ABSTRACT:
An internal combustion engine includes a valve operating device operatively connected to a pair of intake valves and capable of opening and closing one of the intake valves in accordance with the operating condition of the engine and opening and closing the other intake valve in a small lift amount, thereby producing a deflection of the intake air drawn into the combustion chamber, and a fuel injection valve for injecting a fuel toward the pair of intake valve bores that are independently opened and closed by the intake valves, respectively. The timing of the opening and closing of the intake valve that is opened and closed only in the small lift amount is set at a time point such that the lift amount is maximized in the first half of the intake stroke of the piston. This promotes the atomization of the fuel which is being drawn in with the intake air by the opening of the intake valve opened and closed in the small lift amount, and to enhance the combustibility in the combustion chamber.
