STCS在汽車又稱為VTCS- Variable Tumble Control System可變渦流控制
是汽車業為了通過歐洲國家嚴苛的環保法規而研發出來的
功能:在不同的溫度和轉速下將進氣歧管的開度打開不同的開度 以滿足發
動機各個運轉狀態空氣的需求. 原理:在同一運轉狀態下 不同的VTCS閥門
開度,進入發動機的氣流流速發生改變 形成渦旋 渦流即是我們常說的旋渦
發動機的油氣混合達更加充分,特別是發動機在低溫冷起動和發動機處於低負
荷時 混合氣的霧化不好,燃燒不充分,排放不良 為了改善低溫時汽油的霧化水準
低轉時 ECU控制蝶型閥半開 使進氣經過較窄的進氣道產生平行
層狀渦流,增加混合氣的攪拌均勻,提升燃燒效率及扭力
高轉時 蝶型閥處於中間的位置,進氣面積達到最大
產生垂直於活塞的渦流,產生大馬力

舊款的VIP系統,在汽車上又稱為VIS- Variable Intake-air System可變進
氣歧管
功能:在PCM的控制下 在小負荷低轉速到大負荷高轉速範圍內都保持高
的扭矩.
工作原理:改變有效進氣歧管的長度 有效控制進氣氣流在進氣道中的流動
慣性 使氣流的流動壓力波的頻率和進氣門的頻率在不同負荷下適時吻合
進而最大程度保證引擎在任何負荷狀態的進氣量.實質是利用的中慣性諧波
增壓的原理來實現引擎的最大進氣量. 當發動機轉速低於設定轉速時VIS閥門
是關閉的,氣流的路徑較長;當發動機轉速大於設定轉速時 VIS起作用,閥門
打開,使進氣氣流行經較短的進氣岐管。
藉由這種進氣管路中閥門的切換,來使進氣管路改變成長、短二種路徑。以滿
足引擎在高轉速運轉時需要流速快、動能大的氣流;並且在低轉速時供給引擎
適當流量的空氣。這樣就能夠使引擎在高轉速時獲得較大的馬力,而在較低轉
速時有較佳的油耗表現。

HONDA的iVTEC,TOYOTA的VVTi這種才是真正控制氣門正時跟揚程的設計
(可變氣門控制系統)
說到改變進氣門數的話,HONDA 1983年裝在CBR400F NC07E上面的REV系統才算
(也就是現在CB 400的VTEC系統,跟汽車用的VTEC不同)
REV是利用油壓控制,讓6750rpm之前,只讓進排氣門打開一組 變成2V車
6750rpm後 變成二進二出
這是真正在2V跟4V之間轉換的設計,跟STCS還有VIP那種控制進氣渦流還有歧管長度
原理完全不同
