The choice of carburetor for the "classics" VAZ. Installing the carburetor "Solex" on the classics how to get maximum benefits

Various modifications of VAZ-2107 carburetors were installed on certain models, namely:

2107-1107010-20 series devices have completed engines of recent versions on VAZ-2103 and, which are equipped with vacuum-corrector;

modifications of products 2107-1107010 was established on force units 2103 (2106) VAZ-2107 cars and VAZ-2105;

2107-1107010-10 series carburetors were used on motors 2106 and 2103, which are equipped with a ignition distributor without vacuum proofreaders.

A two-chamber modification carburetor 2107-1107010 is made by the type of emulsion device with a falling flow. It is equipped with a balanced by a float chamber, a processing device, two main metering systems, a mechanism of compatible gas suction mechanism, a special nozzle of feeding to a vacuum controller, an autonomous XX (idle) system and other necessary elements. Position Management, namely, the discovery of DZ () of the camera is implemented through the drive pedal installed in the cabin. DZ of the second chamber is controlled by a special pneumatic drive.

Equipped with a starting diaphragm mechanism for starting XX. The accelerator pump is made by a diaphragm device equipped with a mechanical drive. It provides fuel to the chamber. Fastening the carburetor is implemented through four stiletto tube pipes.

How to adjust the carburetor on the VAZ

Adjusting any modification, including configuration of the VAZ-2107 carburetor, is carried out on the basis of the target parameters in which all the necessary data are laid. Experts recommend setting up 1 time in 6 months. In fact, this procedure is the planned maintenance of this device.

The setting of the carburetor 2107-1107010 includes the following operations:

cleaning and car wash outside;

monitoring the state of mechanisms and individual elements;

flushing (cleaning) of the mesh filter;

flushing (cleaning) of the float chamber;

flushing (cleaning) of fuel and air jets.

Describes in detail all stages of setting up the 2107-1107010 series devices, as cleaning or washing, as well as the disassembly of the VAZ-2107 carburetor is identical for all modifications. Therefore, we consider only the most important points.

Video for setting up carburetor Solex on VAZ-2107

To monitor, and if necessary, set up a given gasoline level in a PC (float chamber), you must first prepare a special target pattern with a size of 6.5 x 14.0 mm from cardboard.

First, we carefully remove the lid of the carburetor and put it vertically in such a way that the float lever does not give it, but only rushed the ball of the loaded valve. Under the float, we put the template and control the gap between it and the cover of the lid. If there is no template, it is possible to measure the calipers or a conventional ruler. The size of the gap should be within 6.25-6.75 mm.

If the distance from the float to the laying of the cover does not correspond to the specified value, it should be adjusted by it by cautiously beyond the IR holder (needle valve).

The next step is set up the maximum opening of the IR, which is determined by the flow of the float. To do this, carefully move the float from the cover body and measure the distance of the template or ruler (caliper). The permissible range for this parameter is 13.5-14.5 mm. If the magnitude of the gap you walk in the specified limits, we sweep the special stop located on the bracket, seeking the desired size.

If the setting of the carburetor is performed correctly, the location of the float will be 8 ± 0.25 mm.
Setting up
To proceed to the PU setup step (starter), pre-prepare a piece of wire with a cross section of 0.75 ± 0.05 mm and a cardboard (plastic) 5.0-5.5 mm wide width pattern. After that, dismantle the air filter and clean outside the carburetor.
1 is a three-meter air damper control lever; 2 - air damper; 3 - triggering device; 4 - rod; 5 - adjusting screw; 6 - throttle of the first chamber; 7 - throttle drive thrust
We close completely, with the end of the thrust, which connects the lever with the rod of the PU, should be at the end of the groove of this rod. Then we completely simply switch the rod and using a template or caliper (ruler) control the size of the gap between the chamber wall and the edge of the vz. It must be 5.0 + 0.5 mm.
Now set up the opening gap. Adjustment is performed using a special screw that is closed by a plug. Therefore, first, the slotted hole is unscrewed the plug, and then correct the opening of the PT.
Control opening DZ.
To perform this operation, you must first remove the carburetor. Then scroll the 3-shoulders lever counterclockwise and check the clearance with the help of the wire, the value of which should be in the range of 7.5 ± 0.5 mm. If necessary, carefully sweep the thrust or move its tip to another hole.
Setting up xx
To properly adjust the XX, a gas analyzer and multimeter will be required. Pre-warming the motor. Turns in XX mode should be within 860 ± 40 rpm. First configure the advance angle.
Multimeter We switch to the frequency measurement mode and connect one probe to the primary winding of the KZ (ignition coil), and the second we combine with the mass.
Sensor of the gas analyzer insert into the exhaust pipe and turn on the device.
If necessary, we correct the amount of quantity by the amount of the amount up to 860 ± 40 rpm.
The quality screw is achieved by the content of carbon dioxide in the range of 0.85 ± 0.35%. If you do not have a gas analyzer, control this parameter for stable engine operation.

