Are car ignition coils and high voltage packs one thing?

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.

It's a thing, and its scientific name is an ignition coil.

It is commonly known as the high-pressure pack. Hope it helps.

Not universal, different for every car.

The ignition coil is equivalent to an autotransformer, which converts 12V low-voltage DC into 15 20kV high-voltage DC. According to the different structural forms of the magnetic circuit, the ignition coil can be divided into two types: open magnetic circuit type and closed magnetic circuit type. In the traditional ignition system, the open magnetic circuit ignition coil is widely used, and the closed magnetic circuit ignition coil is mostly used in the electronic ignition system.

a) Open magnetic circuit ignition coil.

The open magnetic circuit ignition coil is mainly composed of primary winding, secondary winding, iron core and additional resistor. Simple structure, low cost and convenient processing. However, due to the large leakage flux, the conversion efficiency is low, and it is not suitable for the ignition system of modern gasoline engines.

b) Magnetic circuit ignition coil.

The magnetic circuit ignition coil adopts a "sun" shaped core, with the primary winding wound inside and the secondary winding wound on the outside of the primary winding. In the case of the same primary energy, the energy obtained by the secondary stage is large, and the energy conversion efficiency is high. In addition, the closed magnetic circuit ignition coil is small in size and compact in structure, and is widely used in electronic ignition systems.

Ignition coils and high-voltage packets, commonly known as 'lift', are a device that converts low-voltage electricity into high-voltage electricity.

Ignition coils and high-voltage packs are one thing.

There is a certain relationship between high-voltage no fire and high-voltage package, if it is a loading test, there may be other reasons, look at the shape of this high-voltage package, your car should be a carburetor, if there is no high-voltage current in the loading test, it is also implicated in whether the ignition module is faulty, if it has been removed from the car and tested to high voltage without current, it is generally a problem with the high-voltage package.

Forgive me for being a shallow learner, why do I think the two things you are talking about are one Ah, different names, the previous car is a high-voltage coil to produce high voltage, through the high-voltage line to the distributor, and then the distributor is output to each cylinder, and then there is an integrated one, the two sections of a coil are each tube a cylinder, the four-cylinder car is 2 secondary windings, the 6-cylinder car is 3, and the more advanced is the independent ignition, one cylinder, one cylinder.

The ignition coil of the car, which can only be found in gasoline vehicles, is actually a transformer, which is a two-pole coil, which can change the voltage from 12V to 1300V (instantaneous) after being energized, which plays the role of ignition.

Ignition coils are available in dry and wet types! The dry type is mainly composed of a primary coil (a small number of turns of copper wire) and a secondary coil (a large number of turns of copper wire) and an iron core! The wet type also has primary coils, secondary coils, iron cores, and insulating oil insulating paper!

In layman's terms, the ignition coil is a high-voltage pack. Because this is the key coil for the low voltage to rise to the high voltage.
