The combustion characteristics of iso-octane/diesel and ethanol/bio-diesel both show a two-stage heat release without HCCI low temperature reactions.

本文首先采用双燃料的方式，对正庚烷/柴油、异辛烷/柴油、乙醇/生物柴油这三种双燃料组合的HCCI/DI分层复合燃烧与排放特性进行深入研究和比较分析。

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。