When correctly configured, if you press and release the gas pedal, the motor should be smoothly increased, and then reduce the speed.
Adjusting the drive
After dismantling the air filter, we take the handle handle with my hands and move it from yourself so that the survey is vertically. If you cannot install vertically, proceed to adjust.
Using the key on 7, hold the sleeve and at the same time unscrew the screw of the valve thrust fastening. Under the action of the spring, the vc should become in a vertical position. Then tighten the screw.

Under the classic VAZ models should be understood by cars from 2101 to 2107. Owners of such cars with a carburetor are often resorted to the search for more efficient solutions to increase dynamic characteristics and / or reduction of fuel consumption. Both acceleration and efficiency are directly dependent on the carburetor model under the hood and from the quality of its adjustment. If the owner decides on the installation of a third-party carburetor, then you need to consider a number of individual features when choosing.

Staten models of carburetors

Various models of carburetors are focused on ecology, reduction of consumption or maximum car dynamics. Carburetors were also created for different volume engines. Some models of carburetors from one power unit can be easily installed on another, and in some cases alterations will be needed.

DAAZ Carburetor / Weber

DAAZ carburetors (Dmitrovsky Auto unit) 2101, 2103 and 2106 were products that were produced due to the license of WEBER. For this reason, the model is called both the DAAZ carburetor and the WEBER carburetor, but understand the same device. The specified models of carburetors are distinguished by the maximum simplicity of the design and provide excellent acceleration characteristics.

The disadvantages of these models rightly include high fuel consumption at the mark of 10-to 14 liters per hundred kilometers. Another potential complexity today is almost the complete absence of these models even used in acceptable working condition.

Carburetor Ozone

No less popular is the DAAZ 21053 carburetor model, which is the licensed products of SOLEX. The carburetor has established itself as economical and at the same time dynamic solution when installing "classics" on engines. The design of this model is very different from the previous carburetors DAAZ. The Solex carburetor has a fuel feed system (reverse). Due to this solution, the surplus of gasoline fall back to the benzobac. The return allows you to save about 400-800 grams of gasoline onto a hundred traveled kilometers.

Separate versions of this model can have a number of auxiliary electronic systems. The main solutions include a system of idling with an electric valve adjustment, an automatic cool start system, etc. Such innovations met on export versions of the car. In the CIS, the distribution was obtained by the Solex carburetor with an electrically controlled idling valve.

The system in operation was problematic. In the carburetor of this type, air and fuel channels are narrow and quickly clogged. If the carburetor cannot be serviced in a timely manner, then the initial stroke system fails. Carburetor Solex consumes from 6-to 10 liters of fuel in calm mode. As for the speakers, it is inferior only to the early development of Weber.

All the above-mentioned carburetors are put on the classic VAZ engines without refinement. The only nuance when choosing the selection of the carburetor relative to the working volume of your motor remains. In the event that the existing carburetor is designed for another volume, then the selection and replacement of jets will be required, as well as thorough adjustment of the carburetor.

Installing a non-standard carburetor

Owners of "Classics" in some cases resort to the installation of abnormal models of carburetors on their cars. Such an installation will require certain alterations and subsequent settings. It is about Solex 21073 and Solex 21083 carburetors models.

