    摘要: An electronic microcomputer based engine brake control device and a method for controlling an engine compression brake is disclosed. An algorithm for enabling engine brake operation includes monitoring a brake enable switch, engine RPM, engine fueling rate, cruise control or power takeoff system activation state, throttle position, manifold pressure and clutch pedal position. Engine brake operation is fully automatic and operates in a safe manner according to the disclosed algorithm.

    摘要: A control system for controlling fueling and/or timing of a fuel injector in an internal combustion engine. Fuel injection is controlled based upon the recent operating history of the engine. In particular, the difference between the instantaneous speed and the average speed over a previous predetermined period are compared and the difference is utilized in determining a control variable which in turn can be used for selecting fueling and/or timing values. The difference between the instantaneous fueling and the average fueling over a predetermined period can also be used in selecting the control variable. The fuel injector fueling and/or timing is determined utilizing fueling and/or timing values from at least two maps, with the control variable determining the proportions of the timing/fueling valves to be utilized in determining commanded timing/fueling. The control variable may also be set to a fixed value under certain conditions such as during operation on a governor, or where the operator selects an override function.
