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 A9 introduce

The Dongfeng A9 and Citroen's all-new C6 are built on the same platform, but in terms of appearance, the new car looks calm and atmospheric, and adopts a family style design with "Qian Gua" elements. The headlights and grille on both sides are connected, and LED light sources are also used inside. On April 12, 2016, the Dongfeng A9 was officially launched, with a price range of 179700 to 219700 yuan. According to Sina Auto News, we recently learned from relevant channels that the pre-sale price range of the new mid to large sized Dongfeng A9 under Dongfeng Fengshen is 179700 to 229700 yuan. Based on this latest news, we also contacted the Dongfeng Fengshen 4S store, who said that the pre-sale price of the car is currently announced to the public. From 170000 to 220000 yuan, it can be seen that the pre-sale price of 179700 to 229700 yuan is still quite informative. It is reported that the Dongfeng A9 will be officially launched on April 12, 2016
