4、是安裝在發(fā)動機排氣管道上地一臺精致地空氣壓縮機,利用發(fā)動機排出地廢氣推動渦輪室內地渦輪旋轉,渦輪又帶動同軸地葉輪旋轉,這樣,葉輪就把從空氣濾清器進來地空氣進行壓縮,使之增壓進入汽缸.由于進入氣缸地空氣密度增大,可使更多地燃油充分燃燒,因而大大提高了發(fā)動機地功率,降低了燃油消耗. 由于該系統(tǒng)是利用發(fā)動機排出地廢氣驅動渦輪,所以渦輪增壓器經常在高速、高溫下工作,渦輪端地溫度在600度以上,增壓器也以每分鐘8萬-10萬轉地速度高速旋轉.所以為了保證增壓器地正常工作,就要正確使用和維護保養(yǎng)渦輪增壓器.在使用地過程中應注意以下事項.DXDiTa9E3dWhat is the turbocharger?
