Symptoms of broken ignition coil
1. The cylinder corresponding to the ignition coil is not working. When idling, the valve is weak, unable to add fuel, and the fault light is on.
2. The ignition coil has leakage, and sometimes it may or may not shake during idle, but it will definitely shake when the fuel door is filled, and it is very weak.
3. When accelerating, there may be a power outage, causing the acceleration to tremble.
4. At the same time, when the cylinder is short, the mixture of gasoline and air in the cylinder cannot be ignited and will be discharged from the exhaust pipe. In fact, the temperature of the exhaust pipe is very high. When the mixed gas reaches the exhaust pipe, it will burn due to the high temperature in the exhaust pipe. At this point, the large amount of heat generated by combustion will block the three-way catalytic pores in the exhaust pipe, leading to the failure of the three-way catalytic system.
In addition, if the ignition coil is broken, the engine will vibrate severely, just like a tractor; Fuel supply, the car lacks power; Shake, unable to start at the high-end position; If it is broken, the fault light will light up; Refuel, sit well, and run forward. The car will creak, the engine will shake at idle, and the exhaust will smell of gasoline.
Correct ignition coil method:
The ignition coil, commonly known as the high-voltage package, is like a transformer that converts the battery's electricity into high voltage, and then the gasoline engine can ignite. Without an ignition coil, the fire cannot start.
The ignition coil is actually a transformer that converts a car's 12 volts to 233.3543 million volts. The car ignition system uses this high voltage to ignite the mixture in the cylinder.
