3.5.7. Compression check


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

The engine at check should be warmed up.
1. Turn out glow plugs. Besides, removal of tubes of injection from nozzles is required.
2. Insert the device for compression measurement into the first candle opening and ask the assistant to start a starter, having pressed against the stop 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 a compression in other cylinders.
5. Any of cylinders should not have a compression, a component less than 80 % from the maximum measured value. Decrease and various values of a compression in cylinders can be carried to worn-out piston rings that should be accompanied by the raised consumption of oil at the same time.
6. At normal operation of cylinders the compression should be 27,0 bar. A wear limit – 24,0 bar. The maximum difference between separate cylinders – 3,0 bar.
