A cylinder injection valve that injects fuel inside a cylinder and an intake passage injection valve that injects fuel inside an intake passage are provided. When it is determined that deposit greater than or equal to a predetermined amount accumulates, the fuel is forcibly injected by the cylinder injection valve (deposit removing control). The deposit removing control is performed when a pressure of the fuel supplied to the cylinder injection valve is greater than or equal to a predetermined value and an engine load is relatively high. On the other hand, the deposit removing control is not performed when the pressure of the fuel supplied to the cylinder injection valve is greater than or equal to the predetermined value and the engine load is low.
