Abstract
A diesel engineis provided with a common rail type fuel injection device. A controllercontrols a common rail pressure and an engine control parameter other than the common rail pressure, respectively, to target values that are determined on the basis of the engine load. The controllercorrects the engine control parameter other than the common rail pressure when the common rail pressure does not coincide with the target common rail pressure in a transient state of the diesel engine, thereby preventing an air-fuel ratio in the combustion region from becoming lean.
