在发动机后端安装了四个涡轮增压器 (1) 。 每一个涡轮增压器的涡轮机侧进口都与该涡轮增压器相应的排气歧管相连接。 每一个涡轮增压器的压缩机侧出口都连接在进气管的管道上。

排气流入涡轮机壳体的排气进口。 排气继而推动涡轮机叶轮 (8) 的叶片。
来自空气滤清器的清洁空气由于压缩机叶轮 (4) 的旋转作用被吸入压缩机壳体的进气口。 压缩机叶轮叶片压缩进气。 压缩可使发动机发出更大功率，这是因为压缩使得发动机能够以更高的效率燃烧更多的燃油。
涡轮增压器的最大转速受控于发动机输油量的电子控制。 发动机运转时所处的海拔高度也将控制涡轮增压器的最大转速。
涡轮增压器中的轴承 (5) 和轴承 (7) 使用发动机机油进行压力润滑。 机油经由进油管被输送到上部的进油口 (6) 。 机油继而经由中段内的油道润滑轴承。 机油从底部的出油口 (9) 流出。 机油随后通过涡轮增压器支架中的机油排放口 (3) 返回到飞轮壳体。
