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)

桑塔那 introduce

In the late 1990s, Shanghai Volkswagen Co., Ltd. developed the "Shanghai Santana 2000" sedan, aiming to sprint towards the 21st century and challenge the future, sparking a "new Santana" whirlwind on the coast of the East China Sea in China The Santana brand has been deeply rooted in people's hearts in China for 20 years, but unfortunately, shopping malls are like battlefields. The current automotive market is full of gunpowder. The Santana 2000 was discontinued on January 31, 2004, and the replacement model, the Transcender (Santana 3000), was officially produced on February 1, 2004. Shanghai Dazhong claimed that the title of the "Transcender" of the Santana 3000 model is called "Modern Classic Car", which means "Modern Technology. Classic Model", On the one hand, it is because the Santana has become a classic model, and the "Transcender" continues the brand spirit of the Santana; On the other hand, the Transcender also adopts relatively advanced technologies, such as variable frequency air conditioning
