What brand is the ignition coil of the car electric? All right?

International: Bosch, Delphi, AC, Marelli, Denso, Valeo and other international brands;

2. Domestic: Wanshiyi, Juhuowang, Ondi, Gangwan, Jinhuo, GEW and other domestic brands;

3. With the development of automobile gasoline engines in the direction of high speed, high compression ratio, high power, low fuel consumption and low emissions, the traditional ignition device has not adapted to the requirements of use. The core components of the ignition device are the ignition coil and the switching device, and the spark plug can produce a spark of sufficient energy to increase the energy of the ignition coil, which is the basic condition for the ignition device to adapt to the operation of modern engines;

4. There are two sets of coils in the usual ignition coil, the primary coil and the secondary coil. The primary coil uses thicker enameled wire, usually about 200-500 turns of enameled wire about millimeters; The secondary coil uses a thinner enameled wire, usually about 15000-25000 turns with about millimeter enameled wire. One end of the primary coil is connected with the low-voltage power supply (+) on the vehicle, and the other end is connected with the switchgear (cut-off).

One end of the secondary coil is connected with the primary coil, and the other end is connected with the output end of the high-voltage line to output high-voltage electricity;

5. The reason why the ignition coil can turn the low-voltage electricity on the car into a high voltage is because it has the same form as the ordinary transformer, and the number of turns of the primary coil is larger than that of the secondary coil. However, the ignition coil works in a different way than the ordinary transformer, the working frequency of the ordinary transformer is fixed at 50Hz, also known as the power frequency transformer, and the ignition coil works in the form of pulses, which can be regarded as a pulse transformer, which repeatedly carries out energy storage and discharge at different frequencies according to the different speed of the engine;

6. When the primary coil is connected to the power supply, a strong magnetic field is generated around it with the growth of current, and the iron core stores the magnetic field energy; When the switchgear disconnects the primary coil circuit, the magnetic field of the primary coil decays rapidly, and the secondary coil induces a very high voltage. The faster the magnetic field of the primary coil disappears, the larger the current at the moment of current disconnection, and the larger the turn ratio of the two coils, the higher the voltage induced by the secondary coil;

7. The ignition coil is divided into two types: open magnetic type and closed magnetic type according to the magnetic circuit. The traditional ignition coil is of the open magnetic type, and its core is stacked with silicon steel sheets of about millimeters, and the core is wound with secondary and primary coils. The closed magnetic type uses a similar iron core to wind the primary coil, and then winds the secondary coil outside, and the magnetic field lines form a closed magnetic circuit from the iron core.

The advantages of closed magnetic ignition coil are less magnetic flux leakage, small energy loss and small volume, so the electronic ignition system generally adopts closed magnetic ignition wire.

The ignition coil is composed of the main coil, the secondary coil, the magnetic core, the switching triode and other auxiliary components, the main coil is charged by the battery, the secondary coil is discharged and the spark plug is ignited, and the triode is responsible for switching. The charging time is controlled by the battery voltage and engine speed to ensure that the energy of each charge is consistent, the ignition coil has two kinds: 3 wires and 4 wires, 3 wires are positive and negative for the power supply, and the switch controls the ECU instruction, and the 4 wires have an additional ignition detection line, which can detect whether the spark plug is ignited and whether there is a discharge current in the secondary coil.

To put it simply, the ignition coil is a transformer, that is, the voltage of tens of volts is raised to tens of thousands of volts, but the voltage input to the primary coil is provided by the electronic ignition.

2: The reason why the ignition coil burns out.

Mainly the aging breakdown of the insulation layer or the damage of the switching triode, the large spark plug gap will lead to the main coil load, large heating, fast aging of the insulation layer, small spark plug gap leads to large discharge current of the secondary coil, fast heating, fast aging of the insulation layer, the assembled ignition coil may have poor durability of insulating materials, large internal resistance of the coil and fast heating, and the life of the transistor will be shorter if the quality is not high.

If it is always burned out, and it burns out soon after replacement, and why?

Let's take a look at the problem of the generator first, if the power generation is too high, the load of the ignition coil is too heavy, it is easy to burn out, but if the power generation is too high, then the body electrical appliances, such as light bulbs, will often be damaged; Of course, the quality of the accessories is not ruled out, so it is best to measure the power generation first.

If the spark plug gap is too large, adjust the gap or replace the spark plug.

The quality of gasoline is not good, try to change to high-grade gasoline.

If the compression ratio of the cylinder is wrong, adjust the compression ratio.

If there is a program failure in the computer version, you can go to the repair shop and use the computer to test the car and clear the wrong information. If it doesn't work, it may be that there is a problem with your car's transmission.

The power supply voltage is unstable.

The resistance of the high voltage is abnormal, replace the high voltage line.

There is a short circuit in the secondary.

The ignition coil is overheated due to the high primary current of the ignition controller.

It does not work well when subjected to high temperature and high pressure waves.

There is a small chance that it is a problem with the coil itself, so you can try a different brand.

The ignitor manifold does not work well.

The function of the ignition coil is to convert low-voltage electricity through the coil into a high-voltage power supply that can ignite the mixture. The function of the distributor is to transmit the high-voltage electricity to the cylinder that needs to ignite the mixture through the cylinder distribution line according to the set law.

The distributor transmits the high voltage to the cylinder to work, and the ignition coil is the coil that generates the high voltage, like a transformer, there are two sets of coils, primary and secondary.

Summary. Hello, I am glad to answer for you, the ignition coil brand on the market can be described as mixed, full of this kind of fake and shoddy products, and how to choose a good ignition coil brand is the first step for car owners to avoid lightning. In addition to the ignition coils of the original manufacturers of various car companies, spark plugs of brands such as Bosch, Delphi, and NGK are all very trustworthy brands in terms of quality and reputation.
