純粹好奇想問問
以前還有機械增壓的車款,有時候路上還會看到有kompressor銘牌的MB
或是有一些雙增壓車款(機械增壓+渦輪增壓)
機械增壓和渦輪增壓都是透過強制進氣,讓引擎吸更多空氣,進而提升動力
只是機械增壓是靠曲軸轉動時的扭力去帶動,而渦輪增壓是靠廢氣推動
機械增壓相對於渦輪增壓有幾個優點和缺點:
1.動力輸出的順暢性和NA接近,不像渦輪有turbo lag(雖然現在的小渦輪也很線性了)
2.改裝難度比渦輪要低
3.需要損耗部分引擎動力來驅動增壓器,故高轉速時的表現不如渦輪增壓
4.引擎噪音較大會喵喵喵叫
那麼為什麼機械增壓不若渦輪增壓一樣成為主流?
機械增壓應該也可以和渦輪增壓一樣,縮小引擎排氣量以便符合愈趨嚴格的環保法規吧
雖然現在也有純機增的新款車,或是雙增壓系統的車款
但是機增的普及度好像就是沒渦輪高
