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)

Peugeot 207 hatchback introduce

The Peugeot 207 is developed on the basis of the Peugeot 206 platform, with no fundamental changes in the body frame. Its biggest difference from the replaced Peugeot 206 lies in the front and rear of the car. The new headlights and grille are not only beautiful, but also very agile, which are the biggest highlights in the appearance. French Peugeot cars have always been known for excellent handling quality, with a very solid chassis. Its excellent handling quality can meet the young generation who pursue driving pleasure
