FIELD: engines and pumps.
SUBSTANCE: engine includes unit (1) of cylinders and root supports located between cylinders. In planes of root supports perpendicular to the axis of the crankshaft there made are stiffeners, at least one of which has a hollow shape. Head (6) of cylinders has hollow shapes made as a continuation of hollow shaped of the unit of cylinders. Oil cooler (9) is arranged on the unit of cylinders, and distributing pipe (8) for supply of cooling liquid individually to the head of each cylinder is installed on the side of the head of cylinders from the oil cooler. An engine has water pump (20) to provide circulation. Supply devices of cooling liquid from oil cooler (9) to distributing pipe (8) represent through channel (19) in unit (1) and head (6) of cylinders, which passes from oil cooler (9) in the plane at least of one of the root supports.
EFFECT: reducing the list of parts and simplifying the engine design.
