引擎過熱時的應急處理方法
發動機過熱是十分危險的緊急情況,運氣不好可能會將發動機破壞掉。在駕駛時,如果注意到水溫表的指針進入了紅區,居高不下,或反覆地在紅區震動,就必須采取緊急措施。
如果在普通公路上出現了發動機過熱現象,應該盡快地降低車速,把汽車駛到樹蔭下,或駛到相對比較涼快的地方,把汽車停下來。打開發動機罩蓋,讓發動機怠速運轉,等待發動機溫度逐漸恢復正常。在發動機水溫恢復正常之后,將發動機熄火。然后再等待一段時間,直到發動機的水溫充分地下降了之后,再檢查發動機的冷卻水量。這時發動機的冷卻水量大都嚴重不足。按著規定量把冷卻水補足之后,再檢查一下冷卻系統,確認沒有其他故障之后,才可以起動發動機,繼續行駛。
如果駕駛在高速公路上出現了發動機過熱現象,必須立刻把暖風全部打開並打開車窗,這樣,車廂溫度一般會急劇上升。由于有暖風幫助冷卻水散熱,能使冷卻水溫適當地下降到安全范圍以內。這樣可以繼續開車,同時找到最近高速公路的出口,把汽車駛到安全的場所停下來。
接下來,只要按照上述方法,使發動機的溫度降下來就行。注意選擇停車場所,最好不要把汽車停在路邊,以免影響交通或被撞車。
冷卻系統的故障是發動機過熱的直接原因。因此,定期檢查冷卻系統是很重要的,特別是在長途上路之前。
