The car just changed the ignition coil and then ate it out of the why

Wiring method: 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.

2. Working principle The reason why the ignition coil can turn the low voltage electricity on the car into high voltage is because it has the same form as the ordinary transformer, and the number of turns of the primary coil and the secondary coil is large. However, the ignition coil works in a different way than the ordinary transformer, which works continuously, while the ignition coil works intermittently, and it repeatedly carries out energy storage and discharge at different frequencies according to the different speed of the engine. When the primary coil is connected to the power supply, a strong magnetic field is generated around it as the current increases, 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 greater the current at the moment of current disconnection, and the greater the turn ratio of the two coils, the higher the voltage induced by the secondary coil.

Excerpt from Encyclopedia.

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.

Hello, the car is shaking. Boring.

Hello, the vehicle is shivering and boring, hope it can help you.

Serious lack of cylinders, the kind of driving that is not bad.

Engine cylinder deficiency mainly refers to the engine has one or more cylinders that are not working properly. It is usually manifested as: abnormal engine work or insufficient power, uneven engine work and rhythmic vibration at high, medium and low speeds, muffler exhaust black smoke and fire.

The lack of cylinders in the engine will bring great harm: 1The speed and power of the engine decreased.

2.Increased fuel consumption and emissions of pollution. 3.

Aggravate the wear of running parts and shorten the service life of lubricating oil.

The lack of cylinder in the engine can lead to large fuel consumption, black smoke, weakness, horsepower decline, the vehicle cannot increase speed, serious shaking, and increased driving noise. And it is very bad for driving safety. Especially on the road section that needs to be sloped, the engine load of the vehicle with a lack of cylinder increases, the body shake is more obvious, and it is very easy to have an instantaneous dead fire.

Hello, check if there is a short circuit in the line.

1. Common ignition fault phenomena.

1. The engine has poor running stability, deflagration and easy overheating.

2. If there is reversal, idling and deflagration when the engine starts at the time of rapid acceleration, it is premature ignition.

3. The engine is stuffy and weak, easy to overheat, the exhaust pipe emits black smoke, and the ignition is too late.

2. Troubleshooting and diagnosis of fault causes.

1) Cause of failure:

1. Improper adjustment of ignition timing, adjustment of ignition timing;

2. If the ignition advance angle centrifugal adjustment device on the distributor fails and the vacuum adjustment device fails or the pipeline connection is not sealed, the adjustment device should be overhauled. Among them, improper ignition timing adjustment is the most common.

3. Improper diagnosis method of engine ignition time:

4. Use the ignition timing instrument for detection.

2) Maintenance and fault judgment.

Phenomenon: The engine is not running smoothly, there is a reversal when the engine starts, and there is a deflagration at idle speed and rapid acceleration, which is premature ignition.

Elimination method: connect the ignition tester, adjust the ignition and hand it over to the specified value in advance.

Ignition is too late and repaired.

Phenomenon: the engine is stuffy and overheated, the exhaust pipe emits black smoke, and the ignition is too late when the gun or carburetor is tempered.

Exclusion method: Connect the ignition tester to adjust the specified value of the ignition advance corner.

See if the spark plug is the best part.

Hello friend, if you don't replace an ignition coil separately, there will be a misfire.

First, if the ignition coil of the vehicle is damaged, this is generally enough to replace one separately, and there is no need to replace them all.

Second, if there is a fire failure when replacing one, it means that the other ** coils are also faulty.

Why does just changing an ignition coil catch fire.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

We hope you find this answer helpful. Your family is happy, the Year of the Tiger Hello friends, there is no mega model search to replace an ignition coil alone, there will be a fire first, if the vehicle ignition coil is damaged, this is generally replaced separately, there is no code defeat necessary to replace all the second, if the replacement of a or the failure of the fire family calendar, it means that the other ** coils correspond to faults.

Maybe I changed an ignition coil of poor quality, on the highway for the vast fire, bought online for a bargain.

Then this is the quality problem of the ignition coil.

The vast number of mergers are missing.

If it is an analogue, then the general quality is not reliable.

Answer: If the ignition coils of all cylinders are one, then if one is damaged, all of them need to be replaced. If each cylinder has a separate ignition coil, then only the damaged one needs to be replaced. The ignition coil belongs to the ignition system of the car, and the ignition coil is connected with the spark plug.

The function of the ignition coil is to raise the voltage, only then the spark plug will have enough ignition energy. Although the ignition coil is not a wearing part that needs to be replaced regularly, the ignition coil is easily damaged when it runs in a high-temperature environment for a long time.

If it is four in one, it can only be replaced in full, and the individual can be replaced separately.

The reason why the ignition coil can turn the low-voltage electricity on the car into a high voltage is that it has the same form as the ordinary transformer, and the primary coil has a larger number of turns than the secondary coil. There are two sets of coils in the usual ignition coil, the primary coil and the secondary coil.
