Abstract (en)
In a common-rail diesel engine, a fuel pressure setting map is prepared, which allocates a region of equal fuel injection pressure to an equal output region of the engine output determined from engine revolution and engine torque. Thus, it becomes possible to let changes of the heat generation rate approach an ideal state across the entire engine operation region. Moreover, a systematic procedure for controlling the fuel pressure can be implemented that is common to a number of engine types, so that it becomes possible to simplify the preparation of the fuel pressure setting map for setting the suitable fuel injection pressure in accordance with the operation state of the engine.
