甲醇汽油对汽车发动机金属材料腐蚀的测定

The laboratory determination method of corrosion rate for metallic materials in automobile engines by using methanol gasoline

针对甲醇汽油腐蚀性问题进行研究,提出一种使用减重法测定其对涉及汽车发动机的几种金属材料在特定条件下产生腐蚀的腐蚀率,以表征其腐蚀性大小的方法。为解决甲醇汽油腐蚀问题提供切实可行的试验方法,以便寻找适宜的添加剂予以解决。

This paper examines the corrosion problems of methanol gasoline,proposes a deweighting method which can represent the corrosion rate for metallic materials of auto-related engines under defined conditions.It provided a feasible test method in solving the corrosion problems by methanol gasoline with suitable gasoline additives.
