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)

Pentium B90 introduce

The interior center console design of the B90 is stable and atmospheric, clearly leaning towards a business style, and also has a strong atmosphere of Japanese luxury models, which is consistent with its positioning as a business vehicle. However, the deep top and light bottom interior color scheme is also more in line with the needs of family use. The tail shape of the B90 is less sharp than the front, conveying more stability. However, from the details, the fashionable design of the B90 can still be seen, By using the corners at the top of the trunk, a more dynamic small crease is created. The LED light source equipped with the tail lights can provide a safer effect at night and add a touch of fashion to the B90
