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)

Kia KX7 introduce

The Dongfeng Yueda Kia KX7 was officially launched on March 17, 2017. The car is built on the old Sorento platform and offers 5 and 7 seats to choose from. In terms of appearance, the Kia KX7 adopts a tiger roar style family front face design, with a grid shaped front grille, which is a tough overall shape. The tail lights use LED light sources, and when lit up at night, the display effect will be even better. In terms of body size, the Kia KX7 has a length, width, and height of 4730/1890/1730mm, respectively, And adopt a layout design of three rows and seven seats
