ABSTRACT:
A fuel injection control device of a diesel engine performs a learning injection during a no-injection period, in which a command injection quantity is zero or under. A difference between a variation in the engine rotation speed in the case where the learning injection is performed and a variation in the engine rotation speed in the case where the learning injection is not performed is calculated as a rotation speed increase. A torque proportional quantity is calculated by multiplying the rotation speed increase by the engine rotation speed at the time when the learning injection is performed. An injection correction value is calculated from a deviation between the actual injection quantity, which is estimated from the torque proportional quantity, and the command injection quantity. The command injection quantity is corrected based on the injection correction value.