Model SOLEX 21073.

This model is designed for a motor with a volume of 1.7 liters and regularly installed on the power unit of the Niva car. The Solex 21073 carburetor differs from other large channels and giblars. Installing this model on other cars VAZ with a carburetor allows you to achieve an increase in dynamics, but fuel consumption rises to a mark of 9-12 liters per hundred.

Model SOLEX 21083.

Solex 21083 was put on the VAZ 2108-09. If you put it on the "classics" engines, then refinement will be needed. Gas distribution systems of motors 01-07 and 08-09 have a number of differences. The installation of such a carburetor without alteration will lead to the fact that with circulation about 4000, the speed of the air supplied can reach the sound, and the motor will not turn on to promotion. To install this carburetor model, it is necessary to reset the diffusers of the primary and secondary chamber for their expansion. You also need to install large jets. The process of refinement is laborious, but the result allows you to obtain gasoline consumption below the model 21053, and the speaker will exceed the indicators at 21073.

Summarize

Finally, add that there are models of foreign production carburetors. By cons of such a choice include high cost, complexity in setting up and maintenance, as well as not always better dynamics and economy is relatively listed above the DAAZ carburetors listed above the models, Solex or Weber.

What "Solex" pick up

The aggregates of production of the Dimitrovgrad Plant "Solex" differ mainly by the geometry of loans. There is a difference in diameters of diffusers, as well as in size, the design of air jets. Also distinguishes the cam profile.

However, without any unpleasant consequences and improvements, any of the "Solex" from the entire series can be put on a car for which the carburetor never has been manufactured. Models and modifications of these carburetors were produced many - they were equipped with VAZ-08, 09, AZLK-21412, ZAZ-1102. There are "Solex" for VAZ-2104, 05, 07. This all suggests that a completely any unit from the named line without alterations or almost without them can be placed on rear-wheel drive vases.

The result of tuning depends on the choice of concrete "solks". But in any case, the engine will improve the thrust, the car will get smooth overclocking. To save, it is worth choosing the "Solex" modification on "Tavria" - it is DAAZ-2181. If you need an enlarged acceleration dynamics, then the DAAZ-21073 is selected. It is distinguished by diffusers of larger diameter. This carburetor was created for motors with a volume of 1.7, and after installing this "Salex" to the classics should be prepared for large fuel consumption.

"Salexes" of models 2108, 21083, 21051-30 are considered to have a golden middle motorists. The aggregates are able to provide the best dynamic characteristics and less fuel consumption, if you compare their characteristics with Ozone.

Important little things

Any "Saleks" (except 21073) have beeters with very thin holes. It should be noted that because of this, the jackets are very sensitive to the Musor in the fuel, and the carburetor itself is often clogged with mud. Due to this, fuel filters should be changed regularly. To increase reliability, you can install an injection fuel filter. It will come out a bit more expensive, but it is possible to increase the interval between the revision of the unit.

If the decision to install the Solex carburetor to the classics is accepted, then besides the carburetor, additional spare parts may be needed. The unit can be installed with the recreatation of the EPHX system or without it - only an unconnected electromagnetic valve will remain. The easiest way to do with this system. But experts claim that EPHH even makes it possible to achieve 5% of fuel economy, but at the same time the system is unreliable and often fails. And this significantly reduces the reliability of the entire aggregate.

So that the electromagnetic valve cannot overlap the fuel supply to the idling channel of the "Salex" (after all, the EPHH unit is not installed), it is necessary to remove the valve needle from the case. But the easiest way to connect the valve from the ignition lock.

When installing the "Salex" on the rear-wheel drive vases, it is necessary to drain the "reverse" by the cork or connect it through the return valve into the fuel supply system to the fuel filter.

How to get maximum benefit

Little to install "Solex" to the classics to experience all the advantages, you need to upgrade the ignition system. Instead of a regular contactless ignition set. Any "Solex" is initially configured and designed to prepare to effectively ignite it, you need a more powerful discharge. The contact system of ignition cannot issue such a discharge, and contactless - quite. The coil of it can produce a voltage up to 25 thousand volts. Candle clearance will be not more than 0.8 mm.

