1.進汽門早開,排汽門晚關所以部份未燃燒完全的殘餘油氣會在排氣行程時被擠回進氣崎管,久了就會形成積碳油垢。
2.清積碳前空氣流量計感測到的空氣進氣量因為堵塞所以較少(同樣開度下),清完後同樣開度下進氣量會跟清洗前不同所以給電腦一段時間修正供油量。
※ 引述《flowsinyou (宅哥)》之銘言:
: 想問一下,為何要清節流閥。
: 聽到很多人都說要清節流閥,但是為什麼?
: (五期噴射)
: 1.
: 節流閥不就只有空濾空氣流進去嗎?那為什麼會髒?為什麼會有積碳?
: 2.
: 為何清完節流閥要怠速學習?(新勁戰)
: 不就只是把裡面的髒東西清掉,空氣流速變更好,為何要怠速學習?
: 那換高流量空濾不就也要怠速學習了?
: 感謝解惑!
