6.4.1.1.3. System рециркуляции


The system structure includes the valve рециркуляции, the return valve and the thermovacuum distributive valve (ТВР).

Check on carburettor engines

PERFORMANCE ORDER
1. For check disconnect hoses from these valves and blow, air should pass freely through hoses.
2. Check ТВР is described in subsection 6.4.1.1.2.
3. For valve check рециркуляции disconnect a vacuum hose in the top part. Attach an auxiliary hose and create in it depression. Check up a diaphragm course, having put a finger to the bottom part of the valve. If the diaphragm is motionless, the valve replace.
4. If ТВР it is serviceable, check up the return valve. For this purpose warm up the engine and disconnect a vacuum hose from the valve рециркуляции. Put a finger to a hose, sharply increase and dump engine turns. At increase of turns in a hose depression which should weaken slightly at сбрасывании turns should be felt. Otherwise the return valve replace.

Check on инжекторном the engine

The check technique same, as on the carburettor engine behind that exception that instead of ТВР is checked the solenoidal valve.

The solenoidal valve differs nothing from the valve of system of catching of steams of gasoline and is checked similarly (subsection 6.4.1.1.2 see).

VALVE RETSIRKULJATSII

Replacement

PERFORMANCE ORDER
1. The valve рециркуляции on инжекторном the engine (it is specified by an arrow) is mounted in the left part of a soaking up collector. For access to the valve it is recommended to remove the air filter and the return valve. Disconnect from the valve a vacuum hose.
2. Release nuts of unions and disconnect tubes рециркуляции and the return valve.
3. Turn away 2 nuts, remove the valve and a lining.

THE RETURN VALVE

Replacement

PERFORMANCE ORDER
1. The valve is mounted in the left part of a soaking up collector (1 – screws, 2 – vacuum hoses). For access to the valve it is recommended to remove the air filter.
2. Disconnect from the valve vacuum hoses.
3. Оверните 2 screws also remove the valve.
4. The valve is established upside-down.

ТВР ON THE CARBURETTOR ENGINE

Replacement

Subsection 6.4.1.1.2 see.

THE SOLENOIDAL VALVE ON ИНЖЕКТОРНОМ THE ENGINE

Replacement

See subsection 6.4.1.1.2.

THE GAUGE OF THE CONTROL OF THE FULFILLED GASES


Check on carburettor engines

PERFORMANCE ORDER
1. Adjust quality of a mix of idling.
2. Open a diagnostic socket which is under колодкой safety locks.
3. Connect to conclusions of a socket the voltmeter.
4. Start the engine, finish turns to 2000 rpm and during 2 mines observe of the voltmeter. At the serviceable gauge of the indication of the voltmeter should пятикратно change from 0 to 12 In for each 10 seconds Otherwise the gauge more exact check in car-care centre service is faulty and necessary.

Check on инжекторном the engine

If the maintenance WITH in exhaust gases exceeds norm it is necessary to check up serviceability of the gauge of exhaust gases, using function of self-diagnostics of the processor block.

NEUTRALIZER

Replacement

Subsection 6.1.14 and subsection 6.2.16 see.

THE GAUGE OF EXHAUST GASES

Replacement

PERFORMANCE ORDER

The prevention

After falling or strong concussion the gauge can fail.


1. Disconnect a socket from the gauge of exhaust gases.
2. Get wires from скоб.
2. Turn out the gauge and remove together with a lining.
3. Establish the gauge upside-down. Grease a carving of the gauge with refractory greasing.
