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)

Beijing Mercedes Benz GLK Class introduce

The Beijing Mercedes-Benz GLK300 is equipped with Mercedes-Benz's 4Matic all-wheel-drive system, which means that all four wheels of the GLK will always have power transferred to the wheels from the engine via the transmission. This means that all four wheels of the GLK will always have power from the engine via the transmission and the splitter to the wheels. The GLK is not equipped with front or rear differential locks. The GLK is not equipped with front or rear differential locks. When one of the wheels slips, the 4Matic system uses the limited-slip function integrated into the ESP to lock one wheel by using the brakes to transfer power to the other wheel, thus realizing a function similar to differential lock.
