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)

Baojun 730 introduce

The Baojun 730 is a household MPV product under SAIC-GM Wuling Baojun. The car was officially launched in the second half of 2014. The overall design of the Baojun 730 adopts a similar style to the Baojun 630. The car adopts a seven seat layout, with a maximum cargo space of 1680L. The Baojun has put forward the theme of "family makes life better" for the 730 model. Although it is somewhat emotional, it cannot be denied that this is a model specifically designed for families, And it is aimed at markets like a family of three with elderly people from both sides, making the 7-seater design very necessary. The Baojun 730 also emerged in this situation
