3.1.1.2. A compression

PERFORMANCE ORDER
1. At obvious deterioration of work of the engine, or in case of faults in work of cylinders at obviously serviceable to fuel system and ignition system, it is necessary to check up a compression in cylinders. Results of check of a compression give most a trustworthy information about an engine condition.
2. For reception of exact results of check the engine should be heated-up, the battery is completely charged, and spark plugs are turned out. The help of other person Is required also.
3. Completely disconnect ignition system for what disconnect the central high-voltage wire from a cover of the distributor of ignition, connect it to weight on the block of cylinders.
4. Insert a compression measuring instrument into an aperture for a candle of 1st cylinder. It is preferable to use a measuring instrument with a carving tip.
5. Ask the assistant to squeeze out to the full a pedal throttle заслонки and for some seconds to include a starter. After first two turns коленвала pressure should increase in a measuring instrument to the maximum. Write down the maximum indication of a measuring instrument.
6. Repeat measurements for other cylinders, write down measuring instrument indications.
7. Compression indications in cylinders should be almost identical. If distinction of a compression exceeds norm the engine is faulty. On the serviceable engine pressure should accrue quickly. Low pressure after the first piston stroke and slow increase at the subsequent steps of compression specifies in deterioration of piston rings. If after the first piston stroke pressure low, and at the subsequent steps of compression does not increase, the reason is leak in valves or not tightness of a lining of a head of the block of cylinders (the reason cracks in a head of cylinders also can be). Compression decrease can be caused also deposit adjournment on heads of valves.
8. If pressure in each of cylinders corresponds to the bottom limit, or below this limit through an aperture for a candle enter into the cylinder of a few oil for the engine (about a full teaspoon), then repeat tests.
9. If after oil introduction in the cylinder the compression has raised, it is possible to draw an unequivocal conclusion that walls of cylinders and pistons are worn out. If the compression increases slightly, or will not increase at all leak is caused прогаром valves, or infringement of tightness of a lining of a head of the block of cylinders.
10. If a compression equally low only in two next cylinders most a plausible reason is the lining burn-out between these cylinders. An additional sign is presence at oil of traces of a cooling liquid.
11. If the compression in one of cylinders on 20 % more low than in the others and the engine not absolutely steadily idles, the reason is deterioration of a cam of a cam-shaft of the given cylinder.
12. If value of a compression considerably exceeds norm the combustion chamber is covered by deposit adjournment. In this case a head of cylinders it is necessary to remove and remove a deposit.
13. Upon termination of measurements screw candles and put into place a high-voltage wire.
