3.5.7. Compression check


Compression decrease can be result of not closed valve broken or the worn out piston ring or other damages to the cylinder. It is necessary to make compression check for an establishment of the cylinder which is the reason of pressure decrease of a compression in order to avoid fallacies in all cylinders.

The engine at check should be разогретым.
1. Turn out candles накаливания. Removal of tubes of injection from atomizers Besides, is required.
2. Insert the device for compression measurement into the first candle aperture and ask to start the assistant a starter, having pressed against the stop on a gas pedal.
3. Turn the engine before achievement of the maximum value on a device scale. Press the button on the device to prepare the device for measurement on other cylinder.
4. In the same way check up a compression in other cylinders.
5. Any of cylinders should not have the compression making less of 80 % from the maximum measured value. Decrease and various values of a compression in cylinders can be carried to the worn out piston rings that should be accompanied by the raised expense of oil simultaneously.
6. At normal work of cylinders the compression should be 27,0 bar. A deterioration limit – 24,0 bar. The maximum difference between separate cylinders – 3,0 bar.
