Abstract
A fuel injection device is provided with a fuel injection valve to inject fuel into a combustion chamber of an engine, and an electronic control unit to operate the fuel injection valve to inject the fuel in multiple separate injections. The electronic control unit controls a timing of a first fuel injection by the fuel injection valve to carry out the first fuel injection on the retard side with respect to a timing when a premix duration immediately after the first fuel injection is minimum, and controls a timing of a second fuel injection by the fuel injection valve in such a manner that a heat release rate waveform produced by the first fuel injection and the second fuel injection carried out thereafter has a double-peaked shape.
