An intake valve for a combustion engine is described. The intake valve has a head portion that is designed to improve the flow of air-fuel mixture around the head portion and into the combustion chamber. The head portion has a beveled or rounded edge at the top surface. The angle changes from the underside surface to the top surface are rounded to prevent separation of the air-fuel mixture from the surface of the intake valve. In addition, the underside surface of the head portion has a plurality of helical grooves that induce a circular flow to improve mixing of the air-fuel mixture in the chamber. The helical grooves also improve heat exchange between the air-fuel mixture and the intake valve. 本申请介绍了种内燃机进气门。进气门设有头部，头部设计成用于改善围绕头部和进入燃烧室的空气燃料混合物的流动。头部在顶部表面设有斜面边缘或弧形边缘。从底部表面至顶部表面之间角度变化呈弧形，以防止空气燃料混合物从进气门的表面分离。另外，头部的底部表面设有多个螺旋槽，螺旋槽引导环形流动以改善燃烧室内空气燃料混合物的混合。螺旋槽还改善了空气燃料混合物和进气门之间的热交换。
