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)

POLO introduce

Volkswagen POLO (Polo). As two new A0 class sedans launched by Shanghai Volkswagen this year, the Polo is one of the two masterpieces launched by the Shanghai Volkswagen design team after successfully designing the PASSAT leadership. The Polo is a two door model developed in sync with the German Volkswagen POLOGP based on the unique aesthetic needs of the Chinese market, The POLO is a three box model independently designed and developed by the Shanghai Volkswagen design team. The Volkswagen POLO (Polo) is another masterpiece developed simultaneously by the Shanghai Volkswagen development team and Wolfsburg, Germany In 2003, when the POLO GP project in Wolfsburg, Germany was launched, the design team of Shanghai Volkswagen also began to brainstorm new POLO projects for the Chinese market and participated in discussions on the basic development plan for the new generation of POLO
