(54)	Transient injection quantity control apparatus and method of diesel engine

(57) Even in the course of executing smoothing process of fuel injection quantity of a diesel engine (1), the increase in a basic fuel injection quantity is switched to the increased quantity having a smaller increase rate depending on an accelerator opening degree and a driver's request for deceleration so as to improve drivability by intensifying the response to the driver's request for acceleration. As a result, even in the course of executing the acceleration smoothing control, the acceleration can be suppressed in quick response to the driver's request for deceleration to be immediately satisfied, resulting in excellent drivability.
