貌似是这段
The two turbochargers of the eight-cylinder engine are accommodated, along with the catalytic converters, in the V-shaped space between the cylinder banks, which are positioned at a 90-degree angle to one another. This arrangement produces an extremely compact construction and allows model-specific positioning of the intake and exhaust ducts. Their reduced pipe length and larger cross section minimise the pressure losses on the exhaust side of the engine. There is also a smaller distance between the combustion chambers and the catalytic converters, which helps the "cats" reach their optimum operating temperature soon after the engine has started.
------------------------------------------------------
大体意思是说,两个涡轮和三元催化器是在塞在V8发动机的“V”型空间里的,这造就了极其紧凑的布局,并允许进气和排气管能以最优化布置。管道长度的缩短和横截面的增大,使得发动机排气端的压力损失减小到最低。三元催化器和燃烧室的距离也缩短了,使“cats”能更快达到工作温度。
---------------------------------------------------------
所以,外侧管道是进气,里面两条是排气,然后直接通回V8中间的涡轮,是这样吧?
另外cats是啥....这个不知道.... |
