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)

BEIJING-U7 introduce

The super practical storage space of Beijing Automotive Beijing-U7 (formerly known as Beijing Automotive Zhidao U7) has reduced a lot of trouble for travel. The most pleasing aspect of the front storage space is its central armrest box. The two-piece design supports left and right split opening. This design is generally only found in high-end models of Mercedes Benz and BMW, and it is not easy to make the armrest box so innovative at this price point, The space design of this central armrest box is also excellent, with a large depth and strong practicality. In addition, there are two central cup holders in front of the central armrest box, which are just right for storing mineral water. The largest storage compartment in the central control area is located in the area in front of the gear lever, and there are also two USB ports and a 12V power supply. In addition, there is a small storage compartment on the left side of the driver's side, It can be used to store change, bills, and other miscellaneous items. The storage space inside the front glove box and door panel is also large, and the interior of the glove box is treated with flocking, so it is not afraid of scratching valuable items
