带箭头的虚线代表空气流向，而带箭头的实线代表冷却液流向。 (1) 空气滤清器 (2) 发动机 (3) 涡轮增压器压气机 (4) 后冷器 (5) 涡轮增压器涡轮机 (6) 水泵 (7) 散热器 | |
新鲜空气通过空气滤清器 (1) 吸入涡轮增压器压气机 (3) 中。 空气得到压缩，并且空气由于压缩而变热。 压缩空气流过后冷器 (4)，压缩空气在此被流过的水套水冷却。 经过冷却和压缩的空气密度变大，从而使发动机 (2) 能够燃烧更多的燃油，因此可提供更大的功率。 发动机的排气流过涡轮增压器涡轮机 (5)，为驱动涡轮增压器压气机提供能量。
在水套水冷却系统内，冷却液流量被分流。 水泵 (6) 强制部分冷却液流过发动机冷却液通道。 冷却液循环通过发动机，从而完成发动机与冷却液间的换热。 其余冷却液流过后冷器，冷却液在此与经过加热和压缩的空气完成换热。 来自发动机和后冷器的冷却液汇合流过散热器 (7)。 来自风扇的空气吹过散热器，已冷却冷却液。 冷却液通过水泵抽回。
