5.2.9. Start of the cold engine

GENERAL INFORMATION

On engines 1,7 the thermostatic capsule which operates the cold engine and reduces emissions of harmful substances in exhaust gases is installed in the fuel pump. The thermostatic capsule contains an element which extends depending on temperature of cooling liquid and changes the fuel injection moment, increasing turns of the cold engine by 150 rpm.

On engines of 2,0 l turns of idling and the moment of injection of fuel are defined by the ECU block.

Adjustment

PERFORMANCE ORDER
1. Warm up the engine up to the working temperature, check turns of idling and cool the engine.
2. On the cold engine check a gap between the screw of adjustment and a control lever of the fuel pump. At a temperature of cooling liquid of 20 °C the gap has to be ranging from 0,8 to 1,1 mm.
3. For adjustment of a gap weaken a lock-nut and, rotating the adjusting screw, establish the required gap then establish a lock-nut.
4. Start the engine and check idling turns. If turns of idling differ from demanded, weaken a lock-nut and, rotating the adjusting screw, establish the required turns then tighten a lock-nut.
5. Warm up the engine and check idling turns. In the course of warming up of the engine the gap between the adjusting screw and a control lever of the fuel pump has to decrease gradually before full contact of the screw with the lever. Otherwise there is a damage to system of cold start of the engine, and it is necessary to make repair at a maintenance stage.
