VAZ 2109 carburetor tuning is a popular and very popular topic lately. From the article we will learn how to do it.
On the VAZ 2109, tuning a Solex carburetor or a carburetor of another production is carried out for only one main reason - to increase power and dynamic characteristics auto.
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.
Refinement of 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 carburetors are devices that are designed to accurately dispense fuel into an air stream.
The Solex carburetor is also distinguished by 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. For the passage of air in the lower part of each chamber, a throttle valve is provided.

• Due to the fact that there are two chambers, and the damper drive is designed so that as you pull on the gas pedal, one and then another channel opens, such a carburetor is called a two-chamber.

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

• Of the main features of the carburetor, we also note cone-shaped narrowings, called diffusers. They are needed in order to create the vacuum necessary to suck fuel from the float chamber (a special container in the carburetor body).

Note. The fuel level in the float chamber is constantly maintained to ensure the normal operation of the carburetor.

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

Classic tuning

To carry out tuning of the Solex carburetor, it is necessary to carry out the following operations:

• dismantle itself;
• It is good to clean it from dirt;
• Remove jets and throttle valves (carried out for boring diffusers);
• Both cameras must be increased in size on a special machine;
• Grind the carburetor to reduce incoming air resistance;
• We select the ones necessary 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 VZH must be selected so as to pass a certain amount of air, which would be equal to the amount of fuel passed through the TJ. Otherwise, the fuel mixture will not be properly balanced, which will inevitably lead to weak acceleration and other problems.
In addition, the jets must be properly balanced. It is necessary to approach this issue with all responsibility, understanding that the instability of the fuel level will lead to a lean mixture.

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

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

Two carburetors instead of one

This approach is also considered as effective tuning. This idea has a very sound basis. It would seem why the engineers themselves did not think of this at the design stage of the VAZ 2109 car, but that's another story.

Note. One of the main reasons for installing two carburetors instead of one, experts and tuners see that due to the oddities of designing on power unit"nines" different lengths of the collector 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 manifolds and both chambers from the inside. This procedure will allow more mixture to enter the chambers, as a result of which the resistance to flow will drop, the quality will improve, and everything will become much more efficient.
But, nevertheless, this is not an ideal option - installing two carburetors instead of one looks much more attractive.

Important Points

Here are some important points to consider when installing:

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

Note. Adjustment of carburetors can be carried out using a bar of vacuum gauges or an IKS-1 mixture quality sensor screwed in place of the candle. So that the adjustment is correct, it is necessary to idling observe the color of the mixture and achieve that it becomes light blue.

Do-it-yourself installation algorithm

Here's what to do:

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

Note. You can install two carburetors on the “nine” without mounting the adapter, but then you will have to cut, connect, etc. a lot.

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

Advice. As a damper drive, it is desirable to use traction from Ozone, but not cables from Tavria, which are stretched.

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

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

Tuning is a responsible, but entertaining process. Before using 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.

which carburetor is better put on a vase 2109

Nine. almost the most popular car of the Russian automobile industry. Simple, fairly neat and adequate price, it has become a tasty morsel for not-too-wealthy motorists. In principle, despite all the claims against VAZ and some skepticism of the population, the car was perceived quite well and is still being bought. Moreover, not only its modifications 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. It's not that it turned out frankly worse than its colleagues installed on other cars of the Lada family, but there were no drawbacks traditional for our cars. In principle, nine in operation and repair are not the most difficult domestic machines, 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 senior team on model line VAZ 21093 received the VAZ-21083 engine. As a result, the nines appeared. Carburetor for VAZ 2109 , familiar to car owners, does not have complex functions. Model two-chamber, emulsion.

As if no one scolded the assembly of the VAZ, it has advantages, and 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 the layout 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.

Today Nail Poroshin will tell and show the main nuances of the installation of the 53rd carburetor to the Classic! Everyone.

It's not much harder to recover under standard conditions. What can not be said about the complexity of working with the injector in this case. When the plant in Togliatti began to produce a VAZ car 2109 carburetor, he chose a proven and quite nagzhny. As for the setting, everything is clear with this in these carburetors.

Our readers often ask which carburetor is better. put on VAZ 2109? It is difficult to answer this question unambiguously. But let's think about it. Of 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 it is excellent in quality.

