標題: 汽車停駛期間注意養護 要防止老化生銹 [打印本頁]

一些車主可能會因為一些特殊的原因,使自己的愛車閒置一段時間。不過,車閒人可不能閒。長期停駛的車輛,會因為受到大氣侵蝕而使各總成和機構的技術狀況逐漸變壞,以致失去原有的技術性能。為了減輕這種不良影響,車主應該經常對停駛的車輛進行必要的養護工作,以使其處於良好的性能狀況。

1、防止金屬生銹

銹蝕主要是空氣中的水分、氧氣以及腐蝕性物質的共同作用造成的。因此,對於長期停駛的汽車,應保持金屬表面清潔。停放車輛的車庫內應經常保持通風,使空氣相對濕度保持在70%以下。需及時清除汽車上的灰塵、髒物和水分。在易銹蝕的部位和機件表面應塗以機油、潤滑脂或者用油紙包紮起來。對於各總成機構上的孔隙,應加以密封,避免空氣、水分和灰塵進入內部。

2、防止橡膠製品的老化變質

汽車上的橡膠製品,如輪胎、傳動帶以及防塵罩等,經常會發生老化、膨脹或者為形現象,致使性能變壞,使用壽命變短。

像膠製品老化,主要是由於橡膠屬於不飽和的高分子碳氫化合物,容易吸收空氣中的氧而氧化,同時硫化橡膠還有一定的透氣性,氧容易進入內部起氧化作用。特別是直射陽光,能促使橡膠迅速老化。橡膠製品被汽油、機油沾污後,會導致體積膨脹,膠質變松,彈性下降。

為防止橡膠製品地老化,應避免陽光直接照射及礦物油接觸。

3、防止棉麻製品的霉爛及地毯等,都很容易吸收水分。特別是在潮濕地區和陰雨季節,更易受潮霉變。因此車主應對車上的棉麻製品經常檢查,適時晾曬,保持乾燥。

4、防止汽油的抗爆性能降低

汽油的抗爆性能決定於汽油辛烷值的高低。汽車長期停駛,汽油的辛烷值會隨著輕質成分的損失和膠質含量的增加而下降,從而使其抗爆性隨之降低。因此,汽油油箱要嚴密封閉,並且避免溫度過高。汽油儲存的時間最好不要太長。

5、經常檢查發動機的工作狀況

每月至少起動發動機一次,怠速運轉4-5min,檢查發動機的運轉情況。如有異常現象,需及時調整、維修。

另外,還要經常檢查蓄電池。蓄電池的電解液液面必須高於極板10-15mm,不足時應及時添加蒸餾水,應保持電量充足,必要時應對蓄電池充電。
