EGR对双燃料发动机排放特性的影响

Influences of EGR on Emission of Dual Fuel Engine

废气再循环技术是降低发动机有害排放的有效手段之一。本文介绍了应用于双燃料发动机的废气再循环的装里和实验方法，并详细分析了废气再循环对发动机排放的影响。实验证明朱用废气循环技术降低了发动机的有害排放物。

EGR method is one the effective technologies to reduce the poisonous emissions of en- gine. This paper introduces the equipment and experiment methods of EGR, and analyses the experimental results of dual-fuel engine with EGR. The results show that EGR can dramatically reduce the poisonous emissions of dual-fuel engine.
