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)

Besturn B70 introduce

The Pentium B70 has a small change. It is a highly anticipated independent product of FAW sedan. Although it heavily draws on the technology of the joint venture Mazda 6 and is produced in the same line as Mazda 6, it is a true independent brand product. The Pentium B70 has undergone 3 million kilometers of road testing and has undergone 518 inspections The launch of this car not only demonstrates the strong technical strength of FAW Pentium, but also reflects its development strategy of focusing on green and environmental protection, as well as independent technological innovation. From previous test cars, the new generation B70 adopts the Pentium family's hexagonal grille on the front face, and the headlights also adopt a wing shaped contour design. From the appearance of the B90 at the Beijing Auto Show, The replacement B70 may adopt the family front face design of the new generation Pentium family represented by the B90
