INTERNAL COMBUSTION ENGINE SUPERCHARGING AIR TEMPERATURE CONTROL SYSTEM Russian patent published in 2005 - IPC

FIELD: mechanical engineering; engines.

SUBSTANCE: invention relates to systems providing automatic control of supercharging air temperature in internal combustion engines. Proposed system contains turbocompressor, cooling system, electric actuator, four-way cock, gas distributor, electric distributor of exhaust gases, channels to supply supercharging air to cooler and heat exchanger, channel to deliver air into engine, reservoir with liquid cooling agent, and meter. System is coupled with program-controlled engine cooling system through four-way cock with electric actuator coupled with control unit whose input is connected through bypass channel at partial loads to supercharging air heat exchanger, and output is connected to engine. Channel to let out exhaust gases from gas distributor, electromagnetic valve and dew point control device are also provided. Invention makes it possible to chosen supercharging air working temperature and maintain chosen preset temperature conditions at partial loads of engine and at nominal loads in hot climate.

EFFECT: enlarged operating capabilities.
