    摘要: An internal combustion engine includes a cylinder having a cylinder inner surface, a cylinder head that cooperates with the cylinder inner surface to define a combustion chamber and has a head inner surface including an intake opening through which an intake gas is introduced into the combustion chamber, an intake valve that opens and closes the intake opening, an ignition plug provided on the cylinder head, and an intake drifting mechanism that causes the intake gas to drift toward an axis of the cylinder in the intake opening and generates a vortex flow in the combustion chamber. When the intake valve is opened, a minimum gap between the intake valve and the head inner surface is equal to or larger than a gap between the intake valve and the cylinder inner surface in a diametrical direction of the cylinder.

    摘要: An internal combustion engine includes an engine body including a cylinder that defines a combustion chamber, an intake opening that faces the combustion chamber, and an intake passage in communication with the combustion chamber through the intake opening, a piston provided in the cylinder, an intake valve that opens and closes the intake opening, a throttle valve provided in the intake passage, and an injector that injects fuel between the throttle valve in the intake passage and the intake opening. A ratio of a volume of the portion that extends from the throttle valve in the intake passage to the intake opening, to a stroke volume of the cylinder is at most approximately 0.61. The time period in which fuel injection from the injector is terminated during an idling operation is set within a period of time after one intake stroke has been completed and before the next intake stroke is begun.
