渦(wo)輪(lun)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)器(qi)實際(ji)上是一種(zhong)空氣壓(ya)(ya)縮(suo)(suo)機(ji)，通過壓(ya)(ya)縮(suo)(suo)空氣來增(zeng)(zeng)(zeng)(zeng)(zeng)加進(jin)氣量。它是利用發動(dong)(dong)(dong)機(ji)排(pai)出(chu)的(de)(de)廢(fei)(fei)氣慣性沖力(li)來推動(dong)(dong)(dong)渦(wo)輪(lun)室內(nei)的(de)(de)渦(wo)輪(lun)，渦(wo)輪(lun)又(you)帶動(dong)(dong)(dong)同(tong)(tong)軸的(de)(de)葉輪(lun)，葉輪(lun)壓(ya)(ya)送(song)由空氣濾清(qing)器(qi)管道(dao)送(song)來的(de)(de)空氣，使之增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)進(jin)入氣缸(gang)。當發動(dong)(dong)(dong)機(ji)轉速增(zeng)(zeng)(zeng)(zeng)(zeng)大(da)，廢(fei)(fei)氣排(pai)出(chu)速度(du)與渦(wo)輪(lun)轉速也(ye)同(tong)(tong)步增(zeng)(zeng)(zeng)(zeng)(zeng)加，葉輪(lun)就壓(ya)(ya)縮(suo)(suo)更(geng)多的(de)(de)空氣進(jin)入氣缸(gang)，空氣的(de)(de)壓(ya)(ya)力(li)和密度(du)增(zeng)(zeng)(zeng)(zeng)(zeng)大(da)可(ke)以燃(ran)(ran)燒(shao)更(geng)多的(de)(de)燃(ran)(ran)料(liao)，相應(ying)增(zeng)(zeng)(zeng)(zeng)(zeng)加燃(ran)(ran)料(liao)量和調(diao)整發動(dong)(dong)(dong)機(ji)的(de)(de)轉速，就可(ke)以增(zeng)(zeng)(zeng)(zeng)(zeng)加發動(dong)(dong)(dong)機(ji)的(de)(de)輸出(chu)功率了(le)。
