渦(wo)(wo)輪增(zeng)(zeng)壓器實際上是(shi)一種空(kong)(kong)氣(qi)(qi)(qi)壓縮機，通過壓縮空(kong)(kong)氣(qi)(qi)(qi)來(lai)增(zeng)(zeng)加進(jin)氣(qi)(qi)(qi)量。它是(shi)利用發動(dong)(dong)(dong)(dong)(dong)機排出(chu)(chu)的(de)(de)廢(fei)氣(qi)(qi)(qi)慣性沖力(li)來(lai)推動(dong)(dong)(dong)(dong)(dong)渦(wo)(wo)輪室內的(de)(de)渦(wo)(wo)輪，渦(wo)(wo)輪又帶動(dong)(dong)(dong)(dong)(dong)同軸(zhou)的(de)(de)葉(xie)輪，葉(xie)輪壓送(song)由(you)空(kong)(kong)氣(qi)(qi)(qi)濾清(qing)器管道送(song)來(lai)的(de)(de)空(kong)(kong)氣(qi)(qi)(qi)，使之增(zeng)(zeng)壓進(jin)入氣(qi)(qi)(qi)缸。當發動(dong)(dong)(dong)(dong)(dong)機轉速(su)(su)增(zeng)(zeng)大(da)，廢(fei)氣(qi)(qi)(qi)排出(chu)(chu)速(su)(su)度與渦(wo)(wo)輪轉速(su)(su)也同步增(zeng)(zeng)加，葉(xie)輪就壓縮更多的(de)(de)空(kong)(kong)氣(qi)(qi)(qi)進(jin)入氣(qi)(qi)(qi)缸，空(kong)(kong)氣(qi)(qi)(qi)的(de)(de)壓力(li)和(he)密度增(zeng)(zeng)大(da)可以(yi)燃(ran)(ran)燒更多的(de)(de)燃(ran)(ran)料，相應增(zeng)(zeng)加燃(ran)(ran)料量和(he)調整發動(dong)(dong)(dong)(dong)(dong)機的(de)(de)轉速(su)(su)，就可以(yi)增(zeng)(zeng)加發動(dong)(dong)(dong)(dong)(dong)機的(de)(de)輸出(chu)(chu)功率了。
