Adjusting the carburetor VAZ 2107, as, indeed, all other similar models, is one of the current topics, not only in the Internet network, but also in everyday life.
Adjustment of the carburetor WHA strongly affects thefuel consumption, as well as on the uniformity of the engine, its acceleration. It directly affects premature wear of certain parts. The ignition of the carburetor VAZ, the fuel level in the float chamber, the calibration of the jets or their throughput, and the condition and operation of some basic mechanisms are checked and, if necessary, adjusted. In addition, in some cases in the carburettors an additional position is set for the adjusting needle in the main jet. Adjustment of carburetor VAZ 2107 should be carried out at least once a year. It is desirable that this work produced by a specialist in the workshop. This is because the adjustment of the carburetor VAZ 2107 or other models of this car manufacturer is similar to setting the piano for good sound. At the same time, if this musical "gentle" instrument is bad to play, then nothing terrible will happen.
These components of the car with the injection systemare intended for mixing of air with automobile fuel. As a result, a fuel-air mixture is formed in certain proportions. As a rule, if the adjustment of the carburetor VAZ 2107, 2108, etc. is carried out correctly, then for each gram of gasoline should account for about fifteen grams of air. Such a composition is called stoichiometric. In our country, the most popular carburetors are the series "Ozone", "Solex" or "DAAZ". They are used on the domestic "seven" and "eight". Due to the wide distribution of carburetors VAZ 2108 and VAZ 2107 they can be repaired even in the garage, without resorting to help in branded services. Some motorists carry out not only adjustment of the carburetor VAZ 21083, but also its repair. This became possible due to the large amount of necessary information on the Internet, in books and car magazines, and also because of the fairly simple design of the device.
Adjustment of carburetor VAZ 2103 and latermarks begins with the procedures included in the list of its maintenance. Firstly, it is washing or cleaning, which is a prerequisite for the simple reason that it is much more pleasant to work with a clean appliance. In addition, cleaning the carburetor elements is very positive for its performance. At the same time, a strainer with a float chamber and jets is washed with both air and fuel.
Adjustment of the float mechanism is not verycomplex, but fairly responsible stage. It is divided into three stages. Correct adjustment of the carburetor VAZ 21099 and other models is an adjustment of the amount of fuel in its float chamber. For this, a special cardboard pattern is prepared, six and a half by fourteen millimeters in size.
Adjustment of carburetor VAZ 21099 at this stageis to quickly and qualitatively correct the function of the mechanism of the launch unit. To begin with, experienced motorists prepare a short piece of wire with a diameter of 0.7 or 0.8 millimeters, as well as a template made of fairly dense material, with a width of up to five and a half millimeters. Then the air filter of this car is removed, and then the carburetor is completely cleaned, for which its damper is completely closed. In this case, the tail of the thrust, connecting the stem on the starting device with the lever on the air damper, must necessarily have a position such that, without moving anything, one could take a position at the very end of the groove. Adjustment of the carburetor VAZ 2105 requires mandatory verification of the open throttle. For this purpose the device is removed from the machine. Then, on the carburetor located outside the car, counterclockwise until the stop, the three-arm lever turns. Then, using a pre-prepared wire, a gap is checked, which in normal condition should correspond to a maximum of 0.8 millimeters. Otherwise, you need to bend the rod or rotate its tip into another hole.
The carrying capacity of these chassis partscar directly affects the composition of combustible mixtures. In this case, the deviation from the manufacturer's specified value or parameters, calibers, diameters for jets to the side greater or smaller, not only makes the engine less efficient, but also leads to an increase in the fuel consumed. With a reduction in the cross-sectional area of the jet or the depletion of the mixture, this may lead to a sharp deterioration in the driving qualities and the acceleration of the car. The throughput of these parts is measured by the volume of water flowing through them during one minute at twenty-degree temperature and under a meter head of water column. It changes with time. Slightly increases the cross-sectional area of the jet, especially with frequent use of low-quality gasoline. In addition, while the engine is running with a large flow of gases through the piston rings, this parameter is somewhat reduced due to the formation of resin plaque in the calibrated holes.
Adjustment of the carburetor assumes severaladjustments. In particular, this applies to the operation of the drive on the air damper. The order of the work is as follows: first you need to remove the air filter of the car. Then, holding the handle of the same flap, start gently moving it in the direction opposite to itself. Do this until the vertical position is reached. The air damper itself must also be in the same position. If this is not achieved, then you need to adjust.
While holding the bushing from turning, and for this purpose,hand must have a seven-millimeter key, the screw, through which the traction was secured at the air damper, is weakened. After the unscrewed part must be tightened in the opposite direction. In the fully retracted position of the handle, the inlet on the throat should be closed by an air damper. That's all. And then in the reverse order is installed in place and the air filter is removed.
Experienced motorists, who are not the first yearat the wheel "zhigulyat, know that the carburetor VAZ 21213, the adjustment of which does not cause difficulties, it is better to buy from the manufacturer DAAZ. It is best for the VAZ of this model suited devices from the "Solex" series. Their feature is that the design of these carburetors is suitable not only for front-wheel drive vehicles, but also for almost all brands. In addition, their necessary parameters in the preparation of the fuel-air mixture are achieved by using special sets of jets and diffusers of certain sizes, chosen depending on the volume of gasoline engines of the car. Unlike the Ozon carburettors in Solexa, the connection between the throttle valves in the first two chambers is mechanical, not gas-dynamic. Another feature of the latter is that they have a conventional system when idling. Therefore, when adjusting the carburetor of this brand, the screw for the amount of the mixture actually opens the throttle valve in the first chamber.
During operation, the carburettor is not necessaryregular external washing. Such a need arises only when the moving mechanisms are heavily soiled, as a result of which the mobility of the parts is impaired. In addition, "bathing" is necessary before adjustment. Of course, there is a periodicity for the implementation of preventive auto events. And if, for example, on the "Lada" of the seventh model carburetor repairs can be made only when the old unit fails, then, without waiting for a serious breakdown, the valves must be adjusted. VAZ 2107, the carburetor of which must be checked for clearances every maximum of fifteen thousand kilometers, otherwise it can stand in the middle of the road, and then without the aid of the evacuator of the "iron horse" you can not drive home. That's why it will be much easier to spend a few hours to independently check it or take the car to a service point.
For internal cleaning of the carburetor with itsadjustment of the use of brushes and rags is not recommended, since fibers or bristles can accidentally enter the jets. To care for this component of the running gear of the car manufacturers produce special preparations. Some experienced drivers use for this purpose gasoline or kerosene, as well as a solvent, sometimes compressed air. Only having cleared the carburettor, it is possible to start already to its adjustment. Be sure before taking such a serious interference in the course of his work, you must first of all make sure that all faults are associated with this particular unit, and not, for example, with an ignition or fuel supply system in which the fine filter of the pump can clog etc. And the main thing: in spite of the expansive-assertive capture of the automobile market by the injector engines, who know a lot about cars and have a long experience, drivers still prefer to have a carburetor on board their "iron" friend. After all, it is a pledge that the car will start even in a frigid frost. And in order for such a necessary device to work properly, you need to regularly monitor its condition: clean and, if necessary, adjust.
