排入 D 檔車子當然...(恕刪)
會不會是你的冷車轉速比較高一點, 將冷車轉速和當時車外溫度紀錄下來,
這樣才有辦法判斷正不正常,或許怠速馬達不正常

各位說的等個幾秒 , 正是我現在應對的方式
我們都是太聰明,太有"知識" 的台灣車主,
但這是個" 安全" 問題,
在台灣通常出事,反正都算是駕駛人習慣不良問題, 車都正常.
其實在其他國家可就沒那麼好過關了
請翻開應該平常不會看的車主手冊, page 113
寫到
"立即起步, 切勿於車輛靜止時暖引擎, 而應以適當的引擎轉速立即起步"
BMW 北美版的使用手冊 原文
Drive away without delay
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.
This is the fastest way for the cold engine to
reach its operating temperature.
"Drive away without delay", "Do not wait" ,"立即起步, 切勿 "
vs "moderate engine speeds"
呵, 一千五百轉不到, 算不算 moderate/ 適當 speed ?
底下一段, 也是列在 bmw北美版的使用手冊前言, 有興趣的花時間參考一下
就知道老美買車比我們便宜,但對行車安全問題的規定的重視, 嚴肅多了,
我沒有像老美有NHTSA可通報, 所以上Mobile 01 通報一下囉….

請注意, 是 "適當的轉速" 起步,
所以本就應該待轉速正常後再起步,
所謂的Warm Up, 是指達到擎工作溫度, 而與轉速不相關,
所謂的不須"Warm up", 是指不須等待引擎達到工作溫度,
現在的引擎都是電腦控制噴射供油, 非化油器引擎, 本就應該在正常的引擎轉速下立即起步,
不須要等待引擎達到工作溫度再起步,
其他的車子我不知道, 但是以我的車子而言(E71 xDrive50i), 1500轉真的不是起步的適當轉速,
E71 xDrive50i在引擎1500轉的時候, 渦輪是處於起動狀態, 本來就不是應該起步的轉速,
正常起步轉速應該在1,000轉或以下,
以我開過的BMW(E46 330i, E90 330i, E71 50i)冷車發動, 會在10秒內回到1000轉以下, 應該才是起步的適當轉速.

所以我說咱們的車主都是聰明有知識的
車主手冊都沒寫,沒定義的, 都給了答案....
我想老美只會跟你說, 你白紙黑字叫我
Drive away "without delay"
"Do not wait" for the engine to warm up
Start driving "right away"
說到
>1000 RPM is not "moderate engine speeds" ?
老美也會跟你說
Why you say >1000 RPM is not a moderate engine speed ?
Where is the definition ?
不是要玩文字遊戲抬槓,
覺得是正常就正常囉,
覺得要小心就要小心囉
P.S. 我的車起動轉速可沒超過 1500 轉, 頂多就在一千二附近,
