How many types of ignition coils are used in automobiles, and what are their respective functions?

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 ignition coil, also known as the high-voltage coil, is used to raise the 12-volt low-voltage electricity in the car to 10,000 volts of high-voltage electricity, transmit it to the spark plug, and ignite the mixture. There are two kinds of ignition coil settings: the first is to place the ignition coil in a certain place in the engine room, and the high-voltage electricity is distributed through the distributor, and then transmitted to the spark plug through the cylinder wire; The second is to place the ignition coil on the upper part of the spark plug, which is directly connected to the spark plug.

This design requires one ignition coil for each cylinder, and four for a four-cylinder engine, which increases the cost but is more efficient. At present, most of the car engines are designed like this.

Ignition coils are divided into two types: open and closed according to the magnetic circuit.

The traditional ignition coil is of open magnetic type, and its iron core is stacked with silicon steel sheets of about millimeters, and the iron 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 coil.

In the car, the ignition coil acts like a transformer, instantly converting a voltage of 12 volts into a voltage of 20,000 or 30,000 volts, and the car needs such a large voltage to operate normally. One thing to pay attention to is the water temperature of the car, and the ignition coil of the car with high water temperature is easy to burn out.

1.The function of the ignition coil is to convert the low-voltage circuit into high-voltage current, supply the spark plug to ignite, and ignite the mixture in the engine cylinder. If the ignition coil fails, the vehicle may not start.

2.The ignition coil is actually equivalent to a transformer. The ignition coil consists of a primary coil, a secondary coil, and an iron core.

It can convert the low-voltage current output of the power supply into high-voltage current, so as to achieve the purpose of ignition. The ignition coil can be divided into two types according to whether there is additional resistance, and can be divided into open magnetic circuit type and closed magnetic circuit type according to the shape of the iron core.

3.As a consumable part in the car, the ignition coil is generally replaced once every 100,000 kilometers. If well maintained, it can last longer.

It is usually possible to open the engine compartment and check the ignition coil accordingly. Such as **, high-pressure nozzle ablation, body shaking, etc. Urgent replacement is required.

The ignition coil is actually a transformer made using the principle of electromagnetic induction, which converts the 6 volt low-voltage current output from the battery or magneto into a high-voltage current of 11,000 to 15,000 volts. The ignition coil is mainly composed of a low-voltage coil also known as a primary coil, a high-voltage coil also known as a secondary coil, and an iron core. The low-voltage coil is wound with thick copper enameled wire, the number of turns is small, one end of the coil is connected to the power supply, and the other end is connected to the circuit switch circuit breaker.

The high-voltage coil is wound with a relatively thin copper enameled wire, and one end of the coil is connected to the spark, and the other end is connected to the body with iron.

The principle of the ignition coil is that after the circuit breaker contact is closed, the low-voltage circuit is connected, and the current passes through the magnetized core of the low-voltage coil, and a magnetic field is generated around the low-voltage coil. When the circuit breaker contacts are normalized by the cam, the low-voltage circuit is cut and the current from the low-voltage coil disappears. At this time, the iron core will reduce the magnetic force, and the magnetic field lines will immediately shrink, cutting the high-voltage coil, so that the high-voltage coil will produce an extremely high voltage induced current.

This high-voltage current is delivered from the high-voltage line to the spark, causing a jump that ignites the flammable mixture of the combustion chamber. On the other hand, if the high-voltage coil is cut magnetically, the low-voltage coil will also be cut, and the low-voltage coil will also produce a magnetic inductance voltage of 200 300V. The direction of this magnetic inductance voltage is the same as that of the original current.

It will hinder the rapid disappearance of the original current, slow down the contraction of the magnetic field, reduce the induced voltage of the high-voltage coil, make the spark unable to ignite, and form a strong spark between the short electrical contacts, so that the contacts burn rapidly. Therefore, in order to eliminate the harmful effect of self-sensing voltage, capacitors are connected in parallel on the low-voltage coil connection. The capacitor plays the role of capacitance and discharge, so when the circuit breaker point is normalized, the capacitor is charged with the self-sensing voltage of the low-voltage coil.

