: 推 zechsiw:內洩會把多餘的氣丟回渦輪 保持渦輪轉動 滯待較少 05/01 03:39
: → zechsiw:外洩的話 渦輪只能靠引擎排氣去推動 樓下的應該是這樣吧? 05/01 03:43
: → DYE:以兩公斤的壓力為例好了 引擎打到這樣已經是很高增壓了 05/01 08:13
: → DYE:這樣的壓力卻很難推動氣動工具 05/01 08:16
: → DYE:我的意思是卸壓的氣流推動渦輪葉片的效果有限 05/01 08:16
: → DYE:內循環的氣流出口幾乎是開放空間 也不是對著葉片作工 05/01 08:17
: → DYE:內循環最大的優點 就是讓連通渦輪進氣與出氣側成一個封閉循環 05/01 08:18
: → DYE:這樣在回油的時候 經過流量計的空氣量等同引擎的進氣量 05/01 08:20
: → DYE:這樣電腦接受的流量信號還是很準確的 05/01 08:22
: → DYE:如果是外放式 回油的瞬間的空氣是從流量計->渦輪->卸壓閥-大氣 05/01 08:22
: → DYE:這樣經過流量計的空氣量大於引擎的進氣量 電腦會誤判多噴油 05/01 08:24
: → DYE:某些例子里 回油卸壓就會熄火 05/01 08:25
: → DYE:當然有些是用map的形式 這就無所謂 05/01 08:31
正常工作時的空氣氣流方向
空濾器 -> 流量計 -> 渦輪 -> 洩壓閥 -> 節氣門 -> 引擎
內循環洩壓時
空濾器 -> 流量計 -> 渦輪 -> 洩壓閥 -> 節氣門 -> 引擎
\ /
<---------
雖然洩壓閥出口是在渦輪前 但是渦輪前的位置幾乎可以說是通大氣
所以洩壓閥出來的氣流很難對葉片作功
內循環 低油門開度時
空濾器 -> 流量計 -> 渦輪 -> 洩壓閥 -> 節氣門 -> 引擎
\ /
---------->
低油門開度時 進氣減少渦輪的阻礙
外洩式
空濾器 -> 流量計 -> 渦輪 -> 洩壓閥 -> 節氣門 -> 引擎
\
---> 大氣
用MAP的引擎沒有流量計 內循環或是外洩無所謂
所以某些競賽用的車就直接外洩
