A fuel injection controller of a diesel engine calculates a requirement injection amount based on an operation amount of an accelerator pedal and rotation speed of the engine. The fuel injection controller divides the requirement injection amount into multiple injections. Injection amounts of the divided injections are set to monotonically increase with respect to an order of the injections. Thus, even if a simple fuel injection device is used, the fuel injection controller can suitably achieve both of reduction of a discharge amount of nitrogen oxides and reduction of fuel consumption.