This part of the power is stored by the capacitor and does not form a strong spark on the circuit breaker contacts, protecting the circuit breaker contacts. After the current of the low-voltage coil disappears, the charged capacitor needs to be discharged in the opposite direction through the low-voltage coil and <>

As a result, the original magnetic field also shrinks rapidly, increasing the induced voltage of the high-voltage coil. The low-voltage coil and the high-voltage coil are wrapped around the iron core, and in order to improve the magnetism, a tile-shaped disc is set around the two coils and then placed in the iron case. The iron case has a plastic insulated cover covered with connecting posts that guide the low- and high-voltage coils.

The segment of the high-voltage coil is trapped inside the center, and the terminal is surrounded by a protruding insulating plastic that prevents spark discharge between the high-voltage coil and the low-voltage coil terminals.

The ignition coil is actually a transformer, which uses high-voltage electricity to ignite the flammable compressed gas in the gas cylinder when the car is ignited.

It is a transformer made using the principle of electromagnetic induction, which uses electricity to light the fire, and its structure uses a storage battery and a coil.

The anti-rotation level switch uses a micro motor as the driving device, and the transmission shaft is connected to the clutch. When the material is not in contact, the motor is functioning normally. When the blade touches the material, the motor stops rotating, and the detection device outputs the contact signal, cutting off the power supply to stop rotating.

When the material is lowered, the resistance of the blades disappears and the detection device is restored to its original state by means of a torsion spring.

What is the purpose of an ignition coil? What is the purpose of an ignition coil?

The large and small parts covered in the car, as well as the relationship between them and the working principle, it is estimated that it will be impossible to understand in the past ten days and half a month. It is important to know that the correct ignition time and sufficient ignition voltage of the vehicle are important conditions to ensure the normal operation of the engine, when the basic ignition timing is assembled, the best ignition time under each speed condition is automatically controlled by the ECU, and the ignition voltage is related to the performance of the ignition coil. Let's take a look at what the ignition coil does.

What is the role of an ignition coil – an introduction.

The ignition coil, as the name suggests, is the most critical part of the engine's operation, which powers the ignition step and ignites the compressed fuel mixture. The most obvious feature of the ignition coil failure is the lack of cylinders, there may be a noticeable abrupt sound at idle, and the most obvious feeling is felt on the exhaust pipe by hand, accompanied by severe engine shaking. When the car is driving, the higher the gear, the more obvious the frustration of the car when giving oil, and it is slightly better to give oil smoothly, and the case of heavy oil is the most experienced, and even there is a feeling of turning off the engine, of course, the car itself obviously knows its own problems.

Therefore, convenient car drivers can check the fault in the driving computer**.

The simple explanation of the 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 a transformer responsible for converting the low-voltage current of the vehicle into high-voltage electricity, and under normal circumstances, each cylinder is equipped with a set of ignition coils and spark plugs, and the ignition coils are generally replaced at 100,000 kilometers or even longer.

Proper use of ignition coil method:

The ignition coil is commonly known as the high-voltage pack, which is like a transformer, which converts the electricity of the battery into high voltage, and then the gasoline engine can ignite. Without an ignition coil, the fire will not be ignited.

The ignition coil is actually a transformer, which converts the 12 volts of the car into 2-30,000 volts, and the ignition system of the car uses this high-voltage electricity to ignite the mixture in the gas cylinder.

What is the role of the ignition coil – 5 symptoms.

3.When accelerating, sometimes the power is cut off, resulting in acceleration weakness and shaking.

4.At the same time, when the cylinder is missing, the gasoline and air mixture in the cylinder cannot be ignited and will be discharged from the exhaust pipe. But in fact, the temperature of the exhaust pipe is very high, when the mixed gas reaches the exhaust pipe, it will burn due to the high temperature of the exhaust pipe, and at this time, a large amount of heat generated by combustion will block the three-way catalytic gas hole in the exhaust pipe, resulting in the failure of the three-way catalysis.

5.In addition, if the ignition coil is broken, the engine will vibrate badly, just like a tractor; Give oil, the car is powerless; Shake, the high-end position can't go up; If it is broken, the fault light will be on; The refueling truck sits backwards, then rushes forward, the car is abrupt, the engine shakes when idling, and the exhaust gasoline smell is very strong.

There are also many mysteries waiting for everyone to discover and understand ignition coils, and really know their usefulness. "A good start is half the battle", even if it is a daily drive, a smooth ignition start can make the owner full of confidence in this trip, and all this is built on a good ignition system.

What is the reason why the car runs and grows? It may be a problem with the ignition coil, so hurry up and change it!
