点火圈损坏会有什么样的症状?

  点火线圈损坏有什么症状?当你在车上看到以下症状之一时,你几乎可以看出点火线圈出了问题:
  What are the symptoms of ignition coil damage? When you see one of the following symptoms in the car, you can almost see that the ignition coil is out of order:
  在怠速状态下,车身抖动明显。观察排气口,排出的废气有明显的间隔,同时,排气管抖动,能清楚地听到“嘟嘟”的声音。
  In idle state, the body jitter is obvious. Observing the exhaust port, there is a clear interval between the exhaust gas. At the same time, the exhaust pipe is shaking, and the sound of "beep" can be clearly heard.
  二是在驾驶过程中,车速低于2500转,车身有明显的抖动、加速软弱;当转速超过2500 RPM时,震动感消失。
  Second, in the driving process, the speed is less than 2500 rpm, the body has obvious shaking and weak acceleration; when the speed exceeds 2500 RPM, the vibration disappears.
  第三,打开发动机盖,观察发动机运行情况,发现发动机有明显抖动。这种抖动明显不属于正常发动机工作状态下的抖动,而且抖动范围非常大。
  Thirdly, open the engine cover and observe the operation of the engine. It is found that the engine has obvious jitter. This kind of jitter obviously does not belong to the normal engine working state jitter, and the jitter range is very large.
  如果只有一个点火线圈故障,其他三个气缸工作正常,几乎没有紧急驾驶的问题,但汽车发动机、底盘和连接部件都非常不利。宝莱指定的维修站站长建议车主暂时停止使用缸内车辆,如果一个以上缸内点火线圈被烧毁,建议立即停止驾驶。
  If only one ignition coil fails, the other three cylinders work normally and there is almost no emergency driving problem, but the automotive engine, chassis and connecting parts are very disadvantageous. The station master designated by Baolai suggested that the car owner temporarily stop using the in-cylinder vehicle. If more than one in-cylinder ignition coil is burnt down, the driver should stop driving immediately.
  点火线圈故障
  Ignition coil failure
  本文介绍了电火盘管的故障现象:
  This paper introduces the fault phenomena of electric fire coil:
  点火线圈燃烧电压低,或不产生燃烧电压,会造成发动机怠速不稳定,间歇性失速,无法启动。点火线圈常见故障包括:
  Low combustion voltage of ignition coil or no combustion voltage will cause engine idling instability and intermittent stall, which can not start. Common faults of ignition coil include:

  1. 点火线圈绕组短路会使点火线圈产生的电压过低,导致点火能量不足,导致火花塞电极过快变黑(经常被积碳污染)。
  1. Short-circuit of ignition coil winding will cause the ignition coil voltage to be too low, resulting in insufficient ignition energy, resulting in too fast blackening of spark plug electrodes (often polluted by carbon deposition).
  2. 点火线圈损坏或接地,不产生高压,不可能点火。
  2. The ignition coil is damaged or grounded, so it is impossible to ignite without generating high voltage.
  3.点火线圈表面放电是指点火线圈外表面放电跳跃现象。表面放电的主要原因是污垢和严重的潮湿。高压丝杠附近经常发生表面放电,因此高压丝杠与高压电线之间的连接通常带有护套。当发生表面放电时,在放电部位常常可以看到烧伤痕迹。当燃烧损伤较轻时,可将其取出并绝缘。
  3. Surface discharge of ignition coil refers to the jump phenomenon of discharge on the outer surface of ignition coil. The main causes of surface discharge are dirt and severe dampness. Surface discharge often occurs near the high-voltage screw, so the connection between the high-voltage screw and the high-voltage wire often has a sheath. When surface discharge occurs, burn marks can often be seen at the discharge site. When the combustion damage is mild, it can be removed and insulated.
  4. 点火线圈绝缘老化。其原因是热车后温度过高或在高速重载条件下频繁点火,导致点火线圈温度迅速上升。然而,点火线圈本身的绝缘老化导致放电短路在高温高压下,导致减少的实际匝比点火线圈的初级绕组和二次绕组和二次绕组产生的电压值减少,导致突然的失败藐视失败和速度。点火线圈工作温度一般不超过80℃,否则会引起点火线圈过热。点火线圈过热会熔化点火线圈内部的绝缘材料,加速点火线圈的损坏。
  4. Aging of ignition coil insulation. The reason is that the temperature of the ignition coil rises rapidly because of the high temperature after the hot car or frequent ignition under the condition of high speed and heavy load. However, the insulation aging of the ignition coil itself leads to short-circuit discharge at high temperature and high pressure, resulting in a reduction in the actual turn voltage than the primary winding and secondary winding of the ignition coil, resulting in sudden failure and contempt for failure and speed. The working temperature of the ignition coil generally does not exceed 80 C, otherwise the ignition coil will be overheated. Overheating of the ignition coil will melt the insulation material inside the ignition coil and accelerate the damage of the ignition coil.
