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)

Ford Forrest introduce

The Ford Focus was developed by British engineers at Ford in 1964. It began mass production at the end of 1967 and made its debut at the Brussels Motor Show in early 1968. It not only existed as a successful compact family car, but also opened the way for Ford to participate in rally events with a sporty version of an economy RV in Europe, Ford has established a sporty and avant-garde image in this segment of the car market. The Forex is a brand new mid size new model family sedan that integrates Ford's global product development resources and strength, as well as a deep understanding of consumer demand in China, the world's largest automotive consumer market
