Top 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 even more information at wholesale ignition coil.

The automotive ignition coil consists of an electrically-conductive wire wound into a helix, usually around a magnetic core. When power is applied across the two coils, it produces an electrical field that generates an electromagnetic field that induces currents in the secondary winding of the coil. This high voltage is then stepped down by one or more stages before being applied to the spark plug. There are three different types of car ignition coils: Single-coil systems use one coil per cylinder. Dual-coil systems use one coil per cylinder, but they are wired in series so that each fires twice for every cycle of the power supply. In this way, it’s possible for both coils to fire at once, improving efficiency and reducing wear on the engine by giving it more time between firings.

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. Haiyan ignition coil manufacturer has many offices in other countries. One of the larger productive enterprises.

The primary winding of an ignition coil will typically contain 150 to 300 turns of wire; the secondary winding will typically contain 15,000 to 30,000 turns of wire, or around 100 times more than the primary winding. The magnetic field is initially created when the vehicle’s electrical system applies approximately 12 volts to the ignition coil’s primary winding. When a spark is required at a spark plug, the ignition system will switch off the current flow to the primary winding, which will cause the magnetic field to collapse. The collapsing magnetic field will induce a voltage into the primary winding in the region of 200 volts; but the voltage induced into the secondary winding will be approximately 100 times greater, around 20,000 volts.

The first coil-based ignition system is credited to the American inventor Charles Kettering, who developed a coil ignition system for a major vehicle manufacturer around 1910/1911. For the first time, he devised an electrical system that powered the starter motor and ignition at the same time. The battery, a generator and a more complete vehicle electrical system provided a relatively stable electrical supply to the ignition coil. The Kettering system used a single ignition coil to produce a high voltage, which was passed to a rotor arm that effectively pointed the voltage to a series of electrical contacts located in the distributor assembly (one contact for each cylinder). These contacts were then connected by spark plug wires to the spark plugs in a sequence that made it possible to distribute the high voltage to the spark plugs in the correct cylinder firing order.
