Does the ignition coils for car affect power?
Car high voltage ignition coil is composed of main coil, secondary coil, magnetic core, switch triode and other auxiliary components. The main coil is charged by the battery, the secondary coil discharges the spark plug to ignite, 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. There are two types of ignition coils: 3-wire and 4-wire. The 3-wire is positive and negative for the power supply. Switch control (ECU command), 4-wire has an additional ignition detection The wire can detect whether the ignition coil with spark plug is ignited and whether there is a discharge current in the secondary coil.
high voltage transformer with ignition coils , 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 igniter.
Cause of ignition coils for car burn out:
It is mainly due to the aging breakdown of the insulating layer or the damage of the switch triode. The gap between the spark plugs will lead to a large load on the main coil, the heat will be large, and the insulating layer will age quickly. The small spark plug gap will lead to a large discharge current of the secondary coil. The ignition coil may have poor durability of insulating materials, large internal resistance of the coil, and rapid heating, and the life of the triode will be shorter if the quality of the triode is not high.
If it is always burned out, will it burn out soon after replacement and why?
①Look at the problem of the generator first. If the power generation is too high, the ignition coil will be easily burned out if the load is too heavy. However, if the power generation is too high, the body electrical appliances, such as light bulbs, will often be damaged; of course not To rule out the quality problem of accessories, it is best to measure the power generation first.
②The spark plug gap is too large, adjust the gap or replace the spark plug.
③ If the gasoline quality is not good, try changing the gasoline with a higher grade.
④The cylinder compression ratio is wrong, adjust the compression ratio.
⑤ If there is a program failure on the computer version, you can go to the repair shop to use the computer to check the car and clear the wrong information. If it still doesn't work, there may be a problem with your car's transmission.
⑥ Power supply voltage is unstable.
⑦ High voltage resistance is abnormal, replace the high voltage line.
⑧ Secondary short circuit phenomenon.
⑨ Ignition coil overheating due to high primary current of ignition controller.
⑩ It is difficult to work under high temperature and high pressure waves.
(11) There is a small chance that the coil itself is the problem, you can change the brand to try.
(12) Ignition unit works badly.
