摘要：
An engine includes: an intake port that includes a main flow passage that communicates with a combustion chamber via a throat section; the main flow passage section includes a first/second surfaces; a first extended line defined by extending an end of the first surface toward the combustion chamber is located at the throat section side rather than an umbrella section of an intake valve when the intake valve is in a maximum lift state; a crossing position between the end of the first surface and the throat section has a bent shape; a second extended line defined by extending a middle line located at the middle of the first surface and the second surface toward the combustion chamber is located at the combustion chamber side rather than a portion of a valve seat that is closest to the exhaust port.
摘要（中）：
发动机包括：进气口，其包括经由喉部与燃烧室连通的主流道; 主流道部分包括第一/第二表面; 当所述进气门处于最大升程状态时，通过将所述第一表面的端部朝向所述燃烧室延伸而限定的第一延长线位于比进气门的伞形部分更靠喉部侧处; 第一表面的端部与喉部之间的交叉位置具有弯曲的形状; 通过将位于第一表面和第二表面中间的中间线朝向燃烧室延伸而限定的第二延长线位于燃烧室侧而不是最靠近排气口的阀座的一部分。
