Compression measurement

The compression size shows, in most cases, the tsilindro-piston group of the engine is worn how much out.

For compression measurement than 30 bar is necessary компрессометр for diesel engines with the maximum indications not less.

1. Completely to charge the accumulator. To adjust backlashes of valves. The engine to warm up to working temperature.
2. To disconnect a food of candles накаливания and a socket of the electromagnetic valve of giving of fuel.
3. To remove one of candles накаливания and in a candle nest to screw transitive the union компрессометра.
4. To turn a cranked shaft a starter some times. To fix the maximum value of pressure of compression.
5. To repeat measurements on other three cylinders.
6. Compression decrease in all cylinders specifies in deterioration of cylinders, rings and pistons more often.
7. The lowered compression in one of cylinders means damage of plates and saddles of valves, a burn-out or cracks in the piston, damage of a lining of a head of the block of cylinders or a crack in a head of the block of cylinders.
8. The lowered compression in two next cylinders means damage of a lining of a head of the block of cylinders between cylinders more often.
