此段譯為：

潤滑系統(tǒng)的功用是潤滑發(fā)動(dòng)機(jī)各零部件的摩擦表面，以減少各零部件摩擦表面的摩擦與磨損，帶走表面熱量，也帶走零件磨損留下的磨屑，提高氣缸的密封性。

功能

發(fā)動(dòng)機(jī)工作過程中運(yùn)動(dòng)部件之間保持良好的潤滑及其重要，潤滑系統(tǒng)（如圖4-1所示）的功用是潤滑發(fā)動(dòng)機(jī)各零部件的摩擦表面，以減少發(fā)動(dòng)機(jī)運(yùn)動(dòng)件之間的摩擦與磨損、帶走表面熱量，也帶走零件磨損留下的磨屑，提高汽缸的密封性。

潤滑系統(tǒng)同時(shí)具有潤滑、散熱、清洗、防腐、密封、減振和液壓作用。參考譯文圖4-1潤滑系統(tǒng)1-油底殼2-機(jī)油集濾器3-機(jī)油泵4
