在内燃机一般性能试验中,进气平均流量并不是一项必测项目;但在内燃机设计试制及研究改进过程的某些专项试验中,却往往需要测定进气平均流量。因此,在内燃机的测试技术中,进气平均流量的测量虽然不能算作最基本的测试技术,但可属一种重要的测试
In the general performance test of the internal combustion engine, the average intake air flow rate is not a necessary test item; however, in some special tests of the trial design and improvement process of internal combustion engines, it is often necessary to determine the average intake air flow rate. Therefore, in the internal combustion engine testing technology, although the average intake flow measurement can not be counted as the most basic test technology, but it can be an important test
