High quality vehicle ignition coil wholesale supplier: Gasoline vehicles are usually powered by a simple 12-volt DC battery. This is enough voltage to engage a starter motor and get the engine turning, but it’s not enough for actual combustion. (A spark plug needs around 40,000 volts for combustion.) That’s where the ignition coil comes in. It contains a step-up transformer (also known as a coil pack) to convert that tiny current into quick bursts of several thousand volts at a time. This electricity is then sent to each spark plug in perfect time with the cylinder’s combustion cycle, igniting fuel vapor with oxygen and producing power. Diesel engines notably lack ignition coils because they ignite their fuel using heat and pressure alone. Read more info at ignition coil suppliers.

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.

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). Ignition coil manufacturer has more than 30 years of production experience.

In the same way that increasing the speed of movement of a magnetic field across a coil of wire will increase the voltage induced into the coil, if a collapsing magnetic field can be made to collapse more rapidly, this will induce a higher voltage. Additionally, a higher voltage can also be induced into the coil if the number of windings in the coil is increased. Mutual inductance and transformer action: If two coils of wire are placed next to or around each other and an electric current is used to create a magnetic field around one coil (which we call the primary winding), the magnetic field will also surround the second coil (or secondary winding). When the electric current is switched off and the magnetic field then collapses, it will induce a voltage into both the primary and the secondary windings.

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.
