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)
The Jianghuai Ruifeng M3 is a small MPV launched by Jianghuai Automobile for small and private business owners, as well as small and medium-sized merchants and other "maker" groups. It has advantages such as low fuel consumption, large space, and high safety. On July 23, 2016, the IKEA version of the Ruifeng M3 was launched simultaneously in ten cities including Lhasa, Chengdu, Chongqing, Baoding, Zhengzhou, Wuhan, Guangzhou, Qingdao, Xuzhou, and Ningbo. The IKEA version of the Ruifeng M3 inherits the business value of the old Ruifeng M3 and has a huge space among other models in the same class, And with business characteristics such as strong power and low fuel consumption, there are multiple innovations in the commercial field
