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)

China is ushering in a new wave of urbanization, with an unprecedented increase in demand for urban logistics. However, there is a sharp conflict between current urban logistics and modern urban management. On the one hand, the volume of urban logistics is constantly increasing, and the demand for logistics vehicles is growing. On the other hand, due to considerations of urban image and management, the ban on freight vehicles in the main urban areas of major and medium-sized cities is also increasing, Causing difficulties for the most suitable heavy-duty trucks, light trucks, and pickup trucks to enter the city, and mini vans that could have been replaced are also being replaced by big cities“
