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 a6 introduce

The Audi A6L is a series of cars developed by FAW Volkswagen Audi based on the new A6 in Germany. It is a successor to the A6 and was launched on June 16, 2005 In June 2012, Audi's new generation A6L was launched, equipped with 35 TFSI power, and its appearance seemed a bit like the all-new A4L version. On January 23, 2014, the new generation A6L was launched, priced at 38300-742600 yuan, which is almost no different from the 2012 model. For a long time, the official image of Audi A6 has been deeply rooted in people's hearts, and even in Europe and America, A6 has also been favored by government agencies and business people. The 09 A6L has made some modifications in terms of appearance, The biggest change is the addition of LED daytime running lights to the headlights, and the use of LED tail lights with a new arrow shaped design. In March 2012, the younger generation of Audi A6L was launched in China
