What is an idle valve

An important detail of the modern engineis the idling valve. Unknowingly, many motorists often call it an idle sensor. In domestic cars VAZ this device is called the idle speed regulator, in GAZ - by the regulator of additional air, and in carburetor engines - by electropneumatic valve.

The idling valve performs the following function: supplies additional air to the intake manifold bypassing the throttle valve, thereby contributing to keeping the engine idling within the manufacturer's specified design. Idling valves can be different in design and performance, depending on the type of engine and brand of the car, but the function they perform is unchanged. So, for example, the solenoid valve of idling, relying on a lot of readings of sensors, is brought into operation by means of an electronic control unit.

The car owner should know that for optimalwork must be observed not only the interior of the car and the body, but also periodically clean and wash certain mechanisms. For example, to implement a stable idling, as well as easy and, not least, smooth car winding even in winter frosts, it is necessary to periodically flush the idling valve.

A pleasant effect of the procedure will beimmediately. Naturally, it is better to carry out this work with specialists. But if you perfectly studied the structure of your car, and know where the idle valve is located, you know firsthand, you can make this procedure yourself, thereby saving money. Moreover, for this work you only need a set of screwdrivers, sealant, WD-40 and free time.

After you unmistakably determinedlocation of the idle valve, disconnect the duct and other connectors from it. Then unscrew the fastening bolts. Between the intake manifold and the valve is a gasket, put it in a safe place, so as not to lose, like the bolts.

Next, proceed to disassemble the idling valve.

But you need to do this very carefully, because inIn addition to the idle valve itself, there can be "auxiliary" valves, which are often small in size, as well as spring-loaded, and looking for a lost small spring somewhere is not a pleasant occupation. In general, there are a lot of small parts in the whole design, these are small copper washers, and a rubber seal, etc. Therefore, the entire procedure should be performed very carefully to avoid undesirable loss of important and necessary trifles.

After parsing "for spare parts" everything is necessaryRinse thoroughly with "VD" or any other liquid with similar properties. You can proceed with the assembly of the mechanism. Motorists advise the place of the joint of the valve and the metal gasket (body) to be smeared on both sides with a sealant. Only without fanaticism, because the gaps are very small. Then screw the idle valve into place, attach all the connectors, if necessary, do not forget to make the idling adjustment.
