ABSTRACT:
In fuel injection control, an injection pattern is determined by reading, from memory, an injection pattern appropriate to a current engine speed, desired torque, and a common rail pressure. Therefore, it is possible to form “an injection pattern for obtaining an appropriate combustion state,” irrespective of response delay in the common rail pressure. Since the injection pattern appropriate to the current engine speed, the desired torque, and the common rail pressure is read from the memory, data to create “an injection pattern for obtaining an appropriate combustion state” is taken in a one-step process of “map read.” Therefore, it is possible to reduce the calculation load, which is necessary for the injection control.
