機(jī)濾作用是對(duì)來(lái)自油底殼的機(jī)油中有害雜質(zhì)進(jìn)行濾除,把潔凈的機(jī)油供給曲軸、連桿、凸輪軸、活塞環(huán)等運(yùn)動(dòng)副,起到潤(rùn)滑、冷卻、清洗作用,延長(zhǎng)零部件的壽命。濾清器經(jīng)過(guò)長(zhǎng)時(shí)間使用后其過(guò)濾效能會(huì)下降,通過(guò)過(guò)濾器的機(jī)油壓力會(huì)大大降低。油壓降低到一定程度,機(jī)濾旁通閥會(huì)打開(kāi),未經(jīng)過(guò)濾機(jī)油會(huì)通過(guò)旁路進(jìn)入油路,攜帶雜質(zhì)的會(huì)增加機(jī)件磨損,嚴(yán)重時(shí),甚至?xí)氯偷溃斐蓹C(jī)械故障。所以機(jī)濾一定要定期更換。
