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 Q3 introduce

The Audi Q3 is a brand new compact SUV, or you can also consider it a Crossover crossover car. This is the second model in the market to adopt a similar positioning after the BMW X1. Whether in terms of overall vehicle design or power configuration, the Audi Q3 performs exceptionally well. The Audi Q3 is based on the same PQ35 platform as the Volkswagen Tiguan, and is positioned below the Q7 and Q5 in the Audi model series. To differentiate it from the Volkswagen models, This Audi Q3 will be tuned for more dynamic driving performance, a luxurious and personalized appearance, and equipped with adaptive shock absorbers, similar to those used in TT equipment
