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 first SUV model of Changhe, Q25, will be officially launched on March 28, 2016. Previously, Changhe Automobile had announced that the pre-sale price of the car was 55900 to 76900 yuan. It is positioned as a small SUV model on the same platform as the BAIC Shenbao X25, but the exterior adopts the unique design language of the Changhe family; The new car will offer 7 paint options for consumers to choose from, including dazzling white, cool gray, casual blue, dreamy gold, passion orange, magic brown, and seductive red; The interior of the X25 is almost the same as that of the X25 except for the logo. The new car's center console is wrapped with carbon fiber texture material, and the top of the center console is equipped with an independent 7-inch LCD screen; Based on the previous test drive experience of the Senbao X25, the mobile intelligent interconnection system has a relatively flexible operation and fast screen feedback, which is considered excellent among its peers;
