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 Fengshen AX7 New Energy introduce

The Dongfeng Fengshen AX7 new energy is currently a compact SUV under the Dongfeng passenger car manufacturer that has not been launched. It is an independent vehicle. For consumers, the advantage of purchasing a high resale value model is that its price is not significantly affected by the price reduction trend, It can also help us consumers bear relatively small economic losses caused by product depreciation. The resale value of Dongfeng Fengshen AX7 new energy vehicles is an important indicator for consumers to judge cost-effectiveness before purchasing a car. The so-called resale value refers to the ratio of the selling price of a certain model to the previous purchase price after using it for a period of time, It depends on multiple factors such as the performance, price fluctuation, reliability, accessory prices, and maintenance convenience of the car, and is a reflection of the overall level of the car
