概述了世界各国涡轮增压柴油机运用废气再循环 (EGR)技术降低排放的发展状况 ,介绍并比较了内部EGR系统、在进排气管装有节流阀的EGR系统、对废气加压的EGR系统、装文曲利管的EGR系统、利用进排气管的压力波动的EGR系统以及有变截面涡轮等典型的废气再循环系统。指出应针对不同的排放法规采取相应的EGR措施。
The development of turbocharged diesel engines using exhaust gas recirculation (EGR) technology in various countries around the world is summarized. The internal EGR system is introduced and compared with the EGR system with throttles in the exhaust pipe. The EGR System, an EGR system with a venturi, an EGR system utilizing pressure fluctuation of the intake and exhaust lines, and a typical exhaust gas recirculation system with a variable section turbine. It is pointed out that corresponding EGR measures should be taken for different emission regulations.
