Abstract
Fuel injection technology of an internal combustion engine is configured in such a manner that in a case where in inlet pipe interior of the engine is partitioned by a rectifying plate into upper and lower flow paths, a flow velocity at a center of the flow path on an upper side, and at a center of the flow path on a lower side is increased. Consequently, a flow velocity distribution of air in a cylinder diametrical direction of a valve head of an inlet valve becomes a peak value on both sides of the valve head center. Therefore, by impinging most of the injected fuel spray upon both sides of the center of the valve head, vaporization of the fuel spray can be performed with good efficiency.
