采用涡轮增压器自循环作压气机特性试验,往往因受到涡轮进气温度的限制而得不到广泛采用。本文介绍采用自循环补气,以降低涡轮进口温度,从而作出能满足柴油机配机需要的压气机特性曲线。这在经济上具有一定的实用价值。本文还阐述了影响自循环的某些因素。 The use of turbocharger self-cycle compressor characteristics of the test, often due to the turbine inlet temperature limit and not widely used. This paper describes the use of self-cycle qi, to reduce the turbine inlet temperature, so as to meet the needs of diesel engine with compressor characteristics curve. This has a certain economic value. This article also explains some of the factors that affect self-cycling.
