Abstract:
A method for controlling a turbocharged compression-ignition engine during a full or high load condition, the engine having an intercooling system that uses a predetermined coolant fluid, the engine being configured to receive a predetermined combustion-supporting fluid into a plurality of cylinders through a respective intake manifold, the method comprising:detecting the presence of the full and/or high load condition of the engine;sensing a parameter indicative of a respective ambient condition;selecting a desired value of a respective operational parameter that influences peak pressures developed within the cylinders, the desired value being selected based on the value of the parameter indicative of the respective ambient condition;comparing an actual value of the operational parameter against the desired value of that operational parameter; andselectively actuating the intercooling system based on the results of the comparison step to adjust the actual value of the operational parameter to contain the peak cylinder pressures.
