| 摘 要： | 在微粒过滤器的基础上,建立了具有清洁再循环废气的、基于通用排气氧浓度传感器(UEGO)的闭环控制柴油机EGR系统.用UEGO测得的空燃比作为反馈信号进行闭环控制,使EGR系统能充分发挥降低NOx的潜力.

| Abstract: | A new EGR system, which is based on universal exhaust gas oxygen (UEGO) sensor and controlled by a closed loop, is developed. The system uses the filtered clean recirculation exhaust gas. Using the air-fuel ratio measured by UEGO as the feedback to control EGR, the potential of depressing NOx of the EGR system can be brought into play sufficiently. |