New or used?

You can buy a new "Solex" to the classic, but there is an opportunity to purchase and used the carburetor. In the second case, it is necessary to conduct a revision to him - thoroughly clean the channels, polish the diffusers. In addition, it is better to purchase and replace the jets.

But at the same time it is not worth buying modern products - it is better to ask for friends and friends who were made in the USSR. Modern jets that are in repair kits often do not correspond to targeting sizes.

In order for the diffuser to work effectively, burrs and protrusions are removed from its elements. Such defects create air vigs, and this does not best affect the filling of cylinders.

What may take

First of all, it is necessary to purchase spare parts that will be needed during the installation of "Solex" on the VAZ of the classical model:

You should buy thin strips from the paronite. But you need them to be made precisely for "Saleks". Holes in the laying under diffusers differ from "Weber" and "Ozone".
Instead of two pads, you can purchase one, where two holes. It is put between a carburetor and a gasket from Ghetynaks. In addition, they take another one with an oval hole. It is designed to be installed between the collector and the Ghetinakse gasket.
Still acquire the "Furniture" hose. Its length should be at least 80 centimeters. Otherwise, it will not reach the fuel conductor under the pump.

Installation process

Now you can proceed to the installation:

To protect the collector from dirt from entering, the engine compartment is necessarily thoroughly clean.
Then from the standard carburetor disconnect drives and cables, as well as hoses.
To remove the casing of the air damper, on the "Supply panel" cleaned the bracket.
The surface of the collector is neatly cleaned, the sealant is applied.
After these operations, you need to install gaskets in the form of a sandwich. Initially, it is subtle, then thick, after - again thin. The task of thick gasket is to provide heat insulation. And so that the installation process is more convenient, the carburetor is installed on the collector without a lid. The damper drive must be in front of the car.
The throttle slicer is mounted - on the VAZ-2104 it will be more convenient if it turns out to be from the head of the GBC. Kulisu or "helicopter" sometimes drank in the center so that it goes to the carburetor smoothly. And so that the flap does not jin on the spring on the spring, plastic tips are installed on the thrust.

Next, stretch the suction drive cable over the cover of the GBC and customize it at the required length. Adjustment is carried out by changing the length of the casing. Then the cable is connected to the carburetor.
After that, you can install the upper lid.
Next, the fuel supply hose, "returns", heating, is connected to the carburetor. The "Furniture" hose is equipped with a check valve. Returning spring clings to the axis of the old scene on the cylinder head cover.

Now the solenoid valve should be connected to the lighting relay, to a positive contact.
Next, the air filter and its cover is mounted in its place.

All, on this work on installing the unit completed. But to operate it is too early. You need to properly configure the carburetor. Below we will tell you how to do it right.

With standard Zhymers "Solex" will not be able to hit the dynamics. In this case, you can replace the carburetor on 21073. Without changes, the installation is quite possible, but the poor mixture will be prepared in the first chamber. Therefore, at the first chamber, the motor will not be able to provide sufficient thrust for overclocking. The car will very slowly gain speed.

The movement rate will dramatically improve when the second camera opens. And the car will jump forward, like a goat. But the fuel efficiency is very low.

The problem can be solved by the selection of the main fuel gibber in the first chamber of the carburetor. If you replace it with 107.5 to 110, then you can get an improved overclocking intensity. This is a compromise between savings and dynamics. Optimally - 115th fuel jaw in the first chamber. Can be installed and 117.5. But the flow will increase even more. The mixture is converted to this jibrier, and the dynamics may worsen.

Air jets of the first chamber - 145, 150, 155. With fuel 117,5, you can install air 165.

Adjusting VAZ 21083.

Engine must be warm up, then set the level in the float chamber using special templates. The best level of fuel is approximately 23 mm from the bottom. As for the mixture, the best result is obtained if the screw is unscrewed by 2 turns, and the quality screw is 4-4.5 turns. However, when idling can be other installations.

