ABSTRACT:
An engine control apparatus for a multi-cylinder compression ignition internal combustion engine includes a combustion status sensor and a controller. The combustion status sensor is installed in a selected one of cylinders of the engine. The controller works to sample an output from the combustion status sensor to determine a combustion status parameter and determine injection timings so as to bring the combustion status parameter into agreement with a target value. The controller also corrects the injection timing for at least one of the cylinders in which the combustion status sensor is not installed so that a combustion status parameter of the at least one of the cylinders lies on an advanced side of that of the one of the cylinders in which the combustion status sensor is installed, thereby avoiding the deterioration of quality of combustion of the fuel arising from a shift of the time of the ignition in the retarded direction from a desired time point.
