INTERNAL COMBUSTION ENGINE SUPERCHARGING AIR TEMPERATURE REGULATOR Russian patent published in 2002 - IPC

FIELD: mechanical engineering; cooling systems of internal combustion engines. SUBSTANCE: device has turbocompressor delivering air through distributor with three channels supplying supercharging air into engine. Two channels are connected with engine through heat exchangers. One of these heat exchangers is designed for cooling supercharging air is connected to outboard water inlet and outlet channels, and other heat exchanger is designed for heating supercharging air and is connected to heating source. According to invention, device is additionally furnished with electric psychrometer and its transmitter installed on engine supercharging air supply channel and electromagnetic valve installed on outboard water supply channel and electric actuator connected to supercharging air distributor and electrically coupled with electronic control unit. EFFECT: improved efficiency of engine operation by preventing condensation of moisture in heat exchanger and maintaining temperature of supercharging air above dew point at partial loads of engine in operation. 2 cl, 1 dwg
