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)
As the first urban SUV of the Peugeot brand, the Peugeot 4008 follows the Peugeot HR1 concept car design concept. The Peugeot 4008 integrates the design styles of family hardtop sports cars and urban SUVs, presenting a distinct and harmonious style taste and modern beauty. The Lion Roar front face is Peugeot's design label that continues for a century, with the difference being the reduced intake grille and more prominent chrome decoration, At the same time, the more personalized design of the floating intake grille with a feline style enhances the sense of fashion and technology
