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)
The Toyota Vios is a brand new model specially designed by Toyota Motor Company for China. It gathers all of Toyota's latest environmental and safety technologies. As Toyota's first sedan produced domestically in China, the Toyota Vios is characterized by its body shape derived from Toyota's new century design theme, which is extremely dynamic yet powerful; The interior space of the car is exquisite and exquisite, combining high-end design and cutting-edge technology. It is precisely the unity of these characteristics at a high level that has created the Toyota sedan of this new century
