4.1.2. Compression check
THE GENERAL DATA

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 deterioration of the engine, without waiting the moment when deterioration will be shown in a low overall performance of the engine.

PERFORMANCE ORDER
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 aperture 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 проворачивания a cranked shaft pressure of compression should increase by one or two turns to a maximum, and then be stabilised. Make record of the maximum received result.
4. Similarly check up a compression in other cylinders. The compression in all cylinders should not differ more than on 1,0 bar. Pay attention that the compression size should increase quickly on the serviceable engine. The low compression on the first turn of the cranked shaft, accompanied by gradual increase in pressure at the subsequent turns of a cranked shaft, specifies in deterioration of piston rings.
5. The low compression on the first turn of a cranked shaft which slightly increases further, specifies in a thinness прилегания the valves, the punched lining of a head of the block of cylinders or crack presence in a head of the block of cylinders. Deterioration of the ends of cores of valves can lead to a low compression also.
6. If a compression in one cylinder lowered conduct following test. Fill in through a candle aperture in the cylinder of a few engine oil and check up a compression.
7. If oil pouring 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 specifies in a lining burn-out between cylinders.
9. If the compression in one cylinder is less on 20 %, than in the others, and the engine works unstably idling, it specifies in the worn out cam of a camshaft.
10. If pressure of compression is too high, it specifies that the combustion chamber is covered by a thick layer of a deposit.
11. After this check screw in spark plugs and connect a wire to the ignition coil.
