PROBLEM TO BE SOLVED: To inhibit fuel injected from a fuel injection valve and attached to the inner wall face of an intake passage from moving to the downstream side of the intake passage.MEANS FOR SOLVING THE PROBLEM: A first plasma actuator 20A is provided in a region R on an inner wall face 6A of an intake passage 6, where fuel H injected from a fuel injection valve 19 is attached. The first plasma actuator is arranged to generate a first air stream FA in a predetermined direction not including a component in the direction of moving to the downstream side of the intake passage, during its operation. A control unit allows the operation of the first plasma actuator in at least a partial period out of a period from when the fuel injection of the fuel injection valve is started to when the opening of an intake valve 7 is started.SELECTED DRAWING: Figure 5 |
