摘要： An underhood air flow management system for a truck which includes cowl openings defined between cowl extensions and the rear edges of depending hood sections. Most preferably the cowl extension extends forwardly and inwardly toward the longitudinal centerline of the truck. The cowl extensions assist in deflecting air to the cowl openings, the air having passed through a radiator, along the sides of an engine and engine compartment, and through the cowl openings. The cowl openings preferably extend the full height of the depending hood sections. The bumper of the truck includes a lower extension. In addition, the front wheel wells of the truck are sealed at the front, partially sealed at the side and may be sealed at their rear to reduce the escape of air from the engine compartment through the front wheel wells. The cowl openings are preferably door-free and also lack air flow hindering severe transitions. A charge air cooler may be positioned ahead of the radiator and a fan may be positioned between the radiator and engine. Preferably the radiator is provided with seals so that air cannot enter the engine compartment without passing through the radiator. Seals may be provided between the charge air cooler and the radiator.
摘要翻译：一种用于卡车的底座气流管理系统，其包括在前围罩延伸部和后排罩部分的后边缘之间限定的前罩开口。最优选地，整流罩延伸部朝着卡车的纵向中心线向前和向内延伸。整流罩延伸件有助于将空气偏转到前罩开口，空气已经沿着发动机和发动机舱的侧面通过散热器，并且通过整流罩开口。整流罩开口优选地延伸排气罩部分的整个高度。卡车的保险杠包括一个较低的延伸部分。另外，卡车的前轮油井在前部密封，部分地密封在侧面，并且可以在其后部被密封，以减少来自发动机舱的空气通过前轮井的逸出。整流罩开口优选是无门的，并且还缺少妨碍严重过渡的气流。增压空气冷却器可以位于散热器之前，并且风扇可以位于散热器和发动机之间。优选地，散热器设置有密封件，使得空气不能通过散热器而不能进入发动机室。可以在增压空气冷却器和散热器之间设置密封。
