3.3.3. Check of pressure of compression

GENERAL INFORMATION

Check of a condition of the engine can be made by measurement of pressure of compression in cylinders. If to make this check regularly, then it is possible to learn the beginning of wear of the engine in advance, without waiting for the moment when wear is shown in low overall performance of the engine.

Using компрессометр with an adapter, check compression pressure in engine cylinders.

Before check of pressure of compression check that the accumulator was charged also in good shape. The air filter has to be pure, and the engine has to be heated-up up to the normal working temperature. Before check unscrew glow plugs. For prevention of start of the engine when conducting check disconnect the electric socket from the control unit of the fuel pump of high pressure.

Establish an adapter with kompressometry in an opening for installation of candles of an incandescence.

Turn the engine a starter. After a provorachivaniye of a bent shaft by 1 or 2 turns pressure of compression has to increase to a maximum and then be stabilized. Make record of most received result. Similarly check other cylinders.

Compression pressure in all cylinders should not differ more than on two units. Pay attention that the size of compression has to increase quickly on the serviceable engine. The low pressure of compression on the first turn of a bent shaft accompanied with gradual increase in pressure on the subsequent turns indicates wear of piston rings. The low size of pressure on the first turn of a bent shaft which slightly increases further indicates a thinness of a prileganiye of valves, the punched laying of a head of the block of cylinders or existence of cracks in a head of the block of cylinders.

After conducting check of pressure of compression connect the electric socket to the control unit of the fuel pump and establish glow plugs.
