| 摘 要： | 均质充量压缩燃烧(HCCI)技术由于其较高的燃油经济性和极低的NOx及PM排放越来越受到重视,但是由于HCCI模式发动机运行区域狭小,限制了其在实际中的应用。对限制HCCI发动机运行区域的因素进行了分析,并研究讨论了拓宽HCCI模式运行区域的方法,包括使用进气增压、提高压缩比、使用混合燃料和废气再循环(EGR)等,能在一定程度上拓宽HCCI发动机在高负荷或低负荷时的运行区域,使HCCI燃烧技术能在发动机高负荷和低负荷的工况下适用。

| Abstract: | The homogeneous charge compression ignition(HCCI) has obtained more and more regards because of its higher efficiency and extremely low emissions of NOx and particulate matter(PM) at part load.However,HCCI engine could not be employed widely because of its limited operating range.The constraints and the approaches to expanding the operating range of HCCI engine are discussed in the paper,including the turbocharge,the increase of compression ratio,the use of mixed fuel,etc.These measures expand the operating range of HCCI engine to a certain extent,and make the HCCI combustion technology employed in high-load and low-load working conditions of engine. |
