In electronically controlled engines, ignition coils are usually divided into twin-cylinder factory coils and independent ignition coils. Generally, one ignition coil is responsible for one cylinder, and some models share one ignition coil for two cylinders. If only one ignition coil fails and the rest work normally, then barely emergency driving is not a problem, but the car will vibrate, it will cause excessive fuel consumption, and it will affect the car's engine and connected components. If there is another ignition coil strike, it will not be far from the automatic shutdown, so once the car engine suddenly shakes, it is best to check the ignition coil yourself or go to an auto repair shop.

Who doesn't want to sit in the car, calm, full of power and comfortable, can listen to songs and enjoy the pleasure of driving, but the engine vibrates violently, just like a tractor; fuel the car, the car is weak, shakes, can't go to high gear, refuel the car Sit back, then move forward, the car churns, the engine vibrates when idling, and the exhaust gas smell is very strong, which seriously affects the driving mood. At the same time, it may lead to the lack of fire in a certain cylinder of the engine, and the lack of cylinders of the engine. When running, the idling jitter is severe, the power of the vehicle is insufficient after running, and the fuel consumption is also large.

In the process of daily driving and car maintenance, we must also do a good job of protecting the ignition coil. When driving at ordinary times, you need to pay attention to prevent the ignition coil from being heated or damp. When the engine is not running, do not turn on the ignition switch. Always check, clean, and fasten the line connectors to avoid short circuits or grounding. It is necessary to control the performance of the engine and prevent the voltage from being too high. In addition, the spark plug must not "hang fire" for a long time. When we do the maintenance of the ignition coil, we should pay attention to the moisture on the ignition coil can only be wiped dry with a cloth, and must not be baked with fire, otherwise the coil block will be damaged.

Every part of the car is very important and will affect our driving safety, so we must do a good job in the maintenance of the car and its parts to keep the vehicle in a "healthy" and "safe" state.
