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 Hongqi L5 is an E-Class sedan with 100% independent intellectual property rights, created by China FAW after the successful launch of the Hongqi L platform product development and production preparation after the 2009 Hongqi brand inspection vehicle project. Its design continues the design of the Hongqi CA770, and the front face design is inspired by the 2009 National Day inspection vehicle CA7600J, including classic elements such as circular headlights and streamlined red flag logos at the front. The overall design is grand and dignified. The car was once used as a Chinese diplomatic concierge, Appearing in many major diplomatic occasions
