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)

SAIC Volkswagen Langjing introduce

As another crossover car under the Shanghai Volkswagen brand, the Cross Lavida adopts a more sporty honeycomb mesh grille design on the front face. The front and rear crossover style bumpers and side panels form a large surround of the Cross Freedom Realm, bringing a strong sense of hierarchy. The silver wild fun roof luggage rack. 16 inch sharp aluminum alloy wheels with sleeve exhaust pipes, these wild or sporty elements combine to add more vitality to the side of the Lavida, Under the influence of the high mounted chassis of the hunting equipment, the minimum ground clearance of the Langjing has increased by 10mm compared to the Langxing, and the 130mm size will bring good passability performance. It is a soul car designed for consumers who pursue freedom and can walk as they please, leading car owners to break free from constraints and follow their inner feelings. It made its global debut at the 2013 Chengdu Auto Show
