Ignition coils are called compact power transformers. They are designed to convert the low 12V voltage commonly found in car batteries to a higher voltage to ignite and start the engine. Each spark plug in the car has a corresponding ignition coil to work with. In this article, we will discuss the ignition coil, so you will understand its basic working principle and failure behavior.
Ignition coils are called compact power transformers. They are designed to convert the low 12V voltage commonly found in car batteries to a higher voltage to ignite and start the engine. Each spark plug in the car has a corresponding ignition coil to work with. The coil is either connected to the spark plug by wire or is located on top of the spark plug without the use of wire. The spark plug requires a voltage of about 15,000 to 20,00V to emit a spark of sufficient strength. If there is no ignition coil with good performance, it will lead to increased fuel consumption or engine fire. It is important to note that a faulty ignition coil can also be associated with a low voltage or abnormally high voltage battery, which can also cause a host of other problems in the car. The problem can be solved by replacing the battery. In used cars, many batteries deteriorate with age. If the battery voltage is lower than 12.65V after a full charge, there may be a problem with the battery.
1. Tempering A car's tempering may be an early sign of ignition coil failure. A car backfire occurs when the engine burns unused fuel in the cylinder and leaves through the exhaust pipe. If this problem is not addressed, it may lead to more serious problems later on. Tempering problems can usually be detected by the black smoke emitted from the exhaust pipe. The smell of gasoline in the smoke may also indicate a faulty ignition coil.
2. Poor fuel economy Another sign of ignition coil failure is poor fuel economy. If your vehicle gets significantly less mileage after a full tank of gas, it could mean that the ignition coil is malfunctioning.
3. Engine fire Engine fire occurs in vehicles with faulty ignition coils. Trying to start the engine of such a vehicle will cause the engine to catch fire and will sound particularly noisy. The car shakes at high speeds. Vehicles with faulty ignition coils can also jitter at idle.
4. The failure of the ignition coil of the car may also cause the car to stall. The reason this happens is because the coil sends an abnormal spark to the spark plug. The car would suddenly stall and it would be very difficult to start it again.
5. Idling instability and lack of power Engine idling instability and lack of power is also the fault performance of the ignition coil.
6. Check engine light on/Failure code Usually, the check engine light on the instrument panel will light up. The fault code for the engine is displayed when scanned with the car diagnostic tool.
According to different working principles and application scenarios, ignition coils can be divided into many types. Among them, the common ignition coil types include: oil-immersed ignition coil, dry ignition coil, signal sticking ignition coil and so on. Different types of ignition coils have different characteristics and application ranges, and can meet different actual needs.
