標題: 第三次試車後. 新仔一問.
各師兄. 我架RTR 第三次放啦...不過有以下問題.

我的是 12級engine , 16%fuel , cool/medium glow plug , s3003 servo , 前set了小小toe out.後toe in.避震中硬(RTR setting,沒有改)
在最快的top speed 時. engine 聲會有點點"繼開"而唔係一氣過,架車有小小搖晃(我沒有裝shell,可能沒有定風).當把油針set rich 小小令top speed 降低,就ok,

1.我的engine是否已損壞了? 是否因為run in 不足.?

2.係咪個 engine 0既極限為後者? (我沒有計埋"死氣喉"的影響,因為不知怎影響).

3.我係咪不要再開至那個"top speed"

4.同16% fuel又有冇關係呢?

5.咁arm有個師兄行過. 提出話"會唔會係被油蓋熄左個火嘴呀?" ,有冇依個可能呢?

thanks r. 又要煩到師兄幫幫手

engine 聲會有點點"繼開" =your 油針 is too lean

咁.係咪話個engine 0既"top speed "係set 到"唔斷" =依個 engine 0既極限.?

nobody will try to find the limit of the engine from lean setting as starting point

Normally, they will set the engine running in rich setting at the beginning....2nd, lean the engine and see its response....continue to lean and monitor the response, if u find that the engine has no more difference in performance, then this is the limit

But, this method only apply for those extreme racers. They no need to consider the life of the engine....the purpose is to squeece the top power within one race...

recommend u lean the engine and monitor the engine, keep it below 110 degree....

agree..

所以都係買個溫度計穩陣d.....

熟咗就開始聽埋engine聲音.....感覺下架車個速度等等...

You pointed out that I should not turn it too lean at the begining. I should slow down my engine to save area to keep working life.

thanks Chris so much . hope its not been too late la.

u ar welcome

作者: pskyng 時間: 2007-11-14 17:00
仲有樣野係. 我start 車後有怠速沒有死火,低高速也ok, 但當行幾轉後若停下來, 個engine 反而沉聲及會死火. 點解呢?

作者: chrishkyung 時間: 2007-11-14 17:04
apart from the engine setting, I know there are various viewpoints in after-run maintenance...

Before adding after-run oils, some people will burn all fuel inside the engine chamber completely.....Personally, I dont recommend this method.....without sufficient lubicrant, the dry running is very harmful to the engine....

For maintenance, I prefer to add excessive after-run oil into the engine....of course, some people will say it is harmful to the chicken leg wooh.....but before u restarting the engine, u can unscrew the plug and rotate the engine to withdraw the after-run oil

good luck...there are plenty of knowledge in these simple two stroke model engines

唔係架..如果倒晒d油先再start....一兩秒就燒晒d油架啦....engine 仲warm 果時做, 唔好太熱果時做...轉數唔會高的, 我諗唔會傷機掛

....OS 說明書都係咁教的... 因為如果仲有油係機裡面, 事後油可能中和唔晒d油....有機會氧化....

試吓打開尾蓋睇下, 你會見倒如果唔燒咗佢, 會淨番一淡油係engine裡面.

不過各施各法...我d friend 玩得密.....after-run 都唔駛落

唔知遲d rc fuel 會唔會好似加德士咁加techron, "清潔引擎"呢

我都有用after run oil, chris 的方法看來很合理. 我下次試下. thanks r.

可以温下先,唔好急,其實已開了高速都唔駛驚,應該可解決問題

玩果時請盡量燒晒d油,玩到熄機,咁就唔會太多油係機裡面.
大油過頭,俾油就自己熄,條PIPE係唔係有油流出嚟???
