、電磁閥等組成。柴油機(jī)噴油系統(tǒng)將燃油霧化，并分布在燃燒室內(nèi)與空氣混合的部件。它主要由噴油嘴和噴油器體組成，它在缸蓋上的安裝位置與角度取決于燃燒室的設(shè)計(jì)。噴油器分為開式和閉式兩種。開式噴油器結(jié)構(gòu)簡(jiǎn)單，但霧化不良，很少被采用。閉式噴油器廣泛應(yīng)用在各種柴油機(jī)上。柴油經(jīng)噴油泵將油壓提高到100MPa以上，通過噴油器噴入氣缸，在很短時(shí)間內(nèi)與壓縮后的高溫空氣混合，形成可燃混合氣。由于柴油機(jī)壓縮比高（一般為16-22），所以壓縮終了時(shí)氣缸內(nèi)空氣壓力可達(dá)3.5-4.5MPa，同時(shí)溫度高達(dá)750-1000K（而汽油機(jī)在此時(shí)的混合氣壓力會(huì)為0.6-1.2MPa，溫度達(dá)600-700K），**超過柴油的自燃溫度。因此柴油在噴入氣缸后，在很短時(shí)間內(nèi)與空氣混合后便立即自行發(fā)火燃燒。氣缸內(nèi)的氣壓急速上升到6-9MPa，溫度也升到2000-2500K。在高壓氣體推動(dòng)下，活塞向下運(yùn)動(dòng)并帶動(dòng)曲軸旋轉(zhuǎn)而作功，廢氣同樣經(jīng)排氣管排入大氣中。河南專業(yè)噴油器銷售電話</p><p
