To remove and adjust the device, you must open the hood and disconnect all hoses from it. They are attached with clamps, so it is recommended to stock up on a screwdriver in advance. The next step is the throttle and choke drive cable. Both elements are removed quite simply. After that, dismantle the chip from the idle economizer. Dismantling is done very carefully so as not to damage the contacts. It's even easier to disassemble everything.

Recommended flow rate of pneumatic economizer nozzles for various operating conditions

You can now unscrew the four body nuts holding the carburetor to the intake manifold. If it is difficult to remove, then you can pick it up with a thick screwdriver. Hammer the manifold with a rag to prevent foreign particles from getting inside and clean the seating area from the remnants of the old carburetor gasket.

The carburetor itself consists of several elements:

• Top cover
• Bottom cover and float chamber
• Throttle valve block

First of all, the top cover is removed. At the same time, the condition of the needle valve and the condition of the float are checked. The valve should move without jamming and also easily return to its original position. You can immediately check the operation of the accelerator pump drive. All connections should be easy to twist. The principle of operation of many mechanisms is very simple, but they must stand exactly. It is configured after assembly.

Now you need to separate the throttle body from the bottom cover. Everything is held in place with bolts, so a screwdriver will suffice here. Once all the components are completely disassembled, they need to be treated with a throttle valve cleaner or regular gasoline. Parts must be wiped off with dry rags.

Nozzles deserve special attention. They need to be not only cleaned, but also blown out. The thing is that the jets have very thin channels that are easily clogged with foreign particles. Even one speck is enough to disable the entire unit. Disassembling and assembling the carburetor is half the battle. Now you need to carefully install and configure everything. The hoses are connected without sealant.

Installation and assembly of the carburetor VAZ 2109

After cleaning all the elements, you can assemble it. Check the clearances in the throttle valve block in advance and set them to their nominal values. For each type of unit, you can find all the calibration data in the reference books. Instead of old gaskets, it is recommended to immediately install new ones to avoid re-disassembly after two weeks of operation. Installation of parts is done carefully.

Change the needle valve if required. A faulty valve can negatively affect fuel consumption, as it sinks and passes a huge amount of gasoline through the channel.

It is recommended to lubricate the damper actuators, levers and rods with a seledol or Litola 24. It is not recommended to use this lubricant in an environment that is in contact with gasoline. The grease is only suitable for external parts such as the plastic joints for the carburetor rods. They may or may not be standing.

Install the top cover last and only after adjusting the level in the float chamber.

Float chamber diagram with installation parameters: 1 - float; 2 - tongue; 3 - gasket; 4 - cover.

The level in the float chamber is necessary for the smooth operation of the carburetor. Too high a level contributes to an increase in fuel supply, and an insufficient level will reduce the throttle response of the carburetor engine, since the level will not be able to pick up on time.

To adjust the level in the chamber, turn the top cover over and bend the float as far as the antennae allow. The distance between the bottom corner and the cover must be 20 mm. If not, bend the tendrils and replace the top cover. Such a do-it-yourself adjustment of the VAZ 2109 carburetor is considered nominal. The principle of action is simple here.

Air damper or starter control

Install the carb, but do not install the air filter. Pull out the choke completely and close the flap. In this position, you need to adjust the air damper drive cable.

Try pulling and removing the choke several times. The damper must open and close completely without jamming. If everything is done correctly, you can install the air filter in place, connect all hoses and the carburetor drive. It's time to start adjusting the idle speed of the VAZ 2109. Do not forget about connecting the EPHH.

How to set up the correct carburetor on a VAZ 2109?

The rated speed on the VAZ 2109 engine must correspond to 750-800 rpm. Adjustment of the XX carburetor is necessary to economically maintain engine operation while stationary and to warm up as soon as possible before driving. Without this, the device will not work. Table from those. characteristics of the carburetor does not have such data. This must be done in accordance with the following instructions, which contains the XX norm. The results and the adjustment scheme are stable rpm.

