Asenginepowerandcombustionpressureareincreased,thepressureontheoilintheupperchamberisalsoincreased.Whenthispressureexceedsthesettingofthespring-loadeddischargevalve,asmallamountofoilpassestothecrankcase,andtheouterpistonmovesdownward.Thismovementresultsinanincreaseinclearancevolumebetweentheouterpistonandthecylindercombustiondome,Whichreducesthecompressionratio.Thisprocesscontinuesuntiltheupperpistoncontactstheinnerpiston,preventinganyfurtherreductioninthecompressionratio.
何耀喜回答:
当发动机功率和燃烧压力增加时,上部腔室中的油压也会增加.当该压力超过弹簧负载排出阀的设定值时,少量油就会传递到曲轴箱,外活塞就向下移动.这种运动会导致外活塞和气缸燃烧圆顶之间的间隙容积增加,压缩比降低.该过程会持续,直到上活塞接触到内活塞时才会停止,以阻止压缩比进一步的降低.
