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)

Dongfeng Yufeng introduce

On June 19, 2012, Dongfeng Yufeng Commercial Vehicle, a subsidiary of Dongfeng Motor, was officially launched. In recent years, with the diversification of European light passenger vehicle models, it has gradually changed the dominant position of Japanese light passenger vehicles in the market share. European light passenger vehicles, with their various characteristics in body size and power, can fully meet the diversified customer needs of passenger transportation, freight transportation, business reception, etc. Dongfeng's launch of this Yufeng high-end commercial MPV, I hope to establish a foothold in this fiercely competitive niche market by leveraging the product's own advantages
