Quality car ignition coil manufacturer and supplier: Apart from the coils, another likely culprit for misfiring is the neighboring spark plug, faulty spark plug wires or a larger electrical issue. When you take your car to a professional shop, they have an array of voltage testing equipment to see where the malfunction is happening along the circuit. They may also look for other things like clogged fuel injectors. Once you’ve identified a faulty ignition coil, replacing them usually costs about $250 per part. Then there’s labor on top of that, which can easily add an extra $50 or more per coil. If you’re handy, this is a job you may want to attempt yourself since the ignition coils are usually located in an accessible spot on top of the engine and can be removed with a basic socket wrench. Just detach the 12V battery first to be safe. Read additional details at wholesale ignition coil.
Principle of the ignition coil: It is composed of the main coil, a secondary coil, a magnetic core, a switching transistor and other auxiliary components. The main coil is charged by a battery, and the secondary coil is discharged by a spark plug to ignite, and the triode is responsible for switching. The charging time is controlled by the battery voltage and the engine speed to ensure that the energy is consistent each time. The ignition coil has two types: 3-wire and 4-wire. The 3-wire is the power supply positive, negative, switch control (ECU command), and the 4-wire has one more ignition detection. Wire can detect whether the spark plug is ignited (whether there is discharge current in the secondary coil). Haiyan ignition coil manufacturer has many offices in other countries. One of the larger productive enterprises.
For ignition coils (and many types of electrical transformer), the secondary winding is made with more windings than the primary winding. When the magnetic field collapses, it will therefore induce a higher voltage into the secondary winding than into the primary winding. Here, the secondary winding has more coils than the primary winding. When the magnetic field collapses, the voltage in the secondary coil will be greater than the voltage induced in the primary winding.
All ignition systems for modern petrol engines use ignition coils for the same basic function: to create the high voltage required to produce a spark at the spark plug. Aftermarket professionals will be familiar with their purpose and basic attributes – but they may not know about the in-depth scientific principles they rely on. Here, we explain how electromagnetism is at the heart of an ignition coil’s essential role… Although ignition systems have certainly evolved over time – in particular incorporating more and more electronics – they still bear the hallmarks of the original coil ignition systems that were introduced more than 100 years ago.

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.
