摘要： A method for operating a fuel system for an internal combustion engine operated with fuel gas. The fuel system has at least one electrically actuated shutoff valve (4) and at least one electrically operated heating device (14, 16). The operating method includes: generating a signal to turn on the heating device (14, 16) when the internal combustion engine is turned on; determining a heating demand (nullreference) of the fuel system when the heating device (14, 16) is turned on; and depending on the heating demand (nullreference) of the fuel system, determining a delay time between the time the heating device (14, 16) is turned on and the time the shutoff valve (4) is opened. The heating demand (nullreference) can be a function of a temperature (Tengine coolant) of the engine and/or a temperature (Thydraulic fluid) independent of the engine and/or the current (Iheating) flowing through the heating device.

摘要： A vaporized fuel injection system for a combustion engine that includes a fuel vaporization chamber and a two-way valve. The fuel vaporization chamber has a chamber input and a chamber output, and is connected with a fuel source via the chamber input. The fuel vaporization chamber is for vaporizing fuel input to the chamber input and outputting vaporized fuel to the chamber output. The two-way valve has first and second valve inputs and an valve output. The first valve input is connected to the chamber output, and the second valve input is connected to the fuel source. The two-way valve is switchable to allow fuel to flow from only one of the first or second valve inputs to the valve output.

摘要： The invention is in a regulator and converter operated to fumigate a volatile material, preferably a liquified petroleum gas (LPG), under vacuum, into an intake air flow of an internal combustion diesel engine to provide, on demand generated by an operator closing a throttle, passage of LPG to the regulator and converter wherein it is vaporized and the LPG vapors are passed into the engine intake air flow that travels into the engine. The injection of LPG vapors provides for an increase in engine output power and an improvement in fuel percentage of burn. The regulator and converter is connected the engine coolant system to receive a hot coolant flow, heating an LPG flow path therethrough to vaporize the LPG with the LPG vapors then directed from the regulator and converter into the engine intake air flow. With the control of LPG passage to the regulator and converter controlled by operation of an LPG cutoff valve that is operated responsive to a presence of a system as sense by high and/or low pressure switches.

摘要： A natural gas engine capable of exhaust emission control over the entire temperature range and at low costs without requiring a complicated structure. An adsorbent (7) is disposed between a fuel tank (4) and a fuel supply port (5) on a suction air passage (2), and NMOG in the fuel gas supplied to the fuel tank (4) is adsorbed by the adsorbent (7) to purify the fuel gas in advance. When the temperature of a catalyst (11) disposed on an exhaust passage (3) reaches an activation temperature, the adsorbent (7) is heated by a heater (9) to a desorption temperature to desorb NMOG from the adsorbent (7) and purify the NMOG by the catalyst (11).

摘要： A first cutoff valve 24 and a second cutoff valve 41 are closed in a state in which an internal combustion engine 1 is stopped, and a reducing amount of a pressure P0 in a high pressure passageway 11 after the passage of a predetermined decision time T0 and a reducing amount of a pressure P2 in a low pressure passageway 12 after the passage of a predetermined decision time T2 are measured. When the reducing amount of the first pressure P0 is equal to or larger than a predetermined reducing amount &Dgr;P0, it is decided that a leakage is generated in the high pressure passageway 11. When the reducing amount of the second pressure P2 is equal to or larger than a predetermined reducing amount &Dgr;P2, it is decided that a leakage is generated in the low pressure passageway 12.
