第一章 进气系统
Chart 1 Intake System
1. 空气滤清器应满足发动机要求（表 1）。
The air filter should satisfy the engine requirement (Table 1).
表1 Table 1
2. 空气滤清器安装在合适的位置，并带有空气滤网。
The air filter must be mounted in a reasonable location and air screen is needed.
3. 进气管路尽量短并不能有锐角弯曲。压气机进气阻力小于 5kPa，压气机出口
至混合器最大压降 13.6kPa。
The air intake piping is as short as possible and sharp curves are avoided. The
resistance before the compressor should be less than 5kPa, and the air pressure
drop between the compressor outlet and the mixer cannot be more than 13.6kPa.
4. 空气进气管路的材料不会生锈。
The material of the air intake piping is free from rust.
5. 空气进气管路连接可靠、没有泄漏。
The air intake piping is connected reliably without any leakage.
6. 与中冷器连接的管路尺寸（表 2,图1）。
The size of the piping connected to the intercooler (Table 2, Figure 1)
