通过对循环工质容积进行控制,可以使循环逼近定压加热,并可自动调节压缩比,为改善高增压柴油机性能提供了途径.本文分析了传动机构中弹簧容积控制装置对柴油机工作循环的影响,并给出了初步的实验结果. By controlling the volume of circulating working fluid, it can make the cycle approach to constant pressure heating and automatically adjust the compression ratio to provide a way to improve the performance of high-pressured diesel engine.This paper analyzes the effect of spring volume control device on the working cycle of diesel engine Influence, and gives the preliminary experimental results.