Conclusion

All those who know how to customize "ozone" will be able to solve the question of how to adjust the carburetor "Solex". And how can the classic VAZ can be upgraded, we told in this article.

As a rule, the selection of fuses on the carburetor Colex 21073 produces during its adjustment on the engine. Some of the drivers sometimes think that if a dream came true, and the seks on the car, finally, is installed, then all the problems of the prosecution will be resolved. But it was not there! The main work is just starting after installation. Solex, designed to save you money on fuel resources so that it functioned correctly, you must also adjust exactly.

Well, if there is a familiar carburetor. And if not? You can try to adjust your own hands, but for this procedure you need to know at least more information about the carburetor itself.

Selection of types of juices on the carburetor Colex 21073 is one of the components of its adjustment for the most reasonable further operation. And before replacing one thing to another, it is necessary to understand the root: why, and what is this detail?

Theory

(Banner_Content) The engine through the diffuser sucks air, and through the fuel bustler - and a certain amount of gasoline. The volume of the engine depend on the volume of suused air and fuel. Therefore, the trend: to put a small jaw for a larger volume of the engine. And if you have to install a similar carburetor Solex 21073 on a small volume engine (for example, 1.5), then regular jetters are poor (that is, they give an unsaturated mixture).

Therefore, it can be said that everything starts with fuel gibber - its collections and settings. After, in the second head, you need to choose an air. Starting - strictly from the first chamber, until you set up, the second is not recommended in any way.

Rule: Gilkers We select by the volume of the engine. And best of all, before starting the setup, find the factory selection, which corresponds to the volume of the unit on your machine, and to rearrange from it (or put the same) jets.

Fundamentals of the selection

If we put, for example, Solex 21041 (volume 1.8) on the engine 1.5. This carburetor with diffuser 24x26, fuel - 102.5, and this is not enough for the engine 1.5. We are looking for coincidence of cameras and diffuser. We find the nearest of the options: Solex 21073. It with a 24x24 diffuser and 107.5 with DFFUZ. And the first cameras practically coincide. By the way, if the diffusers are almost the same, and the volume of the motor is smaller, then gasoline suction will be smaller (fat is poor). So, the TH (fuel jetters) is needed from 110. We recruit several.

Next you need to decideWhat you want to get: economical slowness or costly pickup. Depending on the solution, we select and TJ: to adjust the enrichment or depletion of the mixture of air and fuel (depleted will lead to gasoline savings, but will affect the overclocking dynamics of the car).

Several examples how to choose

Machine 1.8 liters. Carb - Solex 21073 (24x24). The first chamber is fuel - 115, air - 165. In the second: TZh - 115, air (VZh) - 125th. idle: 41st. With this situation, the flow rate of AI 92 for the urban travel mode - from 8 to 9 liters.

1.5 D. engine. Carb - Solex 21073. In the first - 115th, VZh - 155 ZD. In the second - tzh 115, VZH 135 ZC. XX - 41st. Gasoline AI 80. Consumption - Route 10, city 12.

Additional Information

In general, except for the selection of jecles, there are also a lot of useful and interesting nuances of setting up the salts, so that it worked correctly and combined with the engine of your carburetor car.

Starting always follows from setting levels in the chambers. Manually installed on the positions of the floats themselves, depending on the cover of the unit (everything is done on special templates). And in vain, you think, like many gullible users of Soleks, which is there from the factory, they say, everything is already exhibited. To not led to overflow and load on the needle - we produce the appropriate settings, flexing float tongues.

After installing the levels, you can go and idle. It depends on the position of the quality of the quality screws and the amount of the mixture (the twist is done with the remix removed).

RESULTS

Of course it is clear that there is no limit to improvements. Sometimes they can even go to excesses: drill, for example, the throttle valve, polish MD, secure epulsion tubes on the carburetor. But, as they say, beyond measure, then unhealthy. But such a procedure, in its fascinating, as the selection of the types of jets on the carburetor Colex 21073, for example, the thing is sufficiently necessary to correctly adjust the unit and its complete compatibility with a motor compartment. As a result, you get an economical and well-reacting car.