This procedure is performed if there are problems with the engine or every six months in accordance with the regulations on the maintenance of the VAZ 2109. It takes only 3-4 minutes to spend on it. The engine warms up to operating temperature by suction or using the accelerator pedal. Next, we remove the suction and completely tighten the quality screw. Most likely, the engine will stall. Now the screw is unscrewed exactly three turns and the motor starts again.

With the help of the adjusting screw for the quantity, it sets the speed of 650-700 rpm. Now rotate the quality screw until the maximum possible idle speed is obtained. Again, we set the number of revolutions equal to the nominal. Now you need to rotate the quality again until we get the maximum speed. It can take a long time to regulate.

Conclusion

If, after adjustment, there are dips when pressing the gas pedal, then slightly unscrew the amount screw to enrich the mixture. Most likely, the revs will increase slightly, but should not exceed 900 rpm. Do-it-yourself adjustment and tuning of the carburetor on a VAZ 2109 car is completed.

A more accurate carburetor setting is made using a special gas analyzer. Such a device allows not only to adjust the idling of the carburetor, but also to reduce harmful exhaust emissions. Thus, adjusting the carburetor can become environmentally friendly. But, more often than not, he is not there when he is needed. It is quite rare.

Carburetor installation and tuning can be done without an analyzer. The connection of the device is tight.

This is how the carburetor of the VAZ 2109 is adjusted. We hope that this article helped the readers answer the question of interest - how to adjust the carburetor on the VAZ 2109 correctly. We wish you good luck on the road and I will once hear your opinion on the article in the comments, maybe there are some edits!

Most of the VAZ cars of the Samara family, and in particular the VAZ-2109, came off the assembly line with a carburetor power system, and only later a small series received injectors. The carburetor system has a simple design and is quite reliable, but its main component, the carburetor, requires periodic adjustment. VAZ-2109 and other models of the family were equipped with Solex carburetors, which are distinguished by a relatively simple technology of adjustments that can be performed by every motorist.

There are two main carburetor settings - the fuel level in the float chambers and the engine idle speed (XX). These adjustments are carried out with and even with the manifestation of certain symptoms of malfunctioning of the power system:

1. The dynamics of acceleration has decreased.

These problems indicate that the fuel level in the chamber is abnormal.

Setting the fuel level

Adjusting the amount of fuel in the chambers of Solex carburetors is a simple procedure and does not require specialized equipment. Although in the factory, this adjustment is performed using a special template, which simplifies and speeds up the work. But at home, you can do without this template.
To independently perform adjustment work, you need:

• screwdrivers (Phillips, flat);
• ruler (better than a caliper);
• a round bar with a diameter of 2 mm (a wire or drill is suitable).

All work can be done quickly with this equipment.

Level control technology includes a number of steps:

In the case when the amount of fuel in the chamber is below or above the norm, we carry out a visual inspection and a number of measurements on the floats, if necessary, we correct their position.

To carry out adjustment work, put the removed carburetor cover on a flat horizontal surface with the floats up.

First, we look from above at the position of the elements. The outer side surfaces of the floats are parallel to the special imprints on the gasket. Deviations can cause the floats to touch against adjacent elements and surfaces, as a result of which the fuel level is not correct. If necessary, we adjust the position of the floats by bending their fastening levers.
The next step is to measure the gap between the floats and the gasket. A rod with a diameter of 2 mm will come in handy here - this should be the specified gap.

If it does not correspond, we bend the tongue of the floats, with which they act on the shut-off needle. After this adjustment, we check the total height of the floats, which is normally 34 mm. If this is not the case, check the gap again, correct it if necessary and measure the height again.

The last step in the setup is to define the working stroke of the floats. To do this, we put a caliper near the float, mark the distance from its lower corner to the surface of the lid, then raise the float with our hand and mark where the lower corner is.

A working stroke of 15 mm is considered normal, if it is different, it is adjustable by bending the tongue.

Alternative way

There is an easier method for determining the correct position of the floats, which does not require measurements.
Place the carburetor cover on a flat table and look at the punches made on the side surfaces. When the floats are in the normal position, these strips are parallel to the cover.

