Measuring instrument of a compression for petrol engines

Compression check in cylinders of petrol engines

1. Warm up the engine to normal working temperature.
2. Turn out candles.
3. Disconnect from the ignition coil a high-voltage wire.
4. Completely open throttle заслонку.
5. Screw in an aperture for a candle of 1st cylinder a compression measuring instrument.
6. Ask to press the assistant a pedal throttle заслонки and to include a starter (on carburettor and инжекторных engines). The starter should join two-three times for short time.
7. Define the indication of a manometre in the end of each inclusion of a starter and write down the maximum indication. Repeat procedure for each cylinder. Values of a compression in cylinders should be 10,3–11,7 атм (limiting 7,2 атм). Values of a compression in отельных cylinders should not differ more than on 10 %.
8. If a compression below norm fill in in the cylinder about 1 table spoon of oil for the engine and repeat measurements. If the compression has increased, it specifies in deterioration or breakage of piston rings, or the strengthened deterioration of walls of the cylinder. If pressure has not changed, the reason is leaky прилегание valves to saddles (repair клапанного the mechanism is required), or damage of a lining of a head of the block of cylinders near to the cylinder. If low value of a compression in two next cylinders which does not change at oil addition the lining of a head of cylinders is damaged is observed.

Measuring instrument of a compression for diesel engines

Procedure of check differs nothing from described above, but has the features.

Compression measurement on diesel engines

1. For diesel engines it is necessary to use a special measuring instrument of a compression, расчитанный on ready more a high pressure.
2. It is necessary to remove tubes from all cylinders and atomizers with ring linings.
3. Track, that the valve for стравливания air on a compression measuring instrument has been closed.
4. At installation of atomizers replace ring linings.
