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)

BAIC Weiwang 407EV New Energy introduce

In terms of appearance, although this car is a pure electric box truck, its appearance tends to be designed in the style of a concept car. Because it does not need to collide with the wind and dissipate heat like an oil burning motor vehicle, the front face of the car only uses a banner style black paint decorative panel, which is integrated with daytime running lights, making the entire truck look full of texture. Although the rear end is relatively square, the rich line design gives the rear end a certain sense of hierarchy, The rectangular tail lights with a vertical bar style are also very stylish, and the lighting effect is stunning. According to the vehicle positioning, the Weiwang 407EV can not only enter through the rear door in crowded streets, but also through the sliding door on the right side. The tail door adopts a 4/6 ratio split design, making it more convenient and flexible to get off and transport goods. The entire trunk volume of the car is 4.5 cubic meters, and the load capacity can reach 810kg
