FIELD: engines and pumps.
SUBSTANCE: group of inventions relates to engine production, particularly to engines control by individual cylinders switching off. Summary of invention consists in fact, that in three-cylinder single row piston internal combustion engine 5 consisting of three cylinders 11, 12 and 13, inner cylinder 12 can be selectively deactivated to save fuel consumption or for additional engine warming up, for example, due to exhaust gases temperature increasing for after-treatment device warming up. Engine 5 has crankshaft 40 with cranks arranged in one plane with three elbows 11T, 12T, 13T. Elbows 11T, 13T for two outer cylinders 11, 13 match in phase, and elbow 12T for inner cylinder 12 is displaced by 180 degrees. Inner cylinder 12 can be deactivated by switching off fuel supply to cylinder 12.
EFFECT: technical result is increasing engine efficiency.
