摘要： Various control strategies and techniques for controlling a variable speed fan in an internal combustion engine are provided. The various control techniques improve fuel economy by operating the fan at a speed sufficient to cool the engine, while avoiding unnecessarily higher speeds that result in poor fuel economy. Further, the fan may be completely disabled at cold start up to avoid over cooling, particularly in an engine using a charge air cooling system.

摘要： A method of controlling an internal combustion engine having a variable speed fan includes controlling the variable speed fan with closed loop control based on fan motor hydraulic pressure. A reference fan pressure is based on an applied fan request signal. The actual fan motor pressure is monitored, and an error signal is determined by comparing the reference fan pressure to the actual fan pressure. The fan is driven based on the error signal.

摘要： An engine controller capable of operating in both a torque governing mode and a speed governing mode simultaneously, and a method of operation whereby speed governing may be enabled and disabled while simultaneously providing a valid speed request signal to the controller is disclosed. A speed governor signal having an enabled state and a disabled state is generated external to the controller and monitored by the speed governor. A speed request signal is simultaneously monitored by the speed governor. The speed governor is operative to control the speed of the engine proportional to the speed request signal while the speed governor signal is in the enabled state. The speed governor is disabled by setting the speed governor signal into the disabled state. A torque governor may also be operational within the controller. The torque governor monitors a torque request signal which it uses to control a torque generated by the engine.

摘要： A system and method for controlling engine speed of an internal combustion engine provide automatically returning to a set speed selected with a hand throttle after operating at idle or near idle. The system and method are particularly suited for operation in driving a mud pump used in petroleum drilling applications where the operator dials-in a desired operating speed corresponding to a desired pumping rate. The engine is returned to idle or near idle to allow additional sections of pipe to be added. The engine then automatically returns to the previously selected set speed without additional manipulation of the hand throttle. In one embodiment, dual hand throttles are provided to support remote station operation and control of the engine speed.
