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)

Audi A5 introduce

As a brand new series within the Audi family, positioned in the passionate segment of high-end two door sports cars, this is a charming car series that combines Audi's usual dynamic design, exciting power and handling performance, and excellent manufacturing technology. It is a new interpretation of Audi's brand concept of "breaking through technology and inspiring the future" The A5 and S5 were ordered in Europe on March 6, 2007, with the first batch of finished products expected to be delivered to users in June. On the Audi A5, many design elements of the 2003 Audi Nuvolari quattro concept car can be seen (the Nuvolari quattro concept car is named after one of the greatest drivers in Audi racing history, Tagio Nuvolari, who won the European GP Grand Prix multiple times by driving the Four Ring Silver Arrow race in the 1930s), Let people feel for the first time Audi's pursuit of strong power, professional design, and high-performance potential sports cars - a bold step towards the future
