Estimating the term…
A diesel engine (10) wherein both the operating speed of the engine (RPM) and the timing of the fuel injection into the engine (AA) are cooperatively controlled to be responsive to both the temperature and the pressure of the air (30) used for combustion. A controller (44) receives a temperature signal (28), an air pressure signal (36), and a power demand signal (24) and executes control logic to produce a fuel injection control signal (46) and an engine speed control signal (48) for controlling a fuel injection system (16). A control strategy based on engine inlet air temperature and pressure or manifold air density may be useful for variable speed and power applications. For applications with discreet speed and power points, such as a locomotive, a speed and timing control strategy based on ambient temperature and pressure is useful for maximizing power during high altitude and/or high ambient/inlet air temperature operation.
A multi-cylinder diesel engine providing enhanced performance in high ambient temperature and high altitude conditions comprising:
A microprocessor product comprising a computer-accessible imbedded software program for controlling a large, medium-speed, multi-cylinder diesel engine in extreme environmental conditions, the processor program regulating a fuel injection system of the engine to cooperatively control both an engine speed and a timing of fuel injection into cylinders of the diesel engine to be responsive to measurements of both a temperature and a pressure of air used for combustion in the engine.
A method of controlling combustion in a large, medium-speed, multi-cylinder diesel engine having discrete throttle settings for enhanced engine performance, including in extreme environmental conditions, the method comprising:
