engine一問

想問我副偈每次行到半缸油就死火,點解?但如果我一換新火咀又無問題,但我枝火咀壽命每次只可以維持四五缸油,根住又係咁! (因為我別一副os枝火咀可以行到幾升油都無問題!

可能雞肶夠期,試下抬計check下"格冷"同雞肶多唔多虛位

我都想知點解？

會唔會溫度過高？

上面兩位brother都講咗兩点,我都補充會唔會engine壓力過大睇吓要唔要加燃燒室墊片。

但如果你話有虛位,點解我一換新火咀又無事?

一定吾會溫度過高!因為我副偈正常工作溫度係100以上,但我只係set到around100

咁點様為之壓力過大?因為我係二手偈,我買返黎時都無墊

over temp

咪講左無可能0羅!你有無睇我寫乜架!

每間engine廠商都會建議副机用幾多%油,如果用過高%油就要加xxmm厚介子,唔加番適合厚度...裡面嘅壓縮比會影响過爆！好大機會爆燒火咀！但"格冷"同雞肶多虛位都有可能,只不過換新火咀未必即刻燒啫！打開尾蓋望望

咩叫做無可能...sampras=barrel=stephen=takwah=serpent710=police=police2=andre

In most likely sequence
1) Too much play between the conrod and the crankshaft, you can check this by remove the glowplug when the engine is cold and see how much play you have when the piston reach to the top by turning the flywheel
2) Not enough shimming in the under head this will "eat" glowplug
3) Bad bearing

In fact, the mostly likely case is an old engine running too lean but you have ruled it out. Hope this help.

其實我知你好想幫我,不過我真係吾明你寫乜?(除左第三樣)不過都多謝你先! 不過我就好肯定吾係太黏!

以最高可能性排序:
1)連干與豬仔腳虛位太多-上落都過籠,易死火,易死火嘴
2)缸頂介指墊不夠,壓縮比太大,易死火嘴
3)死bearing, 易死火

其實你情況最有可能是舊計過熱,不過你已經排除這個可能性,
p.s.因我不會打繁體,請見諒.這個回答是我老婆幫我

好多謝你同你老婆!!!
