System of a perepuskaniye of soaked-up air – the general information, check of a condition and replacement of a diaphragm of the IAB valve

General information

Some models are equipped with the IAB system providing possibility of a perepuskaniye of air soaked up in the engine in the chamber of combustion. The inlet pipeline on such models is equipped with two air channels that allows to optimize supply of air the engine depending on specific conditions of its functioning. Maximum efficiency of return is reached at the expense of operation of valves switches depending on the current turns of the engine. The closed position of valves allows to achieve the maximum torque at low turns of the engine, open serves for receiving the maximum capacity at high turns.

Check

 PERFORMANCE ORDER

1. At the muffled engine disconnect a vacuum hose from a diaphragm of IAB and connect to the last manual vacuum pump (see an accompanying illustration). If the rod of a diaphragm remains motionless, replace assembly.

2. At the engine working at single turns make sure available depression on the open end of the disconnected vacuum hose. Depression should take place idling, disappearing at increase of frequency of rotation of the engine to 6000 rpm.
3. If on single turns depression is absent, walk on a vacuum hose from a diaphragm to the valve of management located under the inlet pipeline and further – to the vacuum tank. Disconnect a hose going from the tank to the inlet pipeline and check it on depression existence. If depression is absent, check a hose existence of cracks and blocking signs.

4. Disunite the socket of the electromagnetic IAB valve (see an accompanying illustration). Connect positive щуп the voltmeter to the plug of a red-dark blue wire in the socket from a plait, negative – to the plug of a black wire. At the included ignition tension of the battery should take place. If tension is absent, check a condition of electroconducting and quality of its contact connections.

5. If tension takes place, and vacuum lines as it should be, replace the electromagnetic valve.

Replacement

 PERFORMANCE ORDER

1. For replacement of a diaphragm turn out screws of its fastening (see an accompanying illustration).

2. For replacement of assembly of the electromagnetic valve with the vacuum tank weaken a fixing collar (see an accompanying illustration).

3. Installation is made upside-down.
