  • OPERATING METHOD FOR AN INTERNAL COMBUSTION ENGINE WHICH CAN BE SELECTIVELY OPERATED BY MEANS OF A LIQUID FUEL AND A GASEOUS FUEL, AND FUEL SUPPLY SYSTEM
    Publication number: 20090320774
    Abstract: The invention relates to an operating method for an internal combustion engine which can be selectively operated by means of a liquid and a second fuel, in particular a gaseous fuel, wherein in operation of the internal combustion engine with the second fuel, in particular in the gas-operating mode, at least one temperature-loaded component of the internal combustion engine is cooled with the liquid fuel. The invention also relates to a fuel supply system for an internal combustion engine which can be operated by means of liquid and gaseous fuels.

  • Fuel system for an LPG engine
    Patent number: 6976455
    Abstract: A fuel system for an internal combustion engine (12) operated with fuel gas includes an evaporator (1) in which the liquid fuel gas is transformed by the addition of heat into a gaseous state. The evaporator (1) has a first heating device (13) configured to transmit a portion of the waste heat of the internal combustion engine (12) to the fuel gas in the evaporator (1). The evaporator (1) has a second heating device, by means of which the fuel gas in the evaporator (1) can be heated regardless of the condition of the internal combustion engine (12). The second heating device (14) can include an electrical heating element, e.g., a PTC heating element.
