增压器用管总成

1、发动机增压器进/回油管：给涡轮增压器导入/出循环润滑油。要求承受较高的工作温度并对清洁订有较高要求。

2、发动机增压器进/回水管：给涡轮增压器导入/出循环冷却液，保证涡轮增压器正常运作。要求在环境温度较高条件下正常工作。

3、发动机EGR管：排气歧管中的废气经EGR阀适量导入进气歧管并重新燃烧的管路，以减少NO化合物的排放。一般由不锈钢管构成，能承受较高的工作温度。要求有精密的制作尺寸。

4、发动机AKF管：燃油蒸气管路。燃油蒸气回收到进气歧管的管路，避免燃油油中的燃油蒸气直接排放到空气中。一般由不锈风管构成，对清洁度有较高要求。

Supercharge Cooling ASM

1. Engine supercharger oil feed / return pipe: Feed / Return oil lubrication for turbocharger. It requires to withstand higher operating temperature and maintain higher cleanness level.

2. Engine supercharger coolant feed / return pipe: Feed / Return coolant circulation for turbocharger. It requires to run at a higher working temperature.

3. Engine EGR pipe: Exhaust-gas recirculation pipe which leads the engine exhaust gas from exhaust manifold into the inlet manifold through EGR valve and re-combustion. It is used to reduce the NOx of the exhaust gas. In general speaking. EGR pipe is made from stainless steel, requires precise dimensions and operating at high temperature.

4. Engine AKF pipe: Fuel vapour pipe. Fule vapour is recycled to the inlet manifold to avoid it directly into the air. This pipe is normally made from stainless steel and requires high cleanness level.
