10.15. Adjustment of turns of idling and the contents WITH in exhaust gases

GENERAL INFORMATION

Adjustment of turns of idling of the engine is carried out with application of an exact tachometer without removal of the air filter.

Access to the screw of adjustment of turns of idling
Access to the screw of adjustment of turns of idling is possible through dredging in the lower part of a casing of the air filter.

Use of a face key for adjustment of quality of a fuel mix

PERFORMANCE ORDER
1. Establish the analyzer of exhaust gases in an exhaust pipe.
2. Start the engine in an idling mode. On cars with an automatic transmission establish the selector lever in the situation PARK. Check that all electric consumers, including the conditioner, are switched off.
3. The screw of adjustment of turns of idling is available through dredging in the lower part of a casing of the air filter (see fig. Access to the screw of adjustment of turns of idling).
4. Rotating the adjusting screw, establish demanded turns of idling. Quickly increase engine turns, then repeatedly measure and, if necessary, adjust idling turns.
5. For contents adjustment WITH in exhaust gases remove a casing of the air filter, take a cap of the screw of adjustment of quality of a mix and repeatedly establish a casing of the air filter.
6. Start the engine in an idling mode, then for 10 seconds increase engine turns to 2 000 rpm and repeatedly return it to an idling mode.
7. Check the contents WITH. For contents adjustment WITH establish a face key in a tube of the screw of quality of a mix and press a key in order that the regulator entered into gearing with the adjusting screw (see fig. Use of a face key for adjustment of quality of a fuel mix).
8. Rotating the adjusting screw, adjust the contents WITH. Screw rotation clockwise enriches a fuel mix, and counter-clockwise impoverishes.
9. Quickly increase engine turns to 2 000 rpm, then transfer the engine to a mode of idling and repeatedly measure the contents WITH. At carrying out adjustment turn the adjusting screw of quality of a mix each time only on a turn half.
10. Remove from the car all instrumentations and establish a new cap on the screw of adjustment of quality of a mix.
