2.2.2. Compression check

If the engine works badly or with interruptions, check system of ignition and fuel system.

If it was not possible to find the reason of bad operation of the engine, inspect a compression. Regular carrying out this check will allow you to prevent emergence of malfunctions in advance also.

PERFORMANCE ORDER
1. Check level of engine oil. Be convinced that the starter works normally, and the storage battery is completely charged.
2. Start the engine and warm up it to temperature 80–95°C.
3. Switch off the engine and remove from spark plugs tips of high-voltage wires.
4. Turn out spark plugs.
5. Turn a cranked shaft of the engine.
6. Screw a tip компрессометра in a spark plug opening.
7. Completely open a butterfly valve.
8. A starter turn a cranked shaft of the engine approximately on 4 turnovers and of a scale of the device define a compression.

Compression: 1,47 MPas
Minimum admissible compression: 1,37 MPas

9. Repeat steps 6–8 on other cylinders.
10. If a compression low in all cylinders, through openings for spark plugs fill in in cylinders on нескольку a thaw of engine oil and repeat steps 6–8.

1) If filling of oil lifts a compression, probably, piston rings are worn-out.
2) If the compression remains at the same level, probably, valves burned through or laying of a head of cylinders is damaged.
3) Screw spark plugs and connect to them high-voltage wires.
