DEVICE TO REGULATE TEMPERATURE OF WORKING MEDIA IN INTERNAL COMBUSTION ENGINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: invention can be used for automatically regulate temperature of working media in internal combustion engines of vehicles, namely in cooling, supercharging air and fuel systems. Proposed device contains electric temperature transmitter installed at engine outlet and connected with control unit coupled through electric actuator with three-way valve whose branch pipes are connected with engine working medium intake channel, bypass channel to engine and channel re-distributing working medium flow, to heat exchanger. Device contains additionally, load pickup installed on engine and microcomputer with compensating, comparing-summing and regulating units. Comparing-summing unit is connected with temperature transmitter, load pickup and setter. Invention provides quick and accurate control of cooling water optimum temperature at variable loads owing to quick response of device elements and introduction of combination control. EFFECT: improved control of temperature. 2 cl, 1 dwg