And with the third how lucky. On VAZ 21093, most often Weber 40 DCOE 151 carburetors. Among Lada owners Samara of this model believe 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, singing webpers sometimes do not find spare parts, while less complex Solexes compare favorably in this regard. As the mechanics say, life simple mechanic complex and uncomplicated. Carburettors are far from the best. Especially when it comes to the repair of domestic automotive equipment.

Dismantling, cleaning and washing the carburetor from 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 in 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 replacement part for a VAZ 2109 car, it is much less than in the case of most foreign cars.

Retail price of a VAZ carburetor 2109 ranges from 3 to 5 thousand rubles. Some car owners choose a service such as tuning a 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 carburetor affects. But how justified this is in the conditions of the city, especially in Russia, it is difficult to say.

The carburetor is sometimes called the heart of the engine in the sense that it depends on its proper operation whether the car will come to life, that is, the car will start or not. For the family of cars 2108, 2109, 21099, 2110, this analogy is of particular importance: here the comparison is also justified because the Solex modification carburetor used in these brands of cars is to some extent similar to a heart in its structure - it has two chambers .

If we take the developed Western world, then carburetors were widespread there only until the 80s of the last century, when they began to be replaced by single injection, and subsequently by injectors. Photo: autobrains.ru

What role does the carburetor play

As is known from the course of chemistry, not only fuel, but also oxygen is involved in the combustion process. In the absence of oxygen, the combustion process cannot take place. For the operation of an internal combustion engine, a mixture consisting of vapors or small drops of gasoline and atmospheric air must be supplied to it. This function is performed by the carburetor. As a device, it belongs to the engine power system, it prepares the gas-air mixture and supplies it to the engine, and also allows you to control this process from the outside. The carburetor specifically VAZ 2109 consists of a number of systems that provide the following engine operating modes:

• launch mode;
• idling;
• overclocking mode;
• economical mode, which consists in blocking the supply of the mixture when driving at forced idle.

In addition, the carburetor of the VAZ 2109 car has some technical elements that provide acceleration dynamics.

The role of the VAZ 2109 carburetor is not just to prepare some strictly defined mixture, but to prepare for each engine operating mode optimal composition fuel mixture.

For example, for the start mode, a re-enriched mixture is required, that is, with a significant predominance of gasoline over air, and during idle operation, much less fuel is required.

How the VAZ 2109 carburetor works

According to its internal structure, the carburetor is a combination of several devices that prepare the fuel mixture for different modes, that is, it is, as it were, several carburetors combined into one. Photo: media.karelia.pro

In addition to units designed directly for carburation, it includes:

• Mesh filter for after-treatment of fuel;
• Accelerator pump;
• Forced economizer idle move;
• Economizer of power modes;
• Ecostat.

The principle of operation for each mode can be traced by observing the passage of gasoline. When you gently press the accelerator, gasoline from the float tank enters the emulsion well. Its path begins with the main fuel jet with a cross section of about 1 mm. It limits or, in other words, doses the flow. From it, gasoline goes to an emulsion tube that acts as an air jet. Such a tube, due to perforation in the walls, enriches gasoline with air. The gas-air mixture goes to the atomizer of the main dosing system, mounted on top of the diffuser chamber.

The operation of this entire mode is based on the vacuum created in the cylinders: when the throttle is turned, controlled by the accelerator pedal, the vacuum sucks the mixture into the cylinders.

The same processes take place in the second chamber, the damper of which opens when the accelerator is pressed deeper. While it is closed, fuel will not be supplied to the second chamber.

Fuel in idle mode (XX) also comes from the main jet of the first chamber, but it bypasses the diffuser chamber. The selected fuel enters the jet XX, which is blocked by a solenoid valve, then mixes with air supplied by the air jet XX. The resulting emulsion exits just below the throttle valve. The circulation of gasoline in this mode is provided by a diaphragm pump.

A sharp press on the accelerator pedal turns on the accelerator pump, a portion of fuel from which shoots in a thin stream through a tube (nose or so-called “proboscis”) directed into the diffuse chamber directly into the collector channels past the slightly open throttle. The accelerator pump has two such proboscis at once, directed to both chambers.

