Excellent auto ignition coil supplier: Early cars came with one ignition coil. This coil pack was contained in a part called the distributor which was essentially a bundle of wires leading to each spark plug. The distributor was also responsible for timing each fuel ignition and could become de-calibrated over time, causing the engine to run out of sync. Around the 1980s, automakers began installing electronic sensors to handle ignition timing, and multiple ignition coils for better power and efficiency. Nowadays, most engines have an ignition coil placed directly on top of each spark plug. This is known as “coil on plug” configuration. Read extra information at car 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). The quality of Haiyan car ignition coil/ automotive ignition coil is guaranteed.

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.

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.
