In this system , fuel is injected in negative valve overlap ( NVO ) and the high-temperature residual gas benefits the fuel vaporization .
该系统通过在负气门重叠期进行燃油喷射并利用残余高温废气热氛围促进燃油蒸发实现均质混合气的制备，通过外部冷却EGR实现燃烧相位和速率的控制。

Experiments conducted with moderate compression ratios ( 10.4 and15 ) and using two modes of HCCI control , i.e.intake heating and NVO ( Negative Valve Overlap ) received the expected results .
试验在一个专用于HCCI研究的单缸发动机上实施，采用两种中等的压缩比（10.4和15）和两种HCCI模式（进气加热和负气门叠开），试验结果证实了这种期望。

Fasting triglyceride , fasting free fatty acid , mean free fatty acid within 0 ~ 2 hours in VO were all higher than those in NVO ( P < 0.05 ~ 0.01 ) .
VO亚组的空腹三酰甘油、空腹游离脂肪酸、0～2h平均游离脂肪酸水平均显著高于NVO亚组（P值均<0.05）。
