Experiments conducted with moderate compression ratios (10.4 and 15) and using two modes of HCCI control, i. e. intake heating and NVO (NegativeValve Overlap) received the expected results.
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:活塞自左向右移动时,泵缸内形成负压,则贮槽内液体经吸入阀进入泵缸内。

How it works: the piston moves from left to right, form a negative pressure pump cylinder, then the suction tank fluid through the valve into the pump cylinder.