The carburetor mainly works on the first chamber, the second comes into operation at high speeds. The speed is controlled by the angle of the throttle valve - when it is turned, the pressure ratio between the diffuse chamber and the intake manifold changes.

A rich mixture is also used when starting a cold engine, when the choke handle is pulled out to control the throttle angle. Thus, it is fixed at a certain angle.

Depending on the required working power, the following additional devices are included in the operation of the carburetor:

• Forced idle economizer. During engine braking, this economizer monitors RPM and cuts off fuel if the following conditions are met: gear engaged (coasting), accelerator released, RPM above idle threshold. The supply is resumed when the speed drops to the corresponding idle speed.
• Economizer of power modes. It takes fuel into the emulsion well bypassing the main jet.
• Ecostat. Turns on when the engine needs maximum power. Takes fuel directly from the float chamber and delivers it directly to the second diffusion chamber.

Why adjust the carburetor

Whether your car will run depends on how the carburetor prepares the mixture. It is characterized by the percentage of gasoline and air. The stability of the engine will depend on how correctly this ratio is set. In addition, fuel economy depends on it.

Typical malfunctions associated with misalignment of the carburetor:

• low idle speed. When you release your foot from the gas pedal, the engine stalls;
• dieseling - in the absence of ignition, the engine, on the contrary, does not stall;
• failure in the set of revolutions;
• jerking, twitching when moving.

How to adjust the carburetor with your own hands

A new factory carburetor will usually already be adjusted, but the fuel level in the float chamber may require adjustment. This is due to the fact that the parameters fuel pump individual for each car. This is done with a needle valve.

On the new device, the throttle control actuator cannot be adjusted in any way - the length of the cable is different everywhere. Therefore, such an adjustment is only done when installed on a car. With the accelerator pedal depressed, both throttle valves should be open, and with the accelerator pedal released, they should be closed.

This procedure is carried out only on a warm engine.

Idling is set by the so-called “quantity screw” - with its help, the angle of rotation of the throttle valve of the first diffusion chamber changes.

You can find a video guide to adjusting here:

Outcome

Although the device has two chambers combined with the manifold, in practice only the first chamber operates at moderate speeds, the second chamber flap opens only when the accelerator pedal is pressed deeply. This circumstance is perceived by some craftsmen as an opportunity for optimization. In order to save fuel, sometimes they even muffle the shutter of the second chamber.

You can also find a recommendation for bending the proboscis of the acceleration pump into the first chamber. All these interventions are absolutely impossible to do. These measures are not provided for by the plant, and when tested at the stand, they show that in fact they have the opposite effect: they increase fuel consumption and increase the toxicity of exhaust gases.

And in order to avoid problems with the carburetor as long as possible, it is required timely replacement air filter. As practice shows, it is he who is the main source of blockages in the fuel jets.

Domestic cars VAZ-2109 are equipped with a reliable and maintainable Solex carburetor. The device has proven itself to be quite reliable, but to ensure a long period of operation it is necessary to constantly clean and adjust it. Malfunctioning parts can lead to excessive fuel consumption and serious engine damage. Adjustment of the VAZ-2109 carburetor can be carried out independently at home with a set of tools.

Signs of a broken carburetor

The carburetor, like the rest of the engine, plays a big role in the movement of the car. Assembly malfunctions are manifested first by unpleasant symptoms, and only then lead to serious disturbances in the operation of the motor. The first signs that you should pay attention to are the following manifestations.

1. Pedal dips. When you press the gas pedal, the car travels at the same speed for a while and only after a few seconds does it start accelerating. Sometimes the interval can reach up to 10 - 20 seconds, and then ignoring it becomes unsafe.
2. dash. A sharp set and slowdown may indicate a malfunction of the carburetor. Usually, jerks are very short-lived, so they can be confused with signs of malfunctions in other parts.
3. twitching. A series of jerks, which is repeated at some interval, indicates a problem in the carburetor.
4. rocking. The failures following one after another lead to the fact that a swaying effect is created.
5. Slow acceleration. If the car has become much slower to accelerate, and there are no obvious reasons for this, then it is worth adjusting the VAZ-2109 Solex carburetor.

Although all these signs are highly likely to indicate a breakdown of the carburetor, sometimes there may be situations in which characteristics malfunctions become uninformative.

