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)
After the launch of the BAIC E150, it attracted many people with its stylish appearance. Many people can immediately associate this car with Mercedes Benz because it is so similar to Mercedes Benz B-Class cars. From a neutral perspective, BAIC undoubtedly took a shortcut in entering the sedan industry. As an important partner of BAIC Group, Daimler's help to its brothers at critical moments seems reasonable and reasonable. In fact, it is still possible to find some innovative designs in its appearance compared to the main brand models, which appear more fashionable and have the ability to attract young consumers. However, in the design of subsequent models, it is only fashionable
