Is the ignition coil only used when starting the engine?

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 generator will be used all the time after it starts, otherwise it will go out; Generally, the car has an ignition coil, and the distributor distributes the high-voltage current to the spark plugs of each cylinder.

The ignition coil is to change the low-voltage direct current of 12V into a high-voltage direct current of about 15000V. For ignition of gasoline engines (i.e., for normal operation, including starting and normal ignition).The distributor is assigned to the spark plug of each cylinder according to the working order of each cylinder.

As long as the ignition lock is opened, the ignition coil will be energized, and only when the crankshaft rotates, there will be high-voltage electric ginseng.

One engine has only one ignition coil.

It is a high-voltage package, and the function is that the transformer transforms the low-voltage into high-voltage, and then the distributor distributes the high-voltage electricity to each cylinder on time according to the information provided by the ignition cam to ensure on-time ignition.

One car configuration one is reasonable.

The ignition coil is an important device in the engine ignition system, which is connected to the power supply system (such as batteries, generators) at one end and the ignition device (such as spark plugs) at the other end. The ignition coil is always in operation, both during engine start-up and operation, and is used to supply the ignition electrical pulse to the ignition device.

Strictly speaking, there is no correspondence between the ignition coil and the number of cylinders, but it is related to the spark plug, but most vehicles have a correspondence between the spark plug and the cylinder to map to the proportional relationship between the ignition coil and the cylinder. Common combinations are 1:1 and 1:

2. On four-cylinder vehicles, it is common to see a coil with 2 spark plugs. The distributor is used for ignition sequencing and switching between different spark plugs.

No, it changes with the working condition of the engine, the engine cylinder has 4 working conditions, namely air intake, compression, work and exhaust, the ignition coil in a cycle is ignited once, the engine keeps circulating, and the ignition coil is constantly ignition.

No. It works as the compression stroke of the engine reaches the end of every four strokes.

When the gasoline engine starts, the generator generates power normally, the wiring is normal, and there can be no battery. You must know that there are actually two power supplies on the car: one is the battery; One is a generator.

The engine must have oil and points if it wants to work, each cylinder has an ignition coil, air intake, compression, work (ignition), exhaust, this four-stroke is a working cycle, a working cycle crankshaft rotates twice, repeat the above cycle, and the engine runs.

Power on first, then fire. Let the oil pump start to work, and provide the car with oil pressure in advance, so as to facilitate the smooth start of the engine.

When the car starts, the computer module has a self-test process, open the ignition key, each computer module will send a signal to the sensor, and the sensor will give the computer module a feedback message, proving that the sensor can work normally, and the communication of each line is also smooth.

At this time, the phenomenon seen on the instrument is that all the fault lights are lit, and the pointers on the instrument of some cars will also swing around.

If everything is normal after the self-test, the fault light will be extinguished, and if an abnormality is found, then the fault light will always be on, and it will also be on after the fire, the purpose is to prompt the driver to go for maintenance.

Extended Material: Considerations.

1. Maintenance of automobile engine.

The engine of the car should be cleaned at the right time. Because prolonged use will form a thick layer of carbon deposits on the surface of the engine.

As a result, the rubber parts in the engine are subject to greater corrosion.

Second, gasoline and water are both.

To prevent evaporation.

In summer, the temperature is generally high. So both gasoline and water evaporate more easily than usual. Because the water tank and fuel tank should be checked frequently, and when the gasoline and water are relatively small, they should be added in time.

3. Pay attention to hygiene inside the car.

Summer is the season when bacteria grow the fastest, so keep the interior of your car clean, especially car seat cushions, car steering wheel covers, and car floor mats that are prone to dirt.

Fourth, the car wiper should be replaced.

When driving in rainy days, you must pay attention to whether the wipers are good, the eraser leaves on the wipers for a long time will age, in order to drive in rainy days to have a better driving sight, the car wipers are best replaced once in one to two years.

Fifth, the car mat should be updated.

A good car mat is an important choice for car sun protection in the hot season. Choose a mat that is cool and not too slippery. In order to avoid traffic accidents caused by body sliding while driving.

Sixth, the car body should also be maintained.

Ultraviolet. The damage to the car is also great, such as the penetration effect on the car paint.

You may notice that after a long period of sunlight exposure to a white car, the color of the body becomes significantly lighter and yellower.

Therefore, in the summer, it is necessary to wax and glaze the car.

It can play a role in protecting your car.

Let the car be powered on for self-test first, and then start the car after the self-test is completed, but now there are more models that start with one button, and they are generally started directly.

After the car is turned off, not only the oil will slowly fall, but the fuel will also be like this, at this time, the oil pressure in the oil circuit will drop, and when the car self-inspection car is energized, the fuel pump will instantly supply oil to the oil circuit, and reach a certain oil pressure under the detection of the oil pressure sensor. The purpose of this is to be able to start the engine smoothly.

Requirements for automotive ignition systems.

1. It can generate a voltage sufficient to break through the spark plug gap.

The voltage required for the spark plug electrode to break down and generate a spark is called the breakdown voltage. The secondary voltage generated by the ignition system must be higher than the breakdown voltage in order for the spark plug to skip fire.

2. The spark should have enough energy.

When the engine is working normally, only 1 5 mJ of spark energy is required because the temperature at the end of the mixture compression is close to its autoignition temperature. However, when the mixture is too thick or too thin, when the engine starts, idles or opens the throttle sharply, a high spark energy is required.

3. The ignition time should be adapted to the working condition of the engine.

First of all, the ignition system should be ignited in the order in which the engines work. Secondly, ignition must be carried out at the most favorable moment.

Power on first, let the oil pump start working, and provide an oil pressure to the car in advance, so as to facilitate the smooth start of the engine.

The fuel pump is started after the power is turned on, which refers to the fuel pump.

After the car is turned off, not only the oil will slowly fall, but the fuel will also be like this, at this time, the oil pressure in the oil circuit will drop (here mainly refers to the long stop, the short stop does not have the problem of oil pressure reduction), and when the car self-test car is energized, the fuel pump will instantly supply oil to the oil circuit, and reach a certain oil pressure under the detection of the oil pressure sensor.

The purpose of this is to be able to start the engine smoothly, and the owner of the car during the car self-inspection, if you listen carefully, you can also hear the sound of the oil pump pressurization from the chassis of the car, and if your car is well insulated, it may not be heard.

When the car starts, it is powered on first and then ignited.

1. First turn on the electric oil pump relay to start supplying oil to the engine, airbag self-test, engine fault lamp self-test, oil lamp self-test, water temperature self-test lamp.

2. It can be easily ignited after the self-test is over.

If it is ignited directly, it is easy to cause difficulty in starting, because the oil pump does not start working.
