6.4.1.1.4. System доокисления exhaust gases

The system доокисления exhaust gases provides maintenance decrease in emissions of hydrocarbons and WITH at the expense of injection of filtered air in a final collector. Before hit of gases in neutralizer there is their additional oxidation. The system structure includes the solenoidal valve.

For serviceability check the solenoidal valve is recommended to be removed (see more low).

Check

PERFORMANCE ORDER
1. At food giving (12В) air should pass freely through the union And and Century
2. If result of check negative it is necessary to replace the valve.
3. Remove the valve эжекции air (see more low).
4. At a purge through the union In air should not to pass. If on the union And to create depression air should pass from In in With, in the opposite direction (from With in) air should not to pass under no circumstances (And – a vacuum hose from the solenoidal valve, In – a hose from the air filter, With – to a final collector).
5. If result of check negative it is necessary to replace the valve.

THE SOLENOIDAL VALVE

Replacement

PERFORMANCE ORDER
1. The solenoidal valve will screw in the left part of a soaking up collector.
2. Disconnect the battery from weight, disconnect a socket.
3. Designate an order of joining of all hoses.
4. Ослабьте collars also disconnect hoses.
5. Remove the valve from an arm.
6. Installation is carried out upside-down.

AIR VALVE EZHEKTSII

Replacement

PERFORMANCE ORDER
1. The valve эжекции air is mounted on the left cap of a suspension bracket.
2. For valve replacement disconnect hoses (are specified by arrows).
3. Turn away bolts and remove the valve.
4. Installation is carried out upside-down.

THE PROOF-READER OF IDLING

Check

PERFORMANCE ORDER
1. Uncover the air filter. The valve () idling corrections (it is specified by an arrow) is mounted in the bottom of the case of the filter.
2. Prepare the thermometer and the hair dryer. Heat up the valve the hair dryer. The valve should be closed at temperature more low 55 With, be slightly opened in a range 55–65 With and completely open at temperature above 65 S.Esli 2 valves temperature characteristics of one valve precisely same, and the second the valve is closed at temperature more low 65 With are provided, slightly opened in a range 65–75 With and completely opens at temperature above 75 With At full cooling the valve should be closed completely.
3. At negative results of check the valve replace.

Replacement of the valve of correction

PERFORMANCE ORDER
1. Remove the air filter.
2. Disconnect a hose, turn away screws and remove the valve.
3. The valve is established upside-down.

THE PNEUMOSHOCK-ABSORBER


Check

At вталкивании a pneumoshock-absorber rod resistance should be felt, and at отпускании the rod should come back quickly in a starting position.

Otherwise the pneumoshock-absorber replace.

Replacement

PERFORMANCE ORDER
1. On carburettor engines turn away 2 screws and remove the valve from the carburettor.
2. On инжекторных engines Turn away a nut and get the valve from an arm of the case throttle заслонки.
3. Establish the pneumoshock-absorber upside-down and check up adjustment. On the heated-up engine the pneumoshock-absorber rod should adjoin to the adjusting screw at 1900200 rpm. For adjustment turn away a counternut and expose the screw in the necessary position at the specified turns, again check up adjustment.
