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)

Beiqi Daoda V8 introduce

This new car from BAIC has a fairly good body size, with a length of 4900mm, a width of 1830mm, and a height of 1890mm. It has a wheelbase length of 2900mm, which is better than that of the Alphard. The overall quality of the vehicle is also excellent. Although the front face is almost the same as the old Alphard, it also has its own exciting elements. On the basis of the spindle type air intake, the car is also decorated with the same dot matrix chrome plating as the Alphard. There is no significant difference in brightness and other configurations of the LED circular headlights, Its side adopts a manual sliding door with sliding rails, and the rear end is identical to the old version of the Alphard except for the logo
