INTERNAL COMBUSTION ENGINE WITH HEAT RECOVERY Russian patent published in 2014 - IPC F02G5/00 

FIELD: engines and pumps.

SUBSTANCE: engine comprises cylinder accommodating piston, liquid cooling system with pump and radiator. In compliance with this invention, air-fuel mix feed system accommodates three heat exchangers: First, second and third. Note here that first heat exchange inlet is connected via pipe with radiator inlet, while its outlet is connected via return pipe with radiator outlet. Second heat exchanger inlet is connected via pipe with silencer inlet, while its outlet is connected via pipe with silencer outlet. Third heat exchanger inlet is connected via high-pressure line with the pump while its outlet is connected via return line with oil pan. Flow rate regulator can be arranged between pump and radiator and be completely closed. Invention allows the recovery of cooling and discharge systems heat.

EFFECT: higher efficiency and reliability, non-polluting design.
