Working principle: piston moves from left to right, form a negative pressure pump cylinder, the liquid tank into the pump by the inhalation valve cylinder.───工作原理：活塞自左向右移動時，泵缸內形成負壓，則貯槽內液體經吸入閥進入泵缸內。
Experiments conducted with moderate compression ratios (10.4 and 15) and using two modes of HCCI control, i. e. intake heating and NVO (Negative Valve Overlap) received the expected results.───試驗在一個專用于HCCI研究的單缸發動機上實施，采用兩種中等的壓縮比(10.4和15)和兩種HCCI模式(進氣加熱和負氣門疊開)，試驗結果證實了這種期望。
Control of HCCI combustion in a two-cylinder GDI engine with negative valve overlap───負閥重疊的雙缸直噴汽油機HCCI燃燒控制
HCCI Combustion Based on Gasoline Split Direct Injection with Negative Valve Overlap───基于缸內分段直噴和負氣門重疊角汽油機的HCCI燃燒
Large negative valve timing interval would be beneficial to the improvement of combustion stability under low load whereas and small valve interval was favorable to the stability under high load.
