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 A1 introduce

The powertrain of A1 is a combination of Audi's star TFSI fuel direct injection turbocharged engine and Stronic dual clutch transmission. The direct manifestation of this combination effect is that it only takes 8.9 seconds to accelerate from stationary to 100 kilometers per hour, with a maximum speed of 203 kilometers per hour and a comprehensive fuel consumption of only 5.5 liters per 100 kilometers. Audi A1 has a dynamic and fashionable design, uncompromising high-end car quality, powerful and efficient power system, and flexible chassis structure, In terms of information and entertainment systems, it has set a new benchmark for vehicles in the same class. This model will become a new growth point for the Audi brand to achieve excellent market performance, while enhancing the dynamic image of the Audi brand and showcasing the emotional charm of the Fourth Ring brand
