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)

JETTA introduce

In 2004, Jetta made 21 improvements, inheriting excellent quality and performance such as strong power, low fuel consumption, and durable leather. The appearance is more coordinated, and the overall impression is atmospheric, masculine, and modern. With reliable quality and a complete service system, the new Jetta once again created a sales miracle Jetta is a car brand of Volkswagen AG in Germany. Jetta MK1 was launched in Europe in 1979. From its structure, Jetta (including later Vento/Bora) is a Golf with added trunk, and Jetta can be seen as a derivative of Golf. Volkswagen AG's marketing strategy positions it as a family mid size RV one level higher than Golf, and its sales in the European market have always been lower than that of Golf, In other markets that prefer sedans, the situation is exactly the opposite. Jetta is a car brand produced by FAW Volkswagen Co., Ltd., a joint venture of Volkswagen Group in China
