3.2.4. Check of a compression in engine cylinders
Results of check of a compression in cylinders of the engine allow to judge a condition of group of details in the top part of the engine (pistons, rings, valves and laying of a head of the block of cylinders). Namely, reduction of a compression can be caused by leakage of combustion chambers owing to wear of piston rings, damage of heads of valves and saddles, a progar of laying of a head of the block of cylinders.
