Compression checkCompression check allows to draw a conclusion on an engine condition. During check it is possible to establish, whether valves and pistons (piston rings) are serviceable or they are worn out. Besides, results of check show, whether it is necessary to replace the engine or it is necessary for repairing. For check it is necessary компрессометр.
The difference between values of pressure of a compression of separate cylinders should not exceed 1.0 bar at the petrol engine, and 3.0 bar at a diesel engine.
If one or several cylinders in comparison with others have the pressure different on higher value, it specifies in damage of valves, deterioration of piston rings or damage of a lining of a head of cylinders. In this case it is necessary to repair or replace the engine.
The pressure size is of secondary importance, as it depends among other on the applied measuring device. At petrol engines it should not be less than 10 bar.
