INTERNAL COMBUSTION ENGINE WITH HEAT REGENERATION Russian patent published in 2014 - IPC F02M31/14 

FIELD: engines and pumps.

SUBSTANCE: invention relates to the field of propulsion engineering, namely, to heat recycling mechanisms. The substance of the invention consists in the fact that a heat exchanger of a liquid cooling system is installed in a system of fuel and air mixture injection. A supercharge system may be arranged with a fan and its drive upstream the heat exchanger. The cooling liquid is taken from the cavity of the engine cooling system and is supplied to the injection system heat exchanger. The heat of the cooling system taken by air arriving to the cylinder is recycled.

EFFECT: increased efficiency, reliability and environmental compatibility of an engine.
