Problems after changing the high voltage ignition wire of the car

It has nothing to do with the force cool line, the dry winding wave is caused by the spark plug without resistance, if your spark plug model has r, it means that the spark plug has resistance, and there will be no interference wave affecting the car's electrical appliances. It will not burn the ignition coil, because the voltage output of the ignition coil is adjusted at the factory and is in line with the parameters, so it will not damage the higher-level high-voltage line and spark plug. If you change the high-level ignition coil and do not replace the high-voltage wire and spark plug, then the high voltage output of the ignition coil will destroy the low-level high-voltage wire and spark plug.

As for whether it will increase fuel consumption, only changing the high-voltage line will not play a role, but it will not cost more fuel than not changing it. If you want to achieve fuel economy and improve power, you must replace the spark plug with a relatively high ignition rate, and the high-voltage wire that can fully transmit high voltage and high current and the ignition coil that can output high voltage. It can also be used to ensure that the high-voltage wire and spark plug are replaced, and the advance angle of the ignition coil can be appropriately adjusted.

But the disadvantage is that the emission standards may not meet the standard, and there will be some problems during the annual inspection of the vehicle.

Where to start? There will be radiated interference only if there is resistance or contact is not enough! Even if it does, it will not interfere with the water temperature sensor. Burn the ignition coil!

The impact of the aging of the slip coil of the high-voltage ignition hole on the car is as follows:

1. In the idle state, the body shakes obviously. Observing the exhaust pipe mouth, the exhaust gas flow of the Nasola car has obvious intermittent movements, and at the same time, the exhaust pipe shakes violently, and the sound of "sudden" can be clearly heard;

2. In the process of driving, when the speed is below 2500 rpm, the body shakes significantly and the acceleration is weak; When the speed exceeds 2500 rpm, the jitter disappears;

3. Open the engine cover, observe the engine in operation, and find that the engine has obvious shaking, which is obviously not the jitter under normal engine working conditions, and the jitter amplitude is very large.

The performance of the high-voltage package of the ignition coil of the car is broken: 1. Engine shaking: with the damage of the high-voltage package of the car, the engine is very prone to cylinder shortage, and once the engine is missing, the pants will shake violently in the process of operation; 2. The balance consumption of oil cleaning increases and the power decreases

Even if the damage to the high-pressure bag of the car does not cause the engine to be short of cylinders, it will still affect the normal flashover of the spark plug; 3. A large amount of carbon deposition is generated: when the spark plug jumping is affected, the combustible mixed gas will easily cause incomplete combustion, and the incompletely burned combustible mixed gas will produce a coke substance called carbon deposition, and the automobile exhaust will also emit black smoke.

The main reasons:

1. Under the spark plug inspection, the use time should not be too long, the gap should not be too large, and replace it with a new one if necessary.

2.The high-voltage wire should be purchased with a high-pressure and high-temperature resistant wire that meets the standard, and the plug contact with the ignition coil should be matched appropriately.

3.The ignition coil ensures that there is no breakdown and channeling.

How the ignition coil works:

The reason why the ignition coil can turn the low-voltage electricity on the car into a high-voltage voltage is because it has the same form as the ordinary transformer, and the ratio of turns between 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.

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.

1. Check whether there is a 12 volt voltage on the black wire on the ignition coil 2 Check whether the ignition black wire has a 12 volt power supply, whether the brown and white wire is well grounded 3 Check the voltage of the red and black wire on the distributor plug marked + on the socket, there should be 5 volt voltage, there is no check ignition and related lines 4 The green and white wire on the socket marked with 0 on the distributor plug is intermittently struck with a wire, if there is a high-voltage spark on the high-voltage line of the ignition coil, there may be a problem with the distributor, replace it, if not, Check the ignition and the ignition coil 5 will be on the green wire of the ignition with a wire intermittent iron, the ignition coil high-voltage line should have a weak high-voltage flashover, no ignition coil is changed, if there is, change the ignition.

(1) Common faults of low-voltage circuits: insufficient battery storage; Poor or deranged wire connections; Poor battery tie-up; Damage to the distributor or Hall sensor; Damaged ignition switch or poor wiring; The transistor ignition control unit is damaged or poorly wired. Most of the diagnostic methods for low-voltage circuit faults use ammeter or voltmeter to check the fault line by line to eliminate the fault point.

2) Common faults of high-voltage circuits: high-voltage lines fall off or leakage; Breakage and breakdown of distributor cover; Ablation, rupture, breakdown of distributor fire head; The spark plug electrode gap is too large or too small; Excessive carbon deposits in the spark plug; damage to the spark plug insulator; The ignition coil is damaged or the wiring is falling off. Most of the faults of high-voltage circuits adopt the high-voltage fire test method, that is, the high-voltage line in the center of the distributor or the high-voltage line of a cylinder is unplugged, and the wire head is placed at a distance of 3-6mm from the cylinder block, and the engine is started to test the fire, as shown in Figure 2.

If there is a spark and the spark is strong, it means that the ignition system is working properly.
