    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： The invention relates to an additional process for the spark advance adjustment. This process is used for the tight adjustment of the spark advance angle depending on the structure of the fuel molecules from at least one mapping. This adjustment covers the entire operation range of the engine. This process reduces the pollutant emission when the engine is cold, as soon as the engine starting and stabilisation phase when the engine control and adjustment systems are not in a closed adjustment loop yet. The spark advance adjustment can also be used for operation at the rattle boundary during high load operation and at the engine full load.

    摘要： A fuel detector in communication with an engine control unit and a sensor identifies one of a first and a second fuel type in response to a sensor input. The engine control unit is configured to provide a first fuel injector pulse width in response to first fuel identification by the fuel detector and a second fuel injector pulse width in response to second fuel identification by the fuel detector. The pulse width signal is optimized for a gasoline blend, while the second pulse width signal is optimized for an E85 fuel blend. The second pulse width is from about 25% to 27% greater than the first pulse width.

    摘要： A method and apparatus for operation of an internal combustion engine running under a homogeneous charge compression ignition (HCCI) mode with fuel partially reformed by an onboard fuel reformer. In one embodiment, the onboard fuel reformer is a plasmatron fuel converter. The temperature and composition of the gaseous charge into the cylinders of the engine can be adjusted by mixing the charge into the cylinder (which contains air, exhaust gas and/or unreformed fuel) with hydrogen rich gas from the onboard reformer. The fuel reformer transforms the fuel to a mixture of hydrogen, CO and other light hydrocarbons. By adjusting operation in the reformer, the composition of the reformate can be altered. In addition to thermal management of the cylinder charge, the reformate can be used as a fuel blending agent in order to adjust the octane/cetane number of the air charge and thus control the ignition timing of the overall fuel/air charge to the cylinder.
