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)

M-Benz A-Class introduce

The previous Mercedes Benz A-series was launched in 1997, with global sales reaching 1.1 million units. Mercedes Benz recently launched a more attractive and innovative new A-series in the hope of continuing the myth of the A-series. The new A-series is planned to be officially launched in the autumn of 2005. The new A-series has two main styles: a five door hatchback and a three door hatchback, which was first introduced in the A-series. The wheelbase of the new A-series is 2.57 meters, 1.76 meters wide, and 1.59 meters high, with a significant increase in the size of the four door model compared to the previous generation. The body of the new A-series, coupled with a series of emphasized horizontal lines, is 3.84 meters in size, allowing for driving. The new A-class on the highway is even more eye-catching
