均质充量压缩点火（HCCI）燃烧是一种同时降低内燃机NOx和碳烟排放的燃烧概念。考虑到日益严格的柴油机排放限制，研究工作已经投入到HCCI燃烧中作为常规柴油机燃烧的替代方案。本文综述了在直喷式柴油机上采用提前喷射、多次喷射和延迟喷射实现均质压燃燃烧的方法。本文综述了影响均质压燃（HCCI）运行的主要因素，如喷油器特性、喷油压力、活塞几何形状、压缩比、进气温度、废气再循环（EGR）和增压或涡轮增压等。研究了设计和运行参数对HCCI柴油机排放的影响，特别是NOx和碳烟。对于这些参数中的每一个，理论进行了讨论，在专业文献中报告的研究比较评价。
Homogeneous Charge Compression Ignition (HCCI) combustion is a combustion concept which offers simultaneous reductions in both NOxand soot emissions from internal combustion engines. In light of increasingly stringent diesel emissions limits, research efforts have been invested into HCCI combustion as an alternative to conventional diesel combustion. This paper reviews the implementation of HCCI combustion in direct injection diesel engines using early, multiple and late injection strategies. Governing factors in HCCI operations such as injector characteristics, injection pressure, piston bowl geometry, compression ratio, intake charge temperature, exhaust gas recirculation (EGR) and supercharging or turbocharging are discussed in this review. The effects of design and operating parameters on HCCI diesel emissions, particularly NOxand soot, are also investigated. For each of these parameters, the theories are discussed in conjunction with comparative evaluation of studies reported in the specialised literature.
