ignition coil introduce

With the development of gasoline engines in automobiles towards high speed, high compression ratio, high power, low fuel consumption, and low emissions, traditional ignition devices are no longer suitable for use. The core components of ignition devices are ignition coils and switch devices. By increasing the energy of the ignition coils, the spark plug can generate sufficient energy to produce sparks, This is the basic condition for the ignition device to adapt to the operation of modern engines. The ignition coil is divided into two types according to the magnetic circuit: open magnetic and closed magnetic. The traditional ignition coil is used with an open magnetic type, and its iron core is stacked with about 0.3 millimeters of silicon steel, with secondary and primary coils wound around the iron core. The closed magnetic type uses an iron core similar to III to wrap around the primary coil, and then wraps around the secondary coil outside. The magnetic field line is composed of an iron core to form a closed magnetic circuit. The advantage of the closed magnetic ignition coil is that it has less magnetic leakage, Due to its small energy loss and volume, electronic ignition systems generally use closed field ignition coils)

Toyota Yizhi introduce

The Yizhi has a stylish and atmospheric appearance, and the overall full visual effect gives a strong visual impact. While inheriting Toyota's excellent lineage, there are also innovative elements in the appearance. The bony lines protruding from the front cover and side are used as embellishments. The lower grille adopts a honeycomb design, with a more prominent grid. The fog lights on both sides are also oriented towards the center position by the lines. The front of the vehicle highlights Toyota's classic style, which is fashionable and agile while maintaining a generous and stable appearance
