  • Methods and systems for controlling a fueling strategy for internal combustion engines
    Patent number: 11401884
    Abstract: A method for controlling fuel injection aspects of a fuel system of an internal combustion engine includes determining a fuel injection strategy for each engine cycle including a pilot fuel injection, a main fuel injection, and a dwell time between the pilot and main fuel injections. The method also includes automatically adjusting the dwell time for each engine cycle based on a sensed ambient temperature and ambient pressure associated with the internal combustion engine.
