6.4.1.1.4. System of a dookisleniye of exhaust gases
The system of a dookisleniye of exhaust gases provides decrease in contents in emissions of hydrocarbons and WITH due to injection of the filtered air in a final collector. Before hit of gases in converter there is their additional oxidation. The solenoidal valve is a part of system.
For serviceability check the solenoidal valve is recommended to be removed (see below).
Check
| PERFORMANCE ORDER |
|
1. When giving food (12B) air has to pass freely through the union A and B. |
| 2. If result of check negative, then the valve it is necessary to replace. |
| 3. Remove the valve of ejection of air (see below).
|
|
4. At a purge In air should not pass through the union. If on the union A to create depression, then air has to pass from In in With, in the opposite direction (from With in In) air should not 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, then the valve it is necessary to replace. |
|
SOLENOIDAL VALVE
Replacement
| PERFORMANCE ORDER |
| 1. The solenoidal valve is screwed in the left part of the soaking-up collector. |
| 2. Disconnect the battery from weight, disconnect the socket. |
| 3. Designate an order of accession of all hoses. |
| 4. Weaken collars and disconnect hoses. |
| 5. Remove the valve from an arm. |
| 6. Installation is carried out upside-down. |
|
AIR EJECTION VALVE
Replacement
| PERFORMANCE ORDER |
| 1. The valve of ejection of air is mounted on the left cap of a suspension bracket. |
|
2. For replacement of the valve disconnect hoses (are specified by shooters). |
| 3. Turn off bolts and remove the valve. |
| 4. Installation is carried out upside-down. |
|
PROOFREADER OF IDLING
Check
| PERFORMANCE ORDER |
|
1. Uncover the air filter. The idling correction valve(s) (it is specified by an arrow) is mounted in the filter case bottom. |
| 2. Prepare the thermometer and the hair dryer. Heat the valve the hair dryer. The valve has to be closed at a temperature below 55 °C, be slightly opened in the range of 55-65 °C and open completely at a temperature above 65 °C. If 2 valves, then temperature characteristics of one valve just the same are provided, and the second the valve is closed at a temperature below 65 °C, is slightly opened in the range of 65-75 °C and completely opens at a temperature above 75 °C At full cooling the valve has to be closed completely. |
| 3. At negative results of check replace the valve. |
|
Replacement of the valve of correction
| PERFORMANCE ORDER |
| 1. Remove the air filter. |
| 2. Disconnect a hose, unscrew screws and remove the valve. |
| 3. The valve is installed upside-down. |
|
PNEUMOSHOCK-ABSORBER
Check
At pushing-in of a rod of the pneumoshock-absorber resistance has to be felt, and at an otpuskaniye the rod has to come back to a starting position quickly.
Otherwise replace the pneumoshock-absorber.
Replacement
| PERFORMANCE ORDER |
| 1. On carburetor engines unscrew 2 screws and remove the valve from the carburetor. |
| 2. On injector engines Turn off a nut and get the valve from an arm of the case of a butterfly valve. |
| 3. Install the pneumoshock-absorber upside-down and check adjustment. On the heated-up engine the rod of the pneumoshock-absorber has to adjoin to the adjusting screw at 1900±200 rpm. For adjustment turn off a lock-nut and expose the screw in the necessary situation at the specified turns, again check adjustment. |
