GENERAL INFORMATION

The compression and difference of its values on cylinders shows degree of wear of the engine. It is better to take measurement of a compression at service station.

Definition of degree of wear of the engine on a compression


Engine
Compression, MPa
New engine
Wear limit
Maximum permissible difference of values in cylinders
Petrol 1,0 l, 37 kW and 1,4 l, 50 kW
not lower than 1,2
0,75
no more than 0,3
Diesel 1,9 l, 74 kW
2,5 – 3,1
1,9
