INTERNAL COMBUSTION ENGINE WITH METERED OUT STEAM SUPPLY DEVICE Russian patent published in 2002 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: invention can be used in exhaust systems of internal combustion engines to reduced content of toxic matter in exhaust gases, reduce fuel consumption and increase power output. Said internal combustion engine has at least two cylinders with intake and outlet valves and ports in which nonreturn valves are fitted, exhaust gas recirculation main line connected to nonreturn valves and exhaust gas receiving chamber. Device for metered out supply of steam is introduced additionally. Said device has housing with intake valve with spring installed at side of delivery of exhaust gases. Metering device is made in form of cylinder with piston. Cylinder is provided with holes in which shutoff valves are fitted. Intake valve is made for displacement together with piston. EFFECT: improved efficiency of cleaning of exhaust gases, reduced fuel consumption, improved engine temperature conditions owing to metered out supply of steam into exhaust gas recirculation system. 2 dwg
