FIELD: engines and pumps.
SUBSTANCE: separate liquid system of internal combustion engine cooling comprising a cavity of a head of a cylinder unit and a cavity of a cylinder unit for cooling liquid, pipelines, nozzles, a water pump, a thermostat and a radiator, at the same time the cavity of the head of the cylinder unit is separated from the cavity of the cylinder unit with a gasket for independent forced circulation of cooling liquid in the head of the unit and forced circulation of cooling liquid in the cavity of the engine cylinder unit, circulation is provided by a two-chamber water pump, comprising two impellers, at the same time one chamber is designed for circulation of cooling liquid in the cavity of the head of the unit, the other one - in the cavity of the cylinder unit via its nozzles, pipelines, thermostats, but through a common radiator.
EFFECT: invention provides for stable operation of a valve mechanism under all engine modes.