In non-standard cases, it is necessary to conduct a comprehensive diagnosis.

How to set up a carburetor on a VAZ-2109 Solex with your own hands

Initially, you need to prepare the entire tool for adjusting and repairing the carburetor. Tuning is often accompanied by small repair work, so the masters recommend having the whole essential tool. In the room in which the mechanism will be disassembled, it is necessary to ensure good ventilation, as strong fuel vapors can lead to a deterioration in well-being.

In the process of work, you can not use rags or brushes, so you should prepare in advance a special material that does not crumble and does not change its structure.

For convenience and high-quality results, the car must be on a horizontal plane. A flathead screwdriver should always be nearby, as it is used most often when setting up a carburetor. Cleaning of the part must be carried out with special means or, in extreme cases, with clean gasoline.

The float chamber regulates the fuel level. This part of the device is the easiest to repair and set up, so it is better for novice craftsmen or motorists to start from this point. Do-it-yourself adjustment of the VAZ-2109 carburetor consists of several stages:

1. It is necessary to start the engine and let it run for 2 - 3 minutes.
2. After the engine has been turned off, it is necessary to remove air filter from Solex.
3. Next, disconnect the fuel hose.
4. When dismantling the carburetor cover, you need to unscrew 5 hardware. A feature of the dismantling of the bolts is the need to unscrew them strictly vertically. If the hardware is removed incorrectly, the floats can be damaged, which will cause serious repairs.
5. Normally, the distance from the edge of the carburetor to gasoline is 25.5 millimeters. If the distance does not match, then you need to correct it by bending the tongue of the float bracket. Since it is difficult to set the desired distance the first time, the bending procedure can be repeated several times.
6. While the cover is removed, experts recommend checking it for parallel edges and, if necessary, restoring the correct position of the elements.

On the "nine" these works are quite easy to carry out.

One of the main conditions is the constant maintenance of cleanliness and the prevention of various small parts entering the carburetor.

The starting device can be configured in the removed state. Before adjustment, it is necessary to check the condition of the diaphragm. The part breaks down quite often, so it must be replaced with a new one immediately after deformations are detected. Setting starting device takes place in five stages:

1. Closing the air damper. To do this, turn the drive lever.
2. Changing the location of the stem. Using a screwdriver or other object, the starter rod is recessed for the duration of the adjustment work.
3. Gap measurement. After drowning the stem, the damper opens slightly. It is necessary to measure the distance between the damper and the chamber wall. The indicators are compared with the parameters declared by the manufacturer and, if necessary, adjustments are made.
4. Trigger setting. If there is a discrepancy in the size of the gaps, adjustment is carried out. To do this, turn the screw with a screwdriver. The screw, when unscrewing, provides an increase in the gap, and when screwing in, it decreases.
5. Throttle chamber clearance. air damper be sure to close tightly. The gap dimensions are indicated in the manual, which simplifies the process of adjusting the position of the throttle chamber. Adjustment is also made using a hardware.

Stroke adjustment is carried out on a fully assembled system. The engine must be well warmed up before adjusting the idle speed. It is better to use a tachometer and a gas analyzer when adjusting, but you can do without the latter. Adjustment without a gas analyzer is carried out according to the following scheme.

1. With the engine off, it is necessary to screw in the hardware of the quality of the air-fuel mixture until it stops.
2. Next, you need to do 3 - 4 turns in the opposite direction.
3. The engine must be started, the suction removed, the fan and high beam turned on.
4. With the fuel quantity screw, it is necessary to bring the engine speed to a value of 750 - 800 rpm.
5. The quality screw must be set to maximum speed.
6. The quantity screw must be set to 900 rpm.
7. Further, using the quality screw, the speed must be reduced to 800.
8. The quality screw must be tightened until the motor starts to work unstably. After the revolutions begin to float, it is necessary to turn the screw one or half a turn back.
9. The quantity screw must be set to the required speed. For summer, the indicator is in the range of 800 - 900 rpm, for winter 900 - 1000 rpm.

VAZ 20109 is the most massive model of the first generation of AvtoVAZ front-wheel drive cars. Periodically, its various modifications appeared on the market. One of them was option 21093. For the modification of the VAZ 21093, the technical characteristics were very good for both engine options: carburetor and injection.

