A precursor to a broken ignition coil?

There are mainly these signs before the ignition coil breaks: slight car shaking, unstable idling, weak start, etc., and serious ones may not ignite.

The precursor of the ignition coil failure is mainly the weakening of the spark plug jumping ability, with the weakening of the spark plug jumping ability, the combustion of the combustible mixed gas of the engine will be affected, resulting in adverse reactions such as increased fuel consumption and decreased power.

The weakening of the spark plug's ability to skip fire results in incomplete combustion of the combustible gas mixture, which produces a coking substance called carbon deposit. As the core component of the engine ignition system, the automobile ignition coil plays the role of intermittently converting the vehicle's low-voltage electricity into high-voltage electricity. If the engine does not have the high-voltage electricity generated by the ignition coil, the flammable gas mixture in the cylinder will not be able to be broken down and ignited, and the engine will not be able to do its work normally.

Hope it helps, hope, thank you!

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.

Unstable idling, engine shake, weak acceleration, etc. can be a precursor to a broken ignition coil.

What are the symptoms of a broken ignition coil? Put a glass of water on the engine at a glance.

A car with a broken coil will shake, idle unsteadily, start weakly, and even fail to ignite in serious cases. There are several situations when the ignition coil is broken:1

The cylinder does not work, and the ignition coil does not produce sparks, which will cause the engine to shake seriously when working, and the accelerator pedal is weak. 2.The ignition coil leaked, and the engine shook very badly when the throttle was filled.

For these problems, it may not affect the normal use of the vehicle, but it is recommended to repair these problems in time.

What are the symptoms of a broken ignition coil? Put a glass of water on the engine at a glance.

The precursors of a broken ignition coil are body shake, exhaust pipe shake, and engine shake.

The ignition coil works by converting the low-voltage electricity of the power supply into high-voltage electricity, and the high-voltage electricity becomes a high-voltage electric spark through the spark plug, igniting the combustible gas mixture. The most obvious feature of the ignition coil failure symptom is that the engine lacks cylinders, and the engine may have obvious sudden sound when idling.

If you feel it most clearly on the exhaust pipe with your hand, and it is accompanied by a lot of engine shaking, then you can tell that the ignition coil may be broken. The ignition coil is broken, the car is moving, the higher the gear, the more obvious the frustration of the car when refueling, the engine shakes badly, and it is slightly better to give oil smoothly, and the case of fierce oil is the most experienced, and even has the feeling of turning off.

Ignition coil daily maintenance and replacement cycles

The simple explanation of an ignition coil is that the spark plug is able to "create a spark" that ignites the part of the cylinder that mixes the gas. In fact, it is responsible for converting the low-voltage current of the car into a transformer of high-voltage electricity, under normal circumstances, each cylinder is equipped with a set of ignition coils and spark plugs, the ignition coil of the old car will generally be replaced in 100,000 kilometers or even longer, the current car has improved the technology, some ignition coils are not bad for life, so as long as the ignition coil works normally, there is no need to replace it.

The failure of the ignition coil is often due to the poor quality of the fuel, and the fuel cannot be fully combusted, resulting in excessive carbon deposition in the spark plug, and the ignition coil will be broken down and the ignition coil assembly will be damaged. When laughing at the car, you need to pay attention to prevent the ignition coil from being heated or damp, do not turn on the ignition switch when the engine is not running, and often check, clean and tighten the line joints to avoid short circuit or tie-off, control the engine performance, and prevent the voltage from being too high.

Signs of broken ignition coils: body shake, exhaust pipe shake with abnormal noise, engine shake.

1. The body shakes

In the idle state, the body shakes obviously, in the process of driving, when the speed is below 2500 rpm, the body has obvious shaking, and the acceleration is weak, when the speed exceeds 2500 rpm, the shaking sensation disappears.

2. The exhaust pipe shakes differently

Observing the exhaust pipe mouth, there is a significant intermittent exhaust air flow from the car, and at the same time, the exhaust pipe shakes violently, and the sudden sound can be clearly heard.

3. Engine shaking

Open the engine cover and observe the engine in operation, you can see that the engine has obvious shaking.

What to do if the ignition coil is broken

If only one ignition coil fails, the remaining three cylinders work normally, and it is not a problem to barely drive urgently, but it is very unfavorable to the engine, frame and connecting parts of the car, if there is more than 1 cylinder of the ignition coil is burned, it is more dangerous, and it needs to be stopped immediately for inspection.

Hello dear [smile hungry filial piety] The ignition coil is broken, and the following precursors will appear:1Difficult engine start:

After an ignition coil failure, it may take longer to start the engine when it starts. 2.Engine shake:

Damage to the ignition coil will cause the engine to shake or chatter, which will affect the smoothness of the car. 3.Insufficient acceleration:

If the ignition coil is damaged, the car may not accelerate as fast as it normally would, or even lose power. 4.Engine misfire:

This is one of the most common manifestations of ignition coil failure. When the ignition coil is unable to produce enough voltage, it can cause the engine to misfire or flicker. 5.

Unstable idling: If the ignition coil is damaged, the car may stop or flutter while idling. If you notice any of the above signs, check the ignition coil in time to ensure safe driving.

Hello oh dear, the precursors of a broken ignition coil are as follows: 1. In general, the main symptom of a slight damage to the ignition coil is the weakening of the spark plug jumping spark. 2. Fuel consumption increases, middle limbs increase, and power decreases

With the weakening of the spark plug's ability to skip fire, the combustion of the combustible gas mixture of the engine will be affected, resulting in adverse reactions such as increased fuel consumption and decreased power. 3. A large amount of carbon deposition is generated: due to the weakening of the spark plug jumping ability, it will cause incomplete combustion of the mixed gas of the filial piety school, and the incomplete combustion of the combustible mixed gas will produce a coke substance called carbon deposition, and at the same time, the exhaust pipe of the car will also emit black smoke.

4. Under normal circumstances, there are as many ignition coils as there are cylinders in the engine, and if the ignition coil is seriously damaged at a certain point, resulting in the spark plug spark is not enough to penetrate and ignite the combustible mixture or not jump at all, then the engine will have a lack of cylinders. <>
