摘要：
PROBLEM TO BE SOLVED: To solve a problem in a conventional intake device wherein control is performed upstream of an intake valve device and fuel spray sticking to the wall surface is not sufficiently prevented, and furthermore a low system cost, the atomization of fuel and short-time conveyance are required for the improvement of performance.
SOLUTION: Intake air flowing in from the intake valve device is supplied to be large in quantity (high in speed) to the ignition device side of an internal combustion engine, and flat fuel spray injected from a fuel injection valve is locally injected to the ignition device side of a shade of the intake valve device and led as a tumble flow to the ignition device while vaporization mixing is accelerated in a combustion chamber, to realize stable combustion. By the operation of a skirt for regulating an intake air flow, an intake passage formed of an intake valve and a valve seat is formed large on the side close to the ignition device and small on the side far from the ignition device, i.e., the cylinder side, and the intake flow locally with large flow is fed into the combustion chamber to effectively form tumbles.

要解决的问题为了解决在进气阀装置的上游进行控制的传统进气装置的问题，并且不能充分防止粘附在壁面上的燃料喷雾，此外，系统成本低，雾化 燃油和短时间运输是提高性能所必需的。
解决方案：从进气阀装置流入的进气量被供给到内燃机的点火装置侧的量（高速），并且从燃料喷射阀喷射的平坦的燃料喷雾被局部注入 到达进气阀装置的灯罩的点火装置侧，并且在燃烧室中加速汽化混合的同时引导到点火装置的滚筒流动，以实现稳定的燃烧。 通过用于调节进气流量的裙部的操作，由进气阀和阀座形成的进气通道在靠近点火装置的一侧形成较大，并且在远离点火装置的一侧形成较小，即， 气缸侧，局部流动大的进气流进入燃烧室，有效地形成滚筒。 版权所有（C）2004，JPO＆NCIPI
