AUTOMATIC SYSTEM FOR EXTREME CONTROL OF TEMPERATURE OF HEAT ENGINE SUPERCHARGING AIR Russian patent published in 2009 - IPC F02B29/04 

FIELD: engines and pumps; heating.

SUBSTANCE: automatic system comprises heat exchanger of supercharging air cooled by liquid pumped by the first engine and distributed by three-way relief valve with drive between the first radiator connected to heat exchanger and blown with air supplied by the first fan with drive, and the second radiator connected to heat engine and the second pump and blown with air supplied by the second fan with drive, detector of supercharging air temperature installed on forcing manifold between heat exchanger and heat engine, detector of cooling air temperature, detector of cooling liquid temperature, detector of heat engine shaft rotary speed, torque detector on the shaft of heat engine, fuel consumption detector, controller of heat engine shaft rotary speed, control unit, at that control unit is connected to heat engine by means of controller of heat engine shaft rotary speed, at that system additionally comprises the following components: multiplication unit, to which detector of shaft rotary speed and detector of shaft torque are connected; division unit, to which multiplication unit and fuel consumption detector are connected; unit for searching of fuel consumption extremum by heat engine, which corresponds to optimal temperature of heat engine supercharging air, with introduced system of automatic extremum searching, to which multiplication and division units are connected, and also the first setting device of supercharging air temperature; the first adding device, to which detectors of supercharging air and cooling air temperature are connected, as well as multiplication unit and the first setting device, and also drives of three-way relief valve and the first fan; the second adding device, to which detector of cooling air temperature and detector of heat engine cooling fluid are connected, as well as multiplication unit and the second setting device, and also drive of the second fan.

EFFECT: minimum fuel consumption, higher reliability of heat engine and lower exhaust of hazardous substances with exhaust gases.
