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

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: proposed device can be used to improve fuel economy of compression ignition engines. System has reservoir with fuel connected with fuel injection pump. Hermetically sealed flow-through reservoir is installed at pump inlet. Hermetically sealed reservoir is provided with mechanical pump at its inlet. Capacity of reservoir is not less than 0.8 lit per liter of engine displacement. Suction branch pipe of mechanical pump is connected by main line with higher pressure gas source. Reservoir outlet pipeline is connected with inlet of mechanical pump forming recirculating circuit. Controlled safety valve is installed on flow-through reservoir filled from gas source. EFFECT: provision of deep controlled saturation of liquid fuel with dissolved gas with resulting decreased duration and increased completeness of combustion, reduced consumption of fuel. 4 cl, 1 dwg
