当汽车出现一定的故障的时候，车友们也不会去自己检测，排除故障等，下面就是小编给车友们整理的一些关于汽车点火线圈的一些常见的故障分析，车友们需要了解这方面的问题，当汽车出现一定的故障的时候也不至于束手无策。
When there is a certain fault in the car, the car friends will not go to their own detection, troubleshooting and so on. Here are some common fault analysis about the car ignition coil arranged by Xiaobian for the car friends. The car friends need to understand this problem, and when there is a certain fault in the car, they will not be helpless.
点火线圈故障现象
Ignition coil failure
点火线圈如果使用方法不当，会造成点火线圈损坏，因此应注意以下几点：防止点火线圈受热或受潮;发动机不运转时不要开点火开关;经常检查、清洁、紧固线路接头，避免其短路或搭铁;控制发动机性能，防止电压过高;火花塞不得长期“吊火”;点火线圈上的水分只能用布擦干，绝不能用火烘烤，否则会损坏点火线圈。
If the ignition coil is used improperly, it will cause damage to the ignition coil. Therefore, the following points should be paid attention to: prevent the ignition coil from being heated or damped; do not turn on the ignition switch when the engine is not running; frequently check, clean and fasten the circuit connector to avoid short circuit or grounding; control the engine performance to prevent high voltage; do not hang the spark plug for a long time; The moisture on the ignition coil can only be wiped dry with a cloth, and must not be baked with fire, otherwise the ignition coil will be damaged.
直观判断点火线圈故障： 通过观察点火线圈外观，如有异常物质溢出、绝缘盖或外壳破裂，高压输出端有烧蚀痕迹等现象，应予更换。
Visual judgment of ignition coil fault: observe the appearance of ignition coil, and replace it if there is any abnormal material overflow, insulation cover or shell rupture, and ablation trace at high-voltage output end.
现象一：溢胶
Phenomenon 1: glue overflow
现象二：爆裂
Phenomenon 2: Burst
现象三：高压连接管烧蚀
Phenomenon 3: ablation of high pressure connecting pipe
现象四：高压嘴烧蚀
Phenomenon 4: high pressure nozzle ablation
二、高压试火：
2、 High pressure fire test:
进行高压试火时，应先确认控制信号是否正常。同时应做好绝缘保护工作，直接用手接触高压线容易造成电击。
During the high-pressure fire test, confirm whether the control signal is normal. At the same time, insulation protection shall be done well, and direct contact with high-voltage line by hand is easy to cause electric shock.
三、替换法：
3、 Replacement method:
1、使用规格相同，性能良好的线圈代替可能有故障的线圈，进行比较判断。若替换后，故障现象消除，则说明被替换的线圈可能已损坏。
1. The coils with the same specification and good performance are used to replace the coils with possible faults for comparative judgment. If the fault is eliminated after replacement, the replaced coil may be damaged.
2、使用此方法时，若属于插头连接的不可靠因重装时被修正，或者高压线、插头漏电破损点因为重新装配而与之前的易放电连接点发生改变的，则有可能影响到对线圈的判断。此时可将该线圈装于其它车辆上进行故障复现，做更终确认。
2. When using this method, if the unreliability of plug connection is corrected during reassembly, or the leakage damage point of high-voltage line and plug is changed from the previous easily discharging connection point due to reassembly, it may affect the judgment of coil. At this time, the coil can be installed on other vehicles for fault recurrence and final confirmation.
