摘要： Methods and systems are provided for mitigating loss of engine torque due to cavitation in a fuel pump. One example approach is adjusting engine operation or fuel pump operation based on ambient conditions and a measured engine torque being lower than a desired engine torque after a pre-determined duration. The ambient conditions may include one or more of ambient temperature being higher than a temperature threshold, barometric pressure lower than a threshold pressure, and fuel volatility higher than a threshold volatility.

摘要： A method of controlling fuel injection in a dual fuel engine system includes determining, with a first controller, a diesel injection pulse indicative of a first amount of diesel fuel to be injected into a combustion chamber of the engine and a first timing at which the first amount of diesel fuel is to be injected. The method also includes determining, with a second controller, a combined injection pulse based on the diesel injection pulse. The method further includes injecting the second amount of diesel fuel and the third amount of natural gas into the combustion chamber in accordance with the combined injection pulse. In such a method, injection in accordance with the combined injection pulse results in a combustion event characterized by a second combustion characteristic substantially equal to a first combustion characteristic associated with the diesel injection pulse.

摘要： A device capable of supplying an internal combustion engine with fuel while improving the utilization rate of vaporized fuel. A temporary transition from a third state (primary recovery path FL1: closed, secondary recovery path FL2: closed, second vaporized fuel path VL2: closed, condenser 30: decompressed) to a fourth state (primary recovery path FL1: closed, secondary recovery path FL2: closed, second vaporized fuel path VL2: open, condenser 30: decompressed) is achieved. This temporarily increases an internal air pressure P of a condenser 30, and the kinetic energy of a vaporized fuel V leaked out of a first fuel tank 40 through the second vaporized fuel path VL2 is able to sweep away a first fuel F1 in a liquid state accumulated in a vacuum pump 36 to the first fuel tank 40.

摘要： Methods and systems are provided for integrating a bi-fuel engine with a CVT transmission. Responsive to a driver demand, a controller may determine whether to maintain usage of a current fuel or transition to an alternate fuel based on the cost efficiency of the transition and further based on any engine limitations that may be incurred at the engine speed-load following the transition. To improve the net fuel economy benefit while addressing the engine limitation, a fuel transition may be combined with a CVT adjusted engine speed-load regime, while maintaining engine power output.
