    摘要: A method for adjusting fuel injection timing in an internal combustion engine including a cylinder and configured to operate multiple fuel injections in the cylinder per combustion cycle includes monitoring in-cylinder pressure through a first combustion cycle, determining actual combustion phasing metrics based upon the in-cylinder pressure, monitoring a baseline fuel injection timing comprising a first injection timing and a second injection timing, providing expected combustion phasing metrics based upon the baseline fuel injection timing, comparing the actual combustion phasing metrics to the expected combustion phasing metrics, and adjusting the baseline fuel injection timing in a second combustion cycle based upon the comparing.

    摘要: A method and system for adaptively controlling a diesel engine to account for variations in the cetane number of the diesel fuel being used. An engine controller includes various control modules with algorithms for estimating the fuel cetane number, or determining the ignition delay that the engine is experiencing, or both. With this information, the controller can adjust the amount of exhaust gas recirculation that is used, thus varying the amount of oxygen that is available in the intake charge to burn the fuel. The controller can also adjust the timing of the fuel injection event, as another way of altering the nature of combustion. Using these techniques, the controller can optimize the engine operation based on the fuel currently being used.

    摘要: An engine is fueled with a fuel blend of diesel and bidiesel fuel. A feed forward fuel control term is provided corresponding to a 100 percent diesel fuel blend and a feedback fuel control term corrects for lambda deviations resulting in a final fuel control term. During regeneration of a lean Nox trap, the feed forward fuel control term is adapted with a factor as a function of the feed forward fuel control term and the final fuel control term.
