SYSTEM AND METHOD FOR ENGINE OPERATION

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.
