汽車停駛期間注意養護 要防止老化生銹

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。
