Ignition coil is a kind of transformer that generates high-voltage electricity required for ignition. Generally, the ignition coil used in the ignition system of an engine is distinguished by a magnetic circuit, which can be divided into two types: open magnetic circuit and closed magnetic circuit. The open magnetic circuit ignition coil is generally a pot-shaped structure. It is composed of several silicon steel sheets to form a rod-shaped iron core, and the secondary coil and the primary coil are respectively wound on the outside of the iron core. The primary coil is wound on the outside of the secondary coil, so the magnetic flux change produced by the secondary coil is exactly the same as that of the primary coil. The iron core of the closed magnetic circuit ignition coil is closed, and all the magnetic flux passes through the iron core. The magnetic permeability of the iron core is about 10,000 times that of air. Therefore, the open magnetic circuit ignition coil wants to obtain the same as the closed magnetic circuit ignition coil If the magnetic flux is higher, the primary coil must have a larger magnetomotive force (ampere turns). Therefore, a primary coil with a larger number of turns and a larger wire diameter must be used; the primary coil has a large number of turns. If you want to obtain the same turns ratio, the number of turns of the secondary coil must also be increased. Therefore, a closed magnetic circuit ignition coil The ignition coil can be miniaturized. At present, the closed magnetic circuit ignition coil has been quite miniaturized, and can be combined with an igniter or even integrated with a spark plug.
The function of the ignition module is equivalent to an electronic switch. It controls the current in the primary winding of the ignition coil. This conversion function induces the high voltage in the secondary winding of the ignition coil that is directly ignited by the spark plug through the rotor and the secondary wire. The ignition module controls the ignition coil to perform in-cylinder ignition by receiving a signal when the vehicle is started. If there is a problem with the ignition module, the engine may stall and the vehicle cannot be started.
