进气系统对493ZQ气波增压柴油机性能的影响

Effect of Inlet System on Performance of 493ZQ Diesel Engine with Pressure Wave Supercharger

在以前的研究工作基础上，为提高发动机的动力性，主要对进气系统进行了改进，并通过气道试验加以验证．性能试验表明：气波增压器的动力性有所提高，达到了预期效果．

Compared with turbocharger, the advantages of pressure wave supercharger (PWS) are most lie in its excellent acceleration and emission performance. Meanwhile after gaining the good acceleration and emission performance, the crucial goal is to improve power performance of PWS. In order to make it, some change on engine inlet system have been adopted. Also an experiment of inlet pipe was made to testify the effect. The research results show that the power performance of PWS diesel engine has been improved satistied..
