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)

The popular S500 introduce

The Fengxing S500 is Dongfeng Fengxing's first all-around family 7-seater MPV, launched in 2015. It was officially unveiled at the Shanghai Auto Show in April 2015. With Fengxing's 15 years of deep cultivation in the MPV market, the Fengxing S500 breaks through traditional thinking and takes the lead in proposing the idea that "MPVs can also become the first family car" in the market, overturning the inertia of "consumers only buy MPVs when they buy the second car" in the market The S500 fully matches the purchasing needs of the "first car" in terms of exterior and interior design, spatial layout, configuration level, and power experience, creating the first choice for families to purchase. The 2019 Fengxing S500 has launched four models (new practical models), all equipped with 1.5L engines, with a price range of 59900 to 70900 yuan
