Abstract
A control apparatus (): creates a torque correction table indicating a relationship between a change rate of an intake air amount, a change of the main injection amount and the main injection timing of a fuel injection apparatus () in the torque value of a diesel engine () in a lean state; measures an intake air amount in a rich state by using an MAF sensor (); calculates a change rate of the measured intake air amount for the intake air amount in the lean state; obtains a correction value of the main injection amount and a correction value of the main injection timing of the fuel injection apparatus () based on the calculated change rate and the torque correction table; and performs an injection of the fuel in the rich state at the main injection amount and the main injection timing, corrected by the respective correction values.
