INTERNAL COMBUSTION ENGINE WITH HEATER UTILIZING HEAT OF EXHAUST GASES Russian patent published in 2001 - IPC

FIELD: mechanical engineering; internal combustion engine. SUBSTANCE: if heater is installed in intake manifold of engine, ignition inside such heater can be provided and back flow of suction air inside intake manifold can be prevented even when engine blower operates. Evaporation-type heater using the heat of exhaust gases is connected according to bypass scheme with passage of flow along air delivery duct, combustion chamber housing and gaseous combustion products discharge duct to engine intake manifold along which suction air is delivered into engine cylinders. Compressor of turboblower is not to be installed on intake manifold section between point of its connection to air delivery duct and point of connection to exhaust gas discharge duct. EFFECT: enhanced reliability of operation. 11 cl, 7 dwg