Then we lift the floats up and look at their bottom, which, after lifting, should be located parallel to the surface of the lid. If necessary, adjust the position of the floats by bending the tongue.

After adjustment work, we assemble the carburetor.

Idle speed adjustment

The second setting of the VAZ-2109 carburetor is idle speed, it can be partial and full. The first is for minor adjustments to the rpm, the second is with air volume control (setting of CO emissions in exhaust gases).

Partial adjustments are made with the air-fuel ratio screw. This screw sets the opening angle of the throttle valves, which ensures the flow of the air-fuel mixture into the cylinders when the accelerator pedal is released. The “quantity” screw rests against the throttle valve control lever and when screwed in, it pushes the lever, which causes the flaps to open slightly.

Partial is performed on a warmed-up engine and with the creation of a load on the on-board network of the car, by turning on the high beam of the headlights and the interior heater at full power.
The adjustment is carried out on a running engine by screwing in / out the "quantity" screw until the optimum idle speed is established, which for the VAZ-2109 is 800-900 rpm (this can be tracked by a standard or connected tachometer).

If it is not possible to set the required revolutions or the motor is unstable at them, a complete adjustment is carried out, which is carried out by two screws - "quantity" and "quality".

The algorithm for this adjustment consists of the following stages:

1. We warm up the engine, then turn off;
2. We find the quality screw (it can be closed with a plug that will have to be removed), turn it all the way, and then unscrew it by 3-4 full turns;
3. We start the engine, turn on the electrical consumers (lighting and stove) to create a load in the on-board network;
4. Rotating the “quantity” screw, we achieve 700-800 rpm on the tachometer;
5. Turning the "quality" screw, set the maximum possible revolutions (they will increase to a certain level, and then they will stop. The moment of stopping the increase in revolutions is considered the maximum);
6. We expose with the screw the "quantity" 900 rpm;
7. With the "quality" screw we lower them to 800 rpm;
8. Slowly turn the “quality” screw until the power plant malfunctions, after which we turn it back 1 turn;
9. We correct the revolutions with the "quantity" screw, bringing them to the normal level - 800-900 rpm;

After adjusting operations, we check the correctness of their implementation. This is done by abruptly pressing the gas pedal followed by a quick release. With a properly tuned carburetor, the engine should respond quickly to pressure, without any dips or hiccups. And after releasing the pedal to the idle level, without subsidence or the manifestation of instability of the motor.

Adjusting the VAZ carburetor for front-wheel drive car models is reduced not only to adjusting the idle speed, although this is the main type of adjustment. On the Samara family (Sputnik), DAAZ carburetors of the Solex type were installed. A feature of the Solex carburetor is that its design is practically unchanged on various car models, and the necessary characteristics for preparing the fuel-air mixture are achieved by using sets of diffusers and jets of certain sizes, depending on the working volume of the gasoline engine. In other words, adjusting the VAZ-2108 carburetor is performed in the same way as adjusting the VAZ-21093 carburetor.

Unlike the Ozone carburetor in Solex, the connection between the throttle valves of the first and second chambers is not gas-dynamic, but mechanical with the help of traction. Another feature of Solex is that the idle system is conventional, and not autonomous, as in Ozone. Therefore, when adjusting the VAZ-21083 carburetor, the screw for the amount of the mixture actually opens the throttle valve of the first chamber. If your "nine" required adjustment of the VAZ-2109 carburetor, then it is best to entrust this work to specialists who will do it with the help of a gas analyzer.

In Ryazan there are many service stations that adjust carburetors.

On the other hand, adjusting the VAZ Solex carburetor is within the power of a motorist who is familiar with the device of this unit and has certain ideas about the principle of its operation. As mentioned above, the main type of adjustment of the VAZ-21099 carburetor, for example, is to adjust the stable operation of the engine at idle with a minimum content of CO in the exhaust gases.

Carburetor adjustment work should be started only if the gas distribution mechanism and ignition system are in good working order. Naturally, the carburetor itself must be serviceable and all adjustments must be made in it, including the accelerator pump set up.

The video by Evgeny Travnikov clearly shows the adjustment and small "tuning" of the accelerator pump.

