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)

C4 Picasso introduce

To the C4 derivative car series of Citroen's PSA2 platform, the Big C4 Picasso is different from Sara Picasso's tradition and conservatism in terms of design and element utilization, but more showcases the same sense of future and typical French style as the C4 Dongfeng Citroen Sega. Citroen's family face is still inherited from the Big C4 Picasso, and the large double character chrome logo is very eye-catching. In the design of the lower intake grille, It adopts a brand new C4 inverted trapezoidal style, breaking the dull facial expressions of Sara Picasso and adding a touch of sharpness while being vivid
