摘要： PROBLEM TO BE SOLVED: To provide a gas introduction structure of an intake passage, easily discharging a condensate, the gas introduction structure of the intake passage and an intake manifold, uniformly distributing the gas between cylinders and uniformly diffusing the gas into intake air. SOLUTION: Both sides of bottom faces 10a-16a of emission introduction paths 10-16 are respectively connected to curved wall faces 10b-16b with angles. The condensate water W tends to occur and be concentrated in the angled parts (corners C). Thus, the condensate water W is concentrated on the side of the bottom faces 10a-16a before clogging the emission introduction paths 10-16, and is then easily discharged after moving by the inclination of the emission introduction paths 10-16. Thus, the uniform diffusion of the gas into intake air and the uniform distribution of the gas between cylinders are not hindered. End faces of the emission introduction paths 10-16 are inclined to the opposite direction from the intake flow direction with respect to the connecting end faces of intake branched pipes. Then it rarely causes resistance against the intake flow. According to the inclination, the end faces are hardly exposed strongly to blow-back due to the Atkinson cycle, and the blow-back is rarely guided into the emission introduction paths 10-16. The prevention of deposit adhesion is fully achieved thereby. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：要解决的问题：为了提供进气通道的气体导入结构，容易地排出冷凝物，进气通道的气体导入结构和进气歧管，使气体均匀地分布在气缸之间并均匀地将气体扩散到进气口空气。解决方案：发射引入路径10-16的底面10a-16a的两侧分别以角度连接到弯曲的壁面10b-16b。冷凝水W倾向于发生并集中在角部（角C）中。因此，在堵塞发射引入路径10-16之前，冷凝水W集中在底面10a-16a侧，然后在通过排出物引入路径10-16的倾斜移动之后容易地排出。因此，不会阻碍气体进入空气的均匀扩散和气缸在气缸之间的均匀分布。排气导入路径10-16的端面相对于进气分支管的连接端面与进气流动方向相反的方向倾斜。那么很少会引起抵抗进气的阻力。根据倾斜度，由于阿特金森循环，端面几乎不能很好地暴露于回吹，并且回吹很少被引导到排放物引入路径10-16中。从而完全实现了防止沉积物粘附。版权所有（C）2009，JPO＆INPIT
