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 BAIC EU series is a new energy vehicle under the BAIC Group, which adopts the design of the Senbao D50 and adds blue decorative strips to the front grille and tail emblem for decoration. The BAIC New Energy EU260 continues to use the design of the Senbao D50 in terms of appearance and adds blue decorative strips to the front grille and tail emblem for decoration. In addition, the tail height of the EU260 has been increased by 29mm and the exhaust pipe has been removed. In terms of power, The EU260 is equipped with an electric motor with a maximum power of 100kW, peak torque of 260Nm, and a maximum speed of 140km/h. Official data shows that the vehicle's range can exceed 260km, and can reach 350km under constant speed driving conditions
