Abstract
An engine control apparatus comprised of an engine control ECU has a program preloaded therein for determining a combustion rate (actual combustion rate) corresponding to the ratio of an ideal heat generation quantity (target heat generation quantity) estimated to be generated from a fuel supply quantity, and an actual heat generation quantity actually generated by the fuel supply quantity. The engine control apparatus controls pilot injection timing with a controlled variable corresponding to the thus determined combustion rate so as to increase the combustion rate.
Claims21
An engine control apparatus for controlling a target engine of the type having an output shaft rotatably driven by a torque generated on the output shaft through combustion of fuel inside a cylinder of the engine, the engine control apparatus comprising:
- a combustion rate determining means for determining a combustion rate corresponding to the ratio of a target heat generation quantity, which is an ideal heat quantity estimated to be generated from a fuel supply quantity, and an actual heat generation quantity, which is a heat quantity actually generated from the fuel supply quantity.
