Carburetor, carburetor diagnostics, carburetor cleaning with their own hands

Although many motorists believe that carburetor models of transport are a remnant of the past, and prefer injector engines, we must not forget about them. After all, today, on our roads there are not so few cars with carburetor variation of the fuel system. Therefore, the cleaning of the carburetor is still an urgent topic that we will discuss in this article.

Carburetor device

The main purpose of the carburetor in the vehicle is to prepare the fuel mixture - respectively, with the requirements of the modes of operation of the motor, the fuel saturation with air in the required quantity, followed by its feed to the motor cylinders.

The carburetor is one of the complex devices of power systems, the classic version of which, as a rule, consists of:

  1. Throttle and air dampers.
  2. Air and fuel canals with gibeles.
  3. Mixing chamber.
  4. Spray.
  5. Diffuser.
  6. Float with a locking needle valve.
  7. Float camera.

The desired amount of fuel in the float chamber is supported by the float, which is aligned with a needle valve. In the measure of how fuel is consumed, the float is descended, and thus opens a needle valve, after which the required portion of gasoline is in the fuel cell. When the required level of fuel is reached, the float chamber occurs a float, which covers gasoline access to the chamber using the needle through the inlet.

Gasoline from the float chamber through the spray tube enters the mixing chamber, where it is enriched with air through the inlet nozzle. The level of fuel in the float chamber is slightly smaller than the level of the outlet, with the result that, with a non-working motor, gasoline does not flow from the float chamber, even when your vehicle is under a slope.

The main purpose of the diffuser is to pump the speed of air-flow in the center of the mixing chamber. In addition, at the end of the sprayer creates a discharge in the operating mode of the motor. It is necessary for the outflow of fuel from the fuel chamber and its more efficient spraying.

The level of the fuel mixture, which is supplied to the motor cylinder, is regulated by a throttle valve, which is interconnected with the gas pedal. The flap changes the cross-sectional area after the mixing chamber. In the measure of an increase in the area of \u200b\u200bthe flap, fuel will be enriched, respectively, the modes of operation of the motor, which adjusts the driver's degree of pressing the gas pedal.

In addition, as a rule, under the dashboard, and, in some cases, there is a special lever that controls the damper of the carburetor (car enthusiasts referred to its "SUPPLCOM"). Having stretched it, the motorist covers the air-damper, thereby limiting air access and increasing the discharge in the mixing chamber.

As a result, gasoline from the float chamber is more efficiently suused, and the lack of air is prepared for the motor saturated combustible mixture, which is needed to start a cold motor.

Based on all the above, it can be said that the most economical carburetor works with optimal loads. And the movement of the jerks significantly increases the consumption of fuel, as during a sharp pressure on the gas, the motor is needed a more rich mixture.

The carburetor works badly, what it affects

Depends very much from the performance and status of the car carburetor. This applies not only to the stability of the engine, but also to its trading and ability to instill. In addition, a faulty carburetor contributes to the overexposure of fuel, which is quite unpleasant, given today's prices for it.

In turn, the operation of the carburetor depends on the mass of small elements with jewelry, which requires a careful and reverent attitude, so the maintenance of the carburetor and its repair should be carried out carefully and as much as possible, so that it would not hurt his work and not break anything.

Carburetor, how to check the tightness of the connections in the carburetor, how to eliminate looseness

Often the reason for the instability of the carburetor becomes air, which is formed in places where it should not be in any case. Usually, air sources are butt connections, places where the inlet pipeline is adjacent to the throttle housing, and the drying gasket.

It is quite difficult to see the locations of the air in the unarmed eye. Therefore, for their detection, it is often necessary to cover the "suspicious" places with soap foam and ensure that air bubbles arise. Detect disruption of tightness You can also protect the place of the joint of the dry cloth, after which it is necessary to wait a few minutes. In the presence of violations of integrity on dry places, a wet mark is formed. Diagnose disruption of the tightness of the intake nozzle can also be on the specific trails of Gary, which appears at the place of air entering the air.

When the point of tightness impairment is detected, try tightening the nuts, then repeat the check. The suspender should be done evenly so as not to cause a skew, which can only aggravate the problem. But even if the suspension helped, it is advisable to replace the gasket, as it is quite soon a problem can resume. Before installing the new carburetor gasket, rinse the joints of the jacks with gasoline.

Cleaning the carburetor, my mesh filter carburetor

To withdraw a mesh filter, you need to get the fuel filter tube. Next, flush the filter by gasoline. Then you need to blow it with compressed air, for which the usual pump is suitable with a conical nozzle or compressor. In addition, the fuel supply nozzle should be visually inspecting. If it is damaged, make it replacement.

Cleaning the carburetor, how to rinse and blow a needle valve cover of a float chamber

The most vulnerable place of the float chamber is a needle valve of the lid, as a result of the fact that he is strongly exposed to pollution. With normal operation, the valve goes freely, while the ball is located in the seating location and moves without jail. Like a mesh carburetor filter, the needle valve must be rinsed and blowing.

Cleaning the carburetor, in what state of the float

You should also pay attention to the float. Inside its cameras should not be fuel, there should be no cracks on the float itself, and he himself must move freely and do not hurt the walls of the carburetor. If you find a seating or disabilities, you need to eliminate friction and close the hole or replace the float to the new one. In addition, you need to follow the centers and regulate it, if necessary, gradually flexing the tongue to the desired degree.

Carburetor jackets, cleaning and checking jets and canals

To clean the channels and jags, it is necessary to use a solvent, gasoline and a clean rag without a pile. Most often pollution resemble a resinous flaw. In some cases, it is necessary to use something more solid for cleaning than the rag, for example, sharpened racks from the tree.

What is brushing, which rag can be used and why metal items can not be used for cleaning

In no case cannot use metal items to clean the carburetor, as they can damage smooth surfaces, after which the carburetor may well stop working. In addition, scratches contribute to repeated and fairly fast pollution. The cleaning vehicle must necessarily be without a pile, as it can again disrupt the carburetor.

Cleaning the carburetor, how to wash the accelerator pump

The flushing of this element should be made by the same principle as the flushing of the other parts of the carburetor. Pay attention to the movement of the ball in the nest of the sprayer, which should be free. In addition, check the course of the lever, its movements must be smooth without hooks, in principle, as well as all other elements of the carburetor. We check the integrity of the surfaces of the gaskets and the tightness of the seals, the adjuncture should be dense without cracks. In the presence of faults, you should replace the broken parts.

Cleaning the carburetor, in what state should there be a diaphragm of an economizer

The economizer's diaphragm must be a whole, without visible damage, the pusher must have a standard length, if it is less permissible, the diaphragm with the pusher needs to be replaced.

Tips of professionals

It is worth noting that when buying a cleaner for the carburetor, it is necessary to stop your choice on the means that are intended for this, since there is a risk of damaging the elements of the carburetor and it will stop working. Do not forget to carefully examine the instructions before applying the cleaner. In addition, in a timely manner, carry out the necessary maintenance of the carburetor, in particular, its cleaning, replacement of damaged and worn elements, as well as adjusting the idle.
