短時間warm up還是有好處的

So, when you start that cold engine, it's essentially running without lubrication. If you start up and immediately put a load on the engine, things could get damaged. It's just not ready to go. Take a minute or two to get that oil pumping around before putting any load on the engine, and your pistons and camshafts and turbos and other spinning, moving bits will be much, much happier.

• 關鍵是坐在車裏預熱，人太冷了受不了。如果有遙控熱車。我還是喜歡車子裏暖洋洋時再坐進去。 -coorslight969- ♂ (0 bytes) () 01/22/2016 postreply 09:48:13

• 遙控熱車是好，多花些銀子方便，我這裏不冷，但是走到車前幾分鍾打著方便 -soccer88- ♂ (0 bytes) () 01/22/2016 postreply 10:10:54

• 覺得開著風扇下熱車水溫表上升反而慢，還是行車5分鍾以後再開風扇更有效率 -obamacome- ♀ (0 bytes) () 01/22/2016 postreply 20:20:53

• 我感覺發動機啟動十幾秒內機油就足夠散布了，剛啟動那一刹那感覺比較生硬。發動機怠速也一秒鍾十轉呢。 -二胡一刀- ♂ (0 bytes) () 01/22/2016 postreply 12:02:42

• 是滴，汽車的熱風大多來自引擎的餘熱，大冷天的誰願意坐在冰箱裏開5分鍾？ -US_CAR.- ♂ (0 bytes) () 01/22/2016 postreply 12:09:56

• 某些人插進鑰匙，點火，倒車，在一秒鍾搞定。多次提示，給發動機預熱那怕半分鍾。卻不聽。 -leslieking- ♂ (0 bytes) () 01/22/2016 postreply 15:38:51

• 看新車手冊隻說天冷啟車不要轟油門加速，也不建議怠速下熱車 -obamacome- ♀ (0 bytes) () 01/22/2016 postreply 20:12:16

• 至少要等到fast idle 結束再掛檔起步。 -US_CAR.- ♂ (0 bytes) () 01/22/2016 postreply 21:08:09

• 冬天了，已聽過很多早晨熱車而被盜竊的報導，有的回屋5、6秒鍾高檔車就被開走了，哈哈 -obamacome- ♀ (0 bytes) () 01/22/2016 postreply 20:06:09
