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

FIELD: multifuel engines. SUBSTANCE: system has low-viscosity fuel pipeline, high-viscosity fuel pipeline, mixer, high-pressure fuel injection pump, storage battery, electrohydraulic dosing apparatus, logic control device, injector, and thermoelectric cooler. It also has temperature sensors of injector, load, and control console, those of atmospheric pressure and fuel position, power unit, fuel feed ducts running to injectors and cooling system. Upon engine starting, system delivers accurately metered amount of fuel to engine cylinders. Optimal timing angle is simultaneously set depending on load, kind of fuel, and atmospheric pressure. When engine uses low-viscosity fuel, thermoelectric cooler maintains optimal temperature of injector atomizer. EFFECT: provision for setting optimal timing angle depending on load, atmospheric pressure, and kind of fuel. 3 cl, 1 dwg
