car ignition coil price
This question is what many customers who want to buy car ignition coils want to pay attention to, but if you ignore the quality just for the price, it is not worth it. If you buy an ignition coil from a supplier, there is a problem with after-sales, unless you encounter a reliable ignition coil supplier. If you want to know the price of car ignition coils, it is recommended to find a car ignition coil manufacturer with many years of experience, because of the quality of the purchased products, after-sales guarantee, technical guidance, one-to-one communication, and other services.

car ignition coil failure
The ignition coil manufacturer will tell you what causes the failure and what are the corresponding solutions.
Fault 1. There is no response after loading, and the engine cannot be started
1. The plug is in poor contact with the coil socket on the car, especially when several high-voltage lines on the same car are not working and the ignition coil is not in contact.
2. The primary circuit of the ignition coil is damaged and cannot work.
3. The ignition coil module is damaged after working and cannot work.
4. The low-voltage part of the ignition coil is soldered, and the aging effect or vibration or light work leads to de-soldering.

Fault 2. Engine shaking, body shaking
1. The engine lacks a cylinder, and only part of the ignition coil is working in the cylinder.
2. After the ignition coil works for a period of time, an inter-turn short circuit occurs.
3. The high-voltage line leaks electricity, and the energy loss is too large, resulting in insufficient breakdown voltage, which is easy to damage the spark plug.
4. The spark plug has serious carbon deposition, and the spark plug gap is difficult to break through. Spark plugs should be replaced at 30,000 km, and TSI must be replaced at 20,000 km.
5. The low-voltage plug of the ignition coil is in poor contact with the external circuit, the high-voltage output is in poor contact with the high-voltage line, and the ignition coil circuit is not smooth, which affects the normal use of the ignition coil.

Other faults:
1. A short circuit of the spark plug will directly lead to an increase in the current of the ignition coil and a short circuit;
2. The high-voltage line is short-circuited to ground (when the iron is struck), which will cause the ignition coil current to increase and short-circuit;
3. If the power supply voltage is too high, the current of the primary circuit will be too large, which will cause abnormal heating and burst the ignition coil;
4. The spark plug is an open circuit (more carbon deposits), which will lead to an increase in the load of the ignition coil, which will lead to failure due to long-term overload;
5. If the high voltage line is disconnected, the high voltage generated by the ignition coil cannot be released, and the voltage accumulates and discharges to the ground, causing a failure;

The solution to the fault of the automobile ignition coil
1. If only one ignition coil fails, the remaining three cylinders work normally, and reluctant emergency driving is not a problem, but it is very unfavorable to the engine, frame, and connecting parts of the car. It is recommended that car owners temporarily stop using vehicles with insufficient cylinders. If the ignition coil of more than 1 cylinder is burned out, it is recommended to stop driving immediately.
2. Driving a vehicle that lacks cylinders due to ignition coil failure is very detrimental to driving safety. On the uphill section, especially on the road section that needs to "start from the slope", the engine load of the cylinder-deficient vehicle increases, the body shakes more obviously, and it is very prone to the instant dead fire. If you really have to move the vehicle, you should try to keep the speed above 2500 rpm as much as possible.

car ignition coil life
Under normal circumstances, each cylinder is equipped with a set of ignition coils and spark plugs. The service life of the ignition coils is generally 100,000 kilometers or even longer. Based on the protection of the ignition coils, the following aspects should be paid attention to when driving: Prevent the ignition coils from heating or damp; do not turn on the ignition switch when the engine is not running; frequently check, clean, and fasten the line connectors to avoid short circuit or grounding; control the performance of the engine to prevent excessive voltage; Moisture can only be wiped dry with a cloth, and must not be baked with fire, otherwise the ignition coil will be damaged.

The automotive ignition coil structure
1. Open the magnetic circuit ignition coil
The open magnetic circuit ignition coil adopts a cylindrical iron core. The magnetic flux generated by the primary winding in the iron core forms a magnetic circuit through the magnetic conductive steel sleeve, and the magnetic lines of force on the upper and lower parts of the iron core pass through the air, and the magnetic resistance of the magnetic circuit is large. The leakage of magnetic flux is large, and the conversion efficiency is low, generally only about 60%. According to the number of low-voltage terminals, there are two types of terminals: two-terminal type and three-terminal type. The three-terminal ignition coil is equipped with an additional resistor, and its low-voltage terminals are marked with "-", "+" and "+ switch" respectively, and the additional resistor is connected between "+" and "+ switch"; two The terminal type ignition coil has no additional resistance, only two terminals marked with "+" and "".
2. Closed magnetic circuit ignition coil
In recent years, closed magnetic circuit ignition coils with high energy conversion efficiency have been used in electronic ignition systems of automobiles. Compared with the traditional ignition coil, its iron core is in the shape of a "mouth" or "say" with a small air gap. The magnetic flux generated by the primary winding in the iron core forms a closed magnetic circuit through the iron core, which reduces the leakage loss, so The conversion efficiency is high, up to 75%.In addition, the closed magnetic circuit ignition coil also has the advantages of small size, lightweight, and little interference to the radio.
