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)

The highly anticipated Volkswagen's first domestically produced SUV, the Tiguan, received reliable news in February 2010 and will announce its price on March 26, 2010. This compact SUV first met consumers at the 2009 Guangzhou Auto Show and gained widespread attention and love upon its appearance. The appearance of the Tiguan broke the awkward situation of German cars without domestically produced SUV products, At the same time, it also provides consumers with more and better choices. Currently, the Tiguan has been exhibited at Volkswagen 4S stores in Shanghai, Beijing, for consumers to further understand. Volkswagen Tiguan is equipped with a variety of safety features this time, and the entire series is equipped with an ESP body stability system as standard EBD electronic brake force distribution and ASR traction control, such as some rare EDS electronic differential locks The EPB electronic handbrake, automatic parking function, and TPR tire pressure monitoring system have all become standard features of the Tiguan, indicating that Volkswagen attaches great importance to safety. The front double airbags and front side airbags can ensure the driving safety of passengers, and the standard child lock also values the safety of children. In short, the Tiguan's sincerity in safety configuration is enough to impress the Chinese people
