摘 要：
非道路机械设计匹配发动机进气系统时,进气标定流量、进气阻力限值、滤清效率、进气温度4项主要参数与发动机性能有很大关系;进气流量不足,导致功率下降同时发热量增加;进气阻力限值大,将引起燃油经济性变差,排烟过大,功率降低等问题;滤清效率低,空气中大量杂质进入气缸,将引起缸体严重磨损,缩短使用寿命;进气温度高低,与功率发挥和运转平稳性有很大关系。故进气系统优化设计非常关键。

摘 要：
The four main parameters including air intake rated flow,air intake resistance limit,filtering efficiency and air intake temperature are closely related to the engine performance on matching the intake system of diesel engine in nonroad machinery design. Insufficient inlet flow will lead to the power falling down while the calorific value increases; large air intake resistance limit will cause deterioration of fuel economy,too large smoke removal,bad emission and power coastdown,etc. If the filtering efficiency is low,the cylinder will be worn seriously and the working life will be cut down with a lot of impurities in the air intake flow,and intake temperature has a lot to do with the output power and operation stability.Therefore,the optimization design of intake system is very important.
