渦(wo)(wo)(wo)(wo)輪(lun)增(zeng)壓器實際(ji)上是一種(zhong)空氣(qi)(qi)(qi)壓縮(suo)機,通過壓縮(suo)空氣(qi)(qi)(qi)來增(zeng)加(jia)進(jin)氣(qi)(qi)(qi)量。它是利用發(fa)(fa)動(dong)(dong)機排(pai)出(chu)的(de)廢氣(qi)(qi)(qi)慣性沖力(li)來推動(dong)(dong)渦(wo)(wo)(wo)(wo)輪(lun)室(shi)內的(de)渦(wo)(wo)(wo)(wo)輪(lun),渦(wo)(wo)(wo)(wo)輪(lun)又(you)帶動(dong)(dong)同軸的(de)葉輪(lun),葉輪(lun)壓送(song)(song)由空氣(qi)(qi)(qi)濾(lv)清器管道送(song)(song)來的(de)空氣(qi)(qi)(qi),使之(zhi)增(zeng)壓進(jin)入(ru)氣(qi)(qi)(qi)缸。當發(fa)(fa)動(dong)(dong)機轉速增(zeng)大(da),廢氣(qi)(qi)(qi)排(pai)出(chu)速度(du)與渦(wo)(wo)(wo)(wo)輪(lun)轉速也同步增(zeng)加(jia),葉輪(lun)就(jiu)壓縮(suo)更(geng)多的(de)空氣(qi)(qi)(qi)進(jin)入(ru)氣(qi)(qi)(qi)缸,空氣(qi)(qi)(qi)的(de)壓力(li)和密度(du)增(zeng)大(da)可(ke)以(yi)燃(ran)燒更(geng)多的(de)燃(ran)料,相應增(zeng)加(jia)燃(ran)料量和調整發(fa)(fa)動(dong)(dong)機的(de)轉速,就(jiu)可(ke)以(yi)增(zeng)加(jia)發(fa)(fa)動(dong)(dong)機的(de)輸(shu)出(chu)功率(lv)了(le)。
