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:

　　在怠速狀態(tài)下，車身抖動明顯。觀察排氣口，排出的廢氣有明顯的間隔，同時，排氣管抖動，能清楚地聽到“嘟嘟”的聲音。

　　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.

　　二是在駕駛過程中，車速低于2500轉(zhuǎn)，車身有明顯的抖動、加速軟弱;當轉(zhuǎn)速超過2500 RPM時，震動感消失。

　　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，打開發(fā)動機蓋，觀察發(fā)動機運行情況，發(fā)現(xiàn)發(fā)動機有明顯抖動。這種抖動明顯不屬于正常發(fā)動機工作狀態(tài)下的抖動，而且抖動范圍非常大。

　　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.

　　如果只有一個點火線圈故障，其他三個氣缸工作正常，幾乎沒有緊急駕駛的問題，但汽車發(fā)動機、底盤和連接部件都非常不利。寶萊指定的維修站站長建議車主暫時停止使用缸內(nèi)車輛，如果一個以上缸內(nèi)點火線圈被燒毀，建議立即停止駕駛。

　　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.

　　本文介紹了電火盤管的故障現(xiàn)象:

　　This paper introduces the fault phenomena of electric fire coil:

　　點火線圈燃燒電壓低，或不產(chǎn)生燃燒電壓，會造成發(fā)動機怠速不穩(wěn)定，間歇性失速，無法啟動。點火線圈常見故障包括:

　　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. 點火線圈繞組短路會使點火線圈產(chǎn)生的電壓過低，導(dǎo)致點火能量不足，導(dǎo)致火花塞電極過快變黑(經(jīng)常被積碳污染)。

　　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. 點火線圈損壞或接地，不產(chǎn)生高壓，不可能點火。

　　2. The ignition coil is damaged or grounded, so it is impossible to ignite without generating high voltage.

　　3.點火線圈表面放電是指點火線圈外表面放電跳躍現(xiàn)象。表面放電的主要原因是污垢和嚴重的潮濕。高壓絲杠附近經(jīng)常發(fā)生表面放電，因此高壓絲杠與高壓電線之間的連接通常帶有護套。當發(fā)生表面放電時，在放電部位常常可以看到燒傷痕跡。當燃燒損傷較輕時，可將其取出并絕緣。

　　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. 點火線圈絕緣老化。其原因是熱車后溫度過高或在高速重載條件下頻繁點火，導(dǎo)致點火線圈溫度迅速上升。然而,點火線圈本身的絕緣老化導(dǎo)致放電短路在高溫高壓下,導(dǎo)致減少的實際匝比點火線圈的初級繞組和二次繞組和二次繞組產(chǎn)生的電壓值減少,導(dǎo)致突然的失敗藐視失敗和速度。點火線圈工作溫度一般不超過80℃，否則會引起點火線圈過熱。點火線圈過熱會熔化點火線圈內(nèi)部的絕緣材料，加速點火線圈的損壞。

　　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.