For beginners, to understand the principle of operation of the Solex carburetor, another video by Evgeny Travnikov will be useful.

You should not use all kinds of components not recommended by the manufacturer for an apparent improvement in the carburetor operation. It is not necessary to screw in the jets from the VAZ-21213 carburetor when setting up and adjusting the VAZ-2110 carburetor - nothing good will come of it.

This is what Evgeny Travnikov talks about in the next video.

For many car enthusiasts, cleaning the carburetor is a serious problem that they hesitate to tackle on their own. The same can be said for carburetor adjustments.

Another video from Evgeny Travnikov "on the fingers" shows how to do it.

which carburetor is better put on vase 2109

Nine. almost the most popular car in the Russian car industry. Simple, smart enough and adequate for the price, it has become a tasty morsel for not too wealthy car enthusiasts. In principle, despite all the complaints about VAZ and some skepticism of the population, the car was perceived well enough and is still being bought. Moreover, not only its modifications are VAZ 21093 and others, but also the original nine in the classic layout. But, like all domestic equipment, this car had a number of technical shortcomings.

And one of the problems associated with filling the VAZ was carburetor for drivers. The point is not that it turned out frankly worse than its colleagues installed on other cars of the Lada family, but there were no shortcomings without the traditional ones for our cars. Basically, nine are not the most complicated domestic machines in operation and repair, and they are easy to set up, so
has recently become very popular in Russia.

The ninth model, officially named Lada Samara, received several types of carburetor engines. The standard Lada received a 1.3-liter four-cylinder carburetor engine. E of the senior team on the VAZ 21093 model line received a VAZ-21083 engine. As a result, they appeared on nines. Carburetor for VAZ 2109 , familiar to car owners, does not have complex functions. The model is two-chamber, emulsion.

As if someone did not scold the assembly of the VAZ, it has advantages, not just disadvantages. At least due to their simplicity and mass character, VAZs are so popular in our country that the plant itself survived the crisis and still produces cars that are still in demand among the population to this day. Very popular today. Standard carburetor VAZ 2109, or rather a mock-up of the device, which you can see below. As we can see in this diagram (view from the throttle body), the VAZ 2109 carburetor device is quite simple.

It is not much more difficult to recover under standard conditions. That cannot be said about the complexity of working with the injector at the same time. When the plant in Togliatti began to produce the VAZ car 2109 carburetor, he chose the tried and true enough. When it comes to tuning, this is clear in these carburetors.

Our readers often ask which carburetor is better. put for a VAZ 2109? It is difficult to answer this question unambiguously. But let's think about it. From what the market offers, the most famous are Solex, Weber and DAAZ. The first is perhaps the most common. The second is difficult to install, but excellent in quality.

And with the third, how lucky. On the VAZ 21093, most often Weber 40 DCOE 151 carburetors. Among the owners of the Lada Samara of this model, it is believed that the Weber model is better.

It is difficult to judge how right these or those VAZ owners are, because any carburetors break down. And, as practice shows, seasoned webpers sometimes do not find spare parts, while less complex Solexes compare favorably in this regard. As the mechanics say, the life of a simple mechanic is complex and uncomplicated. Carburettors are far from the best. Especially when it comes to the repair of domestic automotive equipment.

Disassembling, cleaning and washing the carburetor since nine. this is another headache. Especially when you have to carry out these procedures in the field, and not in a cozy and hot box. It's hard to blame VAZ, it's the prices for spare parts.

Here they are much more profitable than most competitors. Take at least such a moment as the price of a VAZ 2109 carburetor. This spare part for a VAZ 2109 car is much less than in the case of most foreign cars.

Retail price of the carburetor VAZ 2109 ranges from 3 to 5 thousand rubles. Some car owners choose such a service as tuning the VAZ 2109 carburetor. It is difficult to say how much this service is in demand now. But sporty carburetor put people. Of course, to increase the power of the VAZ 2109 engine, the sports type of the carburetor affects. But how much this is justified in urban conditions, especially in Russia, it is difficult to say.
