Compression check

If the engine works badly or with faults, check up system of ignition and fuel system. If it was not possible to find the reason of bad work of the engine, inspect a compression.

Regular carrying out of this check will allow you to warn occurrence of malfunctions in advance also.


    Check up engine oil level. Be convinced that the starter works normally, and the storage battery is completely charged. Start the engine and warm up it to temperature 80–95C. Switch off the engine and remove filtering element of the air filter. Remove fuel atomizers. Turn a cranked shaft of the engine. Screw a tip компрессометра 09351 – 27000 in an aperture for a fuel atomizer. Starter turn a cranked shaft of the engine and on a device scale define a compression. A compression: 2942 kpa. Repeat steps 6–7 on other cylinders, having convinced that difference of pressure for each of cylinders is in admissible limits. Admissible difference of pressure in engine cylinders: 100 kpa.
      If a compression low in all cylinders, through apertures for spark plugs fill in in cylinders on нескольку a thaw of engine oil and repeat steps 6–8.
      If oil pouring lifts a compression, probably, piston rings are worn out; If the compression remains at the same level, probably, valves have burnt through or the lining of a head of cylinders is damaged.
