line-height: 1.1; color: rgb(0, 0, 0); outline: 0px !important;">2015 年长安 CS35，行驶 3 万公里。<p style="box-sizing: border-box; margin-top: 0pt; margin-bottom: 0pt; font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 16px; line-height: 1.29; color: rgb(0, 0, 0); outline: 0px !important;"><p style="box-sizing: border-box; margin-top: 3.95pt; margin-bottom: 0pt; margin-left: 1.35pt; font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;

font-size: 12pt; text-align: justify; line-height: 1.18; color: rgb(0, 0, 0); text-indent: 23.9pt; outline: 0px !important;">根据车主描述，此车前一段时间故障现象为冷车难启动，热车后正常行驶。 故障现象大概持续了 5 天左右，后车辆无法启动，排气管有明显燃油味。接车后 我们先是对车主描述的故障现象进行验证，发现启动机工作正常，车辆无法启动， 使用 X431 诊断仪对故障码进行读取，结果为无故障码。<p style="box-sizing: border-box;

margin-top: 0pt; margin-bottom: 0pt; font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 16px; line-height: 1.3; color: rgb(0, 0, 0); outline: 0px !important;"><p style="box-sizing: border-box;

margin: 1.3pt 72.2pt 0pt 25.3pt; font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 12pt; line-height: 1.15; color: rgb(0, 0, 0); text-indent: 0.7pt; outline: 0px !important;">1.对曲轴凸轮轴位置传感器电源信号进行检查没有发现异常。 2.点火线圈均有高压火。<p style="box-sizing: border-box; margin: 1.3pt 3.1pt 0pt 2.3pt; font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 12pt; line-height: 1.15; color: rgb(0, 0, 0); text-indent: 23.1pt; outline: 0px !important;">3.拆下火花塞进行检查，发现都已经被汽油淹灭，2 缸特别严重，燃烧室中 明显可以看到燃油积液。<p style="box-sizing: border-box; margin: 1.55pt 1.15pt 0pt; font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 12pt; text-align: justify; line-height: 1.19; color: rgb(0, 0, 0); text-indent: 23.9pt; outline: 0px !important;">4.怀疑喷油嘴损坏，拆下后发现 2 缸在打开点火开关后处于一直喷油状态， 可持续 3 秒左右且没有雾化，启动时其他 3 缸喷油量也较多。对每个喷油器插头 电压进行测量得到，1.3.4 缸电压 8V，2 缸 12V 喷油器处于一直打开状态，对调 其他喷油嘴故障依旧，因此可以排除 2 缸一直喷油不是喷油器损坏导致。通过查 找电路图得到，4 个喷油器是电脑控制负极且中间没有插接件，常电源是油泵继 电器供给。随后测量了喷油器插头到电脑的控制线阻值均小于 1 欧姆，正常，插 上电脑插头后 2 缸控制线对地电阻 90 欧姆，1、3、4 缸均为 0 欧姆，得到结论  为电脑内部损坏导致淹缸，无法启动。<p style="box-sizing: border-box;

outline: 0px !important;">该车虽然行驶公里仅 3 万电脑却已经损坏，再加上没有任何故障码，导致很 难第一时间判断故障点，在遇到这种故障时我们应先对几个必要条件进行排除， 再搞清楚其控制方法，依次排除缩小故障范围，才能准确找到故障点，切不可盲 目换件试车。
