摘要
A method and system for controlling a compression ignition engine in railroad locomotives and other land or marine-based large propulsion or power generation equipment operable in a selected one of a plurality of engine throttle notches is provided. Each throttle notch is indicative of a respective load condition of the engine. The engine has an intercooling system using a predetermined cooling fluid and the engine is configured to receive a predetermined combustion-supporting fluid (e.g., air) into a plurality of cylinders through respective intake manifolds. The method allows for sensing the selected throttle notch, and for selectively actuating the intercooling system to adjust a predetermined operational parameter (e.g., intake manifold air temperature) based on the sensed throttle notch and/or environmental conditions.
