According to the magnetic circuit, the ignition coil is divided into two types: open magnetic type and closed magnetic type.
Open magnetic circuit ignition coil
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 secondary coil is an enameled wire with a wire diameter of 0.05 to 1 mm, and the number of turns is 20,000 to 30,000. The wire diameter of the primary coil is 0.5 to 1.0 mm, which is thicker than the secondary coil, and the number of turns is only 150 to 300. 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 winding directions of the primary coil and the secondary coil are the same. The start of the secondary coil is connected to the high-voltage output connector, and the end of the secondary coil is connected to the start of the primary coil and connected to the "+" terminal of the housing. The end of the primary coil is connected to the housing. The "one" post is connected to the collector of the power transistor in the igniter, and the igniter controls the on and off of the primary coil current.
Closed magnetic circuit ignition coil
The iron core of the closed magnetic circuit ignition coil is closed. 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. Magnetic flux, the primary coil must have a large 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, open magnetic circuit ignition Miniaturization of the coil is impossible. On the contrary, the closed magnetic circuit ignition coil, due to its low magnetic resistance, can effectively reduce the magnetomotive force of the coil and miniaturize the ignition coil. 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 combustible compressed gas in the cylinder is ignited by the spark plug. The traditional ignition coil is an open magnetic type, and its iron core is laminated with silicon steel sheets of about 0.3 mm, and the iron core is wound with secondary and primary coils. The closed magnetic type uses an iron core shaped like III to wind the primary coil, and then the secondary coil is wound outside. The magnetic line of force is formed by the iron core to form a closed magnetic circuit. The advantages of closed magnetic ignition coils are less magnetic leakage, low energy loss, and small size. Therefore, closed magnetic ignition coils are commonly used in electronic ignition systems.
