为了提高检查和修理进口汽车电器设备的工作效率,汽车电路中用的电线采用多种颜色。由于进口汽车的电珞复杂,单色线不能满足需要,因此在单色线基础上采用了复合线色,即基准色电线上中间部分有一条辅助色条纹;或者在单色线线端套上其它颜色套管,以区别于单色线。在汽车电路图中电线颜色采用英文字母表示,单个字母表示单线色,两个字母表示复合线色。即:第一个字母为基准色,第二个字母为辅助色;若加彩色套管则用一个分数形式表示,分子字母表示线
In order to improve the efficiency of inspection and repair of imported automotive electrical equipment, the wires used in automotive circuits are available in a variety of colors. Due to the complexity of the imported car electrical Luo complex, monochrome line can not meet the needs of the monochrome line on the basis of a composite line color, that is, the middle of the reference color wire has an auxiliary color stripes; or monochrome wire end sleeve Other color sleeves to distinguish them from monochrome lines. In the car circuit diagram wire color using English letters, a single letter that single-color, two letters that compound line color. Namely: The first letter is the base color, the second letter is the auxiliary color; if adds the color sleeve, then uses a fraction form to express, the molecular letter represents the line
