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)

Pentium B30 introduce

Before June 2010, the newly appointed Deputy General Manager of FAW, Wang Fachang, who was in charge of sales, revealed on various occasions that the Besturn B30 would officially be taken off the production line in the second half of 2010, and the B90 project, which was positioned as a higher level, was also being orderly promoted. However, the project of this entry-level A-class car with the model code B30 for FAW Besturn has been postponed to 2011 within FAW sedans, which means that there will be no new cars launched by FAW Besturn in 2010, As for the reason why the B30 project has been postponed to next year, FAW sedan personnel did not disclose specifically
