Compression check

All engines

Check of a compression allows to draw a conclusion on an engine condition. Namely, at check it is possible to define, whether as it should be valves and pistons (piston rings), or they are worn-out. Besides, results of check specify that the engine needs repair. For check it is necessary компрессометр which for petrol engines can be got cheaply in a firm network.

The pressure difference between separate cylinders can make 2,0 Bar as much as possible. If in one or several cylinders pressure differs more than on 2,0 Bar, it is a sign of faulty valves, worn-out piston rings or a mirror of cylinders. If the limit of wear is reached, the engine should be repaired or replaced.

    For compression check the temperature of the engine should make a minimum +30°C. Then the oil filter has hand temperature. The temperature of the engine should not be too big, differently at a vyvinchivaniye of spark plugs the carving in a head of cylinders can be damaged. To switch off ignition.
    Petrol engine: To disconnect the tip from the plug 15 on the ignition distributor.
    Diesel engine: To disconnect the tip from the valve of interruption of supply of fuel.

If not to disconnect the tip, at a provorachivaniye of the crankshaft fuel will follow.

    Petrol engine: To disconnect all tips of spark plugs. For this purpose there are special nippers, for example, HAZET 1849. To blow niches of candles in a head of cylinders the compressed air and to unscrew spark plugs a candle key. Diesel engine: To remove nozzles and to block returnable топливопровод on TNVD (the fuel pump of a high pressure), see. Head Diesel engine. Several times to turn the crankshaft a starter, to remove the soot remains.

To establish a transmission in neutral situation, to tighten the hand brake.

    To insert or screw in компрессометр in a candle opening according to the instruction. To ask the assistant to squeeze out completely a pedal of gas and to hold during all check. Let's to the crankshaft be turned on 8 turns while the device will not cease to show pressure increase. To check all cylinders and to compare to demanded value. Petrol engine: To screw in spark plugs and to connect cables, see. Head Introduction. Diesel engine: To establish nozzles, see. Head Diesel engine. Petrol engine: To connect the tip to the plug 15. Diesel engine: To connect the tip to the valve of interruption of supply of fuel.
