2.1.13. Diagnostics of malfunctions of the engine

GENERAL INFORMATION

If the engine does not work, it is necessary to eliminate malfunctions systematically. In order that the petrol engine could work, performance of two conditions is necessary: the toplivovozdushny mix should move in cylinders of the engine and between electrodes of spark plugs the spark should slip. First of all it is necessary to check spark existence on spark plugs.

PERFORMANCE ORDER

1. Unscrew a spark plug and fix it the block of cylinders of the engine.

2. Connect to a spark plug a high-voltage wire. Hold a spark plug special nippers with the isolated handles.

3. Turning the engine a starter, check spark existence between spark plug electrodes.

Prevention

At spark stock-taking between spark plug electrodes in the engine gasoline as the catalyst in this case will fail should not arrive. For this purpose disconnect electric sockets from fuel nozzles. If the spark slips between spark plug electrodes, means, ignition system as it should be.

REASON	ELIMINATION METHOD
The complicated start of the engine or the engine is not started
The wrong actions at start of the petrol engine	Tighten the hand brake and press coupling. On models with an automatic transmission establish the selector lever in the situation "R" or "N". Turn of the ignition key start the engine and after start of the engine release the ignition key. Do not press an accelerator pedal. Movement can be begun at once after engine start, even in the winter. If after an engine provorachivaniye during 10 seconds the engine was not started by a starter, interrupt process of start of the engine and repeat it at least in 30 seconds. In several consecutive attempts of start of the engine the catalyst as not burned down fuel gets to an exhaust system can be damaged and precipitates on catalyst cells. At start of the hot engine after the engine will start to work, slightly press an accelerator pedal
Low compression in engine cylinders	Replace laying of a head of the block of cylinders or make major maintenance of the engine
Faulty safety lock for: – electric fuel pump, – electronic system of injection	Check fuses
Malfunction of fuel system	System pollution, the pipeline is bent or deformed. Check amount of submitted fuel
The starter turns the engine very slowly	Charge the accumulator. Check an electric chain of a starter
Wrong phases of a gazoraspredeleniye	Check gazoraspredeleniye phases. Check a tension of a gear belt
