FIELD: engines.
SUBSTANCE: invention can be used in internal combustion engines with supercharging and liquid cooling. Engine (1) has at least one cylinder block head (1a), which at unit end side (1c) is connected to cylinders block (1b). Cooling loop (2) consists of cooling liquid supply pump (2a), heat exchanger and ventilating vessel (2b). There is at least one supercharger (3), operating from exhaust gases, where compressor and turbine are arranged on one shaft. Supercharger (3) shaft is installed in liquid cooled bearing housing (4). To form liquid cooling system bearing housing (4) is connected to engine (1) cooling loop (2) by means of connecting line (5). Bearing housing (4) is located between pump (2a) and ventilating vessel (2b). Connecting line (5) leads into ventilating vessel (2b), which, in addition to cooling liquid (2e) volume, also contains volume of gas at point (2d), on which cooling fluid acts. Radiator (6) is located in connecting line (5) between pump (2a) and bearing housing (4).
EFFECT: technical result consists in prevention of coolant intermittent feed into ventilating vessel.