Place 21093 in the line of AvtoVAZ models

The prototype for the VAZ 21093 was the front-wheel drive hatchback VAZ 2109 Sputnik, with carbureted engine with a volume of 1.3 liters, produced in Togliatti since 1987. The power of its engine was 64 horsepower. Outwardly, 21093 "Samara", which appeared in 1990, was not much different from 2109. Dimensions, design, decoration - everything was almost like the nine. The main differences were hidden under the hood.

Modification 21093 received new engine. The designers of the Volga Automobile Plant increased the cylinder diameter from 78 to 82 mm with the same piston stroke of 71 mm. This gave an increase in working volume from 1288 cubic cm to 1499. The car has increased power, improved performance (speed and acceleration dynamics), and slightly decreased fuel consumption. In general, the VAZ 21093 car acquired a noticeable liveliness.

VAZ 21093 "Samara" was produced in Togliatti until 2004, giving way to model 2114, a five-door front-wheel drive hatchback from the Samara-2 family.

Body and interior VAZ 21093

Over the years of the release of modification 21093, there have been some changes in design while maintaining the dimensions of the body. The body of the ninety-third is a five-door hatchback, its front end and radiator have been updated, a short wing has appeared. Overall and inner dimensions models 2109 and 21093 match to the millimeter. The interior of the car 21093 is five-seater, but it is difficult for three large men to fit in the back. The rear row of seats folds down, almost doubling the volume of the trunk (from 330 liters to 640 liters).

The main dimensions of the car "Lada 21093".

The deluxe package had an improved dashboard with tachometer and on-board computer, it was possible to install electric windows and an anti-theft system. For upholstery and seats, several options were offered: from the most unpretentious gray textiles to colored materials more High Quality. The cabin of the ninety-three was comfortable and practical for both daily commuting and relatively long trips with children.

With regard to the body and interior of the VAZ 21093, tuning is quite possible. Experienced motorists often do tuning with their own hands.

93rd engine options

There are two engine options for model 21093:

• carburetor VAZ 21083;
• injection VAZ 2111.

Both engines are in-line, four-cylinder, eight-valve and have a working volume of 1499 cm3. The motors are located transversely in front. The cylinder diameter and piston stroke are the same, and the compression ratio is 9.9. Engines consume gasoline: carburetor - AI-93, injection - AI-95. Capacity fuel tank the same - 43 l.

The VAZ 21083 engine on the VAZ 21093 model, the carburetor develops a maximum power of 70 Horse power at 5600 rpm, and the torque is 104 Nm at 3400 rpm. Max Speed- 154 km / h, the engine accelerates the car to 100 km / h in 13.4 s. Fuel consumption VAZ 21093 per 100 km in the city - 8 liters, outside the city - 5.7 liters, in the combined cycle - 6.8 liters. The curb weight in this case is 915 kg.

In 1994, a version of the VAZ 21093 injector was released, which received the designation VAZ 21093i. Specifications VAZ 21093i changed to better side. Engine power increased to 78 horsepower at 5400 rpm, torque was 116 Nm at 3000 rpm. Acceleration time to 100 km decreased to 13 s. Now about how much the car eats. Fuel consumption in the city is equal to 9 liters per 100 km, outside the city - to 5.9 liters, in the combined cycle - to 7.2 liters. The curb weight is 945 kg.

Transmission and running car VAZ 21093

The transmission on the VAZ 21093 is structurally made by one unit, including the clutch and mechanical box gear shifting (manual transmission). The box is combined with a differential, the clutch is single-plate. The clutch cover is bolted to the flywheel. To ensure contact with the pressure plate are six elastic plates. The gearbox is mechanical, five-speed. The gears of the input shaft are constantly engaged with the driven gears. The output shaft has two synchronizers.

The car wheel drive includes two constant velocity joints (CV joints): a bar shaft on the left and a tubular one on the right. The front suspension of the car is independent, shock absorbers are hydraulic, springs are cylindrical. Rear suspension torsion-lever, independent, with trailing arm design.

The braking system on the Model 21093 uses disc front and drum rear brakes. There is a diagonal interaction of the contours. One circuit includes the right front and left rear wheels, the other - the remaining two. The hydraulic drive of the system includes a vacuum booster and a rear brake pressure regulator.
