  • Systems and methods for an engine
    Patent number: 11536216
    Abstract: Various systems and methods are provided for adjusting operating parameters of an internal combustion engine. In one example, a system may include adjusting an amount of advance of a fuel injection timing of a plurality of fuel injectors of an internal combustion engine relative to top dead center (TDC) responsive to engine output demand, where, as the engine output demand increases, the amount of advance first decreases and then increases. In this way, an amount of vehicle emissions may be decreased while an amount of fuel consumption is decreased.
    Type: Grant

  • System and method for engine operation
    Patent number: 11421621
    Abstract: Systems and methods for operating an engine and controlling engine parameters over a range of ambient temperature conditions are provided. A method for an engine includes selecting one or more of an engine speed, an engine load, a base timing, and a fuel common rail pressure from a pre-calibrated engine map corresponding to a selected throttle level and modifying the one or more of the engine speed, the engine load, the base timing, and the fuel common rail pressure based on sensed environmental conditions.
