FUEL SYSTEM OF INTERNAL COMBUSTION ENGINE Russian patent published in 1999 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: system is designed for preparing and delivering low-viscosity fuel, preliminarily refined and heated high-viscosity fuel, and water-fuel emulsion prepared on their base whose components are oil residues, fuel sediments or oil containing water, into combustion chambers of internal combustion (diesel) engines. System has pipeline connecting pressure branch pipe of fuel feed pump. Suction branch pipe of fuel injection pump is furnished with shutoff member. Fuel system of internal combustion engine includes also high-viscosity fuel service tank inner space of which is furnished with coil heater, pipeline to deliver high viscosity fuel into suction space of fuel feed pump, shutoff members and ejector with ring nozzle connected with pressure pipeline of fuel feed pump. Outlet pipeline of ejector communicates with suction space of fuel injection pump, and suction pipeline of ejector is connected with service fuel tanks, contaminated fuel tank and oil-containing water collecting tank. EFFECT: enhanced ecological and economy characteristics of internal combustion engine, enlarged operating capabilities owing to thermal utilization of oil residues, fire decontamination of oil-containing waters in water-fuel emulsion combusted in engine combustion chamber, enlarged range of fuels combusted in engine by refining low grade oil fuel delivered for combustion. 3 cl, 1 dwg
