Vehicle ignition coil manufacturer and supplier in China

Auto ignition coil wholesale manufacturer in China: Diagnosing a Bad Ignition Coil: Ignition coils typically have a long life of operation — over 100,000 miles. However, they can malfunction eventually, causing that dreaded misfire. This issue will probably start out slowly while being hardly noticeable but will become more problematic over time. When a misfire occurs, even for a few seconds, your engine computer management will likely detect the issue and generate a trouble code. At which point the check engine light comes on. With a diagnostic scanner at a garage or auto parts store, you can then see which cylinder is misfiring and proceed from there. Another sign of a misfire can be a rough engine idle. In extreme cases, the vehicle may feel like it’s surging at a high RPM or like it may stall at low speeds. Other signs that you have a bad ignition coil are worsening gas mileage, sluggish acceleration and a backfiring engine, meaning you hear a loud bang as unburned fuel escapes from the exhaust system.

The car coil itself is a transformer, which is like a transformer in a household appliance. When the voltage changes within a specified range, the transformer will not be burned. Usually, the burning of the transformer occurs when the transformer is overloaded. When solving this problem, we must try to find out the cause of the excessive load or the aging of the components. If there is no fire or weak sparks that suddenly occur during driving, an infrared thermometer or hand touch can be used to determine whether the car coil or the ignition module has an internal short circuit or open circuit fault. When the fault is judged, it can also be restarted. Ignition coil manufacturer has more than 30 years of production experience.

Using a collapsing magnetic field to induce an electric current: When a magnetic field has been created by applying an electric current to a coil of wire, any change in the electric current (increase or decrease in current flow) creates the same change in the magnetic field. If the electric current is switched off, the magnetic field will collapse. The collapsing magnetic field will then induce an electric current into the coil. If an electric current used to create a magnetic field is switched off, the magnetic field collapses, which induces another electric current into the coil.

Using a changing magnetic field to induce an electric current: If a coil of wire is exposed to a magnetic field and the magnetic field then changes (or moves), it creates an electric current in the coil of wire. This process is known as ‘inductance’. This can be demonstrated simply by moving a permanent magnet across a coil. The movement or change in the magnetic field or magnetic flux induces an electric current into the coil wire. There are two main factors that affect how much voltage is induced into the coil: The faster the change (or speed of movement) of the magnetic field and the greater the change in the strength of the magnetic field, the greater the induced voltage. The greater the number of windings in the coil, the greater the induced voltage.
