By timely and spatially controlling the physical and chemical characteristics of the fuel at both port injection stage and in-cylinder direct injection stage, HCCI/DI stratified compound combustion is developed to combine the advantages of HCCI and conventional DICI on cycle-to-cycle basis and achieve clean and efficient combustion at full load ranges without misfiring and knocking.Firstly, three types of dual fuel including n-heptane/diesel, iso-octane/diesel and ethanol/bio-diesel a...更多re utilized to investigate the combustion and emission characteristics of HCCI/DI stratified compound combustion. The experimental results indicate that n-heptane/diesel HCCI/DI combustion presents a three-stage heat release consisting of HCCI low temperature heat release, high temperature heat release and diesel diffusive combustion.

本文提出的基于燃料设计与管理的HCCI/DI分层复合燃烧是一种将HCCI燃烧和传统缸内直喷压燃融为一体的新型燃烧方式，通过对燃料理化特性的设计和在预喷与直喷阶段从时间尺度和空间尺度上对均质和非均质混合气制备过程的控制和管理，在发动机的一个工作循环中将均质混合气的HCCI燃烧和非均质混合气的DICI扩散燃烧相融合，彻底消除了HCCI燃烧在小负荷失火和大负荷爆震的弊病，实现了发动机全负荷范围内的高效清洁燃烧。

Experiments were carried out on a HCCI platform to evaluate the effects of cetane number and octane number on the HCCI combustion characteristics and emissions using n-heptane, RON25, RON50, RON75, RON90, and iso-octane.

进一步在发动机上对正庚烷、RON25、RON50、RON75、RON90和异辛烷在不同负荷下的HCCI燃烧特性和排放特性进行了试验研究。

In addition, the HC and CO emissions are much lower than the emissions of HCCI and the indicated thermal efficiency of HCCI/DI is higher than the prototype diesel engine.Furthermore, without spark ignition and hot EGR, the HCCI/DI combustion of in-cylinder directly injected iso-octane is achieved with the induction of thermal and chemical active atmosphere generated by the HCCI combustion of port injected n-heptane.

通过对燃料理化特性、预混合率和缸内直喷时刻这三个影响因素的优化，实现了对HCCI/DI燃烧相位、放热分布和形态的调制，使发动机的负荷拓展到全负荷，在全负荷范围内NOx排放低于40×10-6排放水平，HC和CO排放显著低于HCCI燃烧，同时发动机指示热效率η_i高于原机柴油直喷的水平。
