Ignition coil wholesale manufacturer by hj-auto.com: How does an ignition coil work? The main task of the ignition coil is to transform the on-board voltage of 12V available in the vehicle to the required ignition voltage and then passed on to the spark plug. Basically, the function of the ignition coil is relatively simple to explain. The ignition coil itself contains a primary and a secondary winding. The primary winding has very few turns, while the secondary winding has very many. As soon as the engine control unit sends a signal to the ignition coil, the on-board voltage of 12V flows through the primary winding. Through this process, a magnetic field is built up. As soon as the signal from the engine control unit is interrupted again, this magnetic field is abruptly reduced. This abrupt degradation generates a high voltage in the secondary winding. This high voltage is now transmitted to the spark plug, which consequently generates a spark. Discover more details on auto 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.
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.
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.
