Increase the tumble ratio
Improve flow coefficient
本发明公开一种气缸盖、发动机和车辆,包括:主进气道和支进气道;主进气道具有进气端和出气端,进气端与进气歧管连通;支进气道包括第一支进气道和第二支进气道,第一支进气道和第二支进气道均具有进口段、过渡段和出口段,其中,出口段朝向第一方向延伸且朝向远离排气管的方向倾斜,进口段朝向第一方向延伸且朝向远离出口段的倾斜方向的方向倾斜,出口段的倾斜角度小于进口段的倾斜角度。通过对进口段和出口段的延伸方向和倾斜角度进行设计,并保证进口段的倾斜角度大于出口段的倾斜角度,能够有效减少空气在流通过程中的流量损失,使得空气的流通更加顺畅,同时,能够同时提高气缸内的滚流比和气体流量系数。
