3.4.9. Compression check in cylinders of engines
GENERAL INFORMATION

Compression measuring instrument for petrol engines

Compression check in cylinders of petrol engines

PERFORMANCE ORDER
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 a butterfly valve.
5. Screw in an opening for a candle of the 1st cylinder a compression measuring instrument.
6. Ask the assistant to press a pedal of a butterfly valve and to include a starter (on carburetor and injector engines). The starter should join two-three times for short time.
7. Define the manometer indication at 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 atm (limiting 7,2 atm). Values of a compression in hotel cylinders should not differ more than for 10 %.
8. If the compression is lower than norm, fill in in the cylinder about 1 tablespoon of oil for the engine and repeat measurements. If the compression increased, it indicates wear or breakage of piston rings, or the strengthened wear of walls of the cylinder. If pressure did not change, the reason is the leaky prileganiye of valves to saddles (repair of the klapanny mechanism is required), or damage of laying of a head of the block of cylinders near the cylinder. If low value of a compression in two next cylinders which does not change at oil addition is observed, laying of a head of cylinders is damaged.

Compression measuring instrument for diesel engines

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

Compression measurement on diesel engines
PERFORMANCE ORDER
1. For diesel engines it is necessary to use the special measuring instrument of a compression calculated on much more high pressure.
2. It is necessary to remove tubes from all cylinders and nozzles with ring laying.
3. Track, that the valve for an air stravlivaniye on a measuring instrument of a compression was closed.
4. At installation of nozzles replace ring laying.
