通过残余气体捕集实现的均质充量压缩点火（HCCI）燃烧受到低负荷扩展和燃料经济性惩罚的限制，而单独通过进气预热实现的均质充量压缩点火（HCCI）燃烧受到高进气热需求和废热回收的限制。在所提出的研究中，系统的发动机实验进行了单缸发动机上的残余气体捕集和进气预热的组合使用，以实现优化燃烧和更好的燃料转换效率在HCCI操作范围内。研究分析了残余气体捕集与进气预热的不同组合对HCCI燃烧的影响。结果表明，从残余气体捕集到进气预热的过渡对燃油经济性和排放有显著影响。由于气门结构的改变而导致的损失减少对燃油经济性的改善贡献了一半以上。排放的变化既取决于燃烧温度的影响稀释充电和缸内分布的实施形式的影响。研究还表明，当进气温度进一步升高时，增加的效益变得更小。因此，通过将余热回收和残余气体捕集相结合，可以在进气热需求和发动机效率之间实现相对合理的折衷，以优化HCCI燃烧。在HCCI燃烧的典型负荷范围内，与单独采用负气门重叠量方法相比，利用余热回收补充进气预热可提高8-12%的燃油经济性。此外，低负载边界有效地扩展到0.8巴，而不会遭受CO和HC排放的过度增加。
Homogeneous charge compression ignition (HCCI) combustion achieved by residual gas trapping suffers from the limitation of the low load extension and fuel economy penalties whilst achieved by intake preheating alone is limited by the high intake thermal requirement and waste heat recovery. In the presented research, systematic engine experiments were carried out on a single cylinder engine on the combined use of residual gas trapping and intake preheating to achieve optimized combustion and better fuel conversion efficiency in the HCCI operational range. The effect of different combinations between residual gas trapping and intake preheating on HCCI combustion was explored and analyzed. It was indicated that the implementation transition from residual gas trapping to intake preheating significantly influenced the fuel economy and emissions. The decreased loss resulting from changed valve configuration contributed much more than half of the fuel economy improvement. The variation in emissions depended both on the combustion temperature influenced by dilution charge and the in-cylinder distribution affected by implementation form. It was also demonstrated that the increased benefit became less when the intake temperature further went up. Thus a relatively reasonable compromise between intake thermal demand and engine efficiency could be achieved to optimize the HCCI combustion by combining waste heat recovery and residual gas trapping. Compared to negative valve overlap method alone, the supplementary of intake preheating by waste heat recovery provided 8–12% fuel economy improvement throughout the typical load range of HCCI combustion. Also the low load boundary was effectively extended to 0.8 bar, without suffering excessive increase in CO and HC emissions.
