4.1.2. Compression check


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

1. Warm up the engine to working temperature. Thus the accumulator should be completely charged. Unscrew spark plugs.
2. Disconnect ignition system for what disconnect from a cover of the distributor of ignition the central high-voltage wire and earth it.
3. In an opening of a candle of the first cylinder establish компрессометр. The assistant should press an accelerator pedal against the stop and turn the engine a starter. After a provorachivaniye of a cranked shaft or two turns pressure of compression should increase by one to a maximum, and then be stabilized. Make record of the maximum received result.
4. Similarly check a compression in other cylinders. The compression in all cylinders should not differ more than on 1,0 bar. Pay attention that the size of a compression should increase quickly on the serviceable engine. The low compression on the first turn of the cranked shaft, accompanied by gradual increase in pressure on the subsequent turns of a cranked shaft, indicates wear of piston rings.
5. The low compression on the first turn of a cranked shaft which slightly increases further, indicates a thinness of a prileganiye of the valves, the punched laying of a head of the block of cylinders or crack existence in a head of the block of cylinders. Wear of the ends of cores of valves can lead to a low compression also.
6. If a compression in one cylinder lowered, carry out the following test. Fill in through a candle opening in the cylinder of a little engine oil and check a compression.
7. If oil filling in the cylinder increases a compression, it specifies that the cylinder or piston rings is worn-out.
8. The low compression in two next cylinders indicates a laying burn-out between cylinders.
9. If the compression in one cylinder is less for 20 %, than in the others, and the engine works unstably idling, it indicates a worn-out cam of a camshaft.
10. If pressure of compression is too high, it specifies that the chamber of combustion is covered with a thick layer of a deposit.
11. After this check screw in spark plugs and connect a wire to the ignition coil.
