Ignition coil 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. See even more details at ignition coil suppliers.
These multiple-coil-pack-systems are much more reliable than the distributors of the past, but individual ignition coils can still fail over time and lead to an engine misfire condition. When a cylinder misfires, that means the fuel inside it is not burning at the correct time or not burning at all. This is also sometimes referred to as a dead cylinder. Prolonged misfiring can lead to larger problems like warped piston rods or corrosion inside the cylinder wall. It can also cause unburned fuel to leak into your exhaust system, which is bad for the environment and worse for your car’s catalytic converters. Once identified, a misfire should be addressed as soon as possible.
To put it simply, the ignition coil is a transformer, which increases the voltage of tens of volts to tens of thousands of volts, but the voltage input to the primary coil is provided by an electronic igniter. The reason why the ignition coil burns out. Ignition coil burnout is mainly caused by the ageing and breakdown of the insulation layer or the damage of the switching transistor. The large gap between the spark plugs will cause the main coil to load, heat, and age quickly. The small gap between the spark plugs will cause the secondary coil to discharge current, heat, and insulation. Fast, the assembled car coil may have a shorter lifespan, such as poor insulation material durability, the large internal resistance of the coil, high heat generation, and low quality of the tertiary tube. Ignition coil manufacturer has more than 30 years of production experience.
By using the effects of mutual inductance and by using a secondary winding that has 100 times more windings than the primary winding, it is therefore possible to transform the original 12-volt supply into a very high voltage. This process of changing a low voltage into a high voltage is referred to as the ‘transformer action’. In an ignition coil, the primary and secondary windings are wrapped around an iron core, which helps concentrate and enhance the strength of the magnetic field and flux, thus making the ignition coil more efficient.
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.
