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)

Discover the magic introduce

On September 19, 2014, Land Rover officially launched the Discovery Sport model at the foot of the Great Wall, officially named the "Discovery" in China, making it the first 7-seat model in the mid-size luxury SUV market. It could be considered the successor to the LR2, but according to Land Rover's latest plans, it will be included in the Discovery lineup and positioned slightly above the LR. At the same time as the release of the actual car, Land Rover officials also announced the pre-sale price of the Discovery, which is expected to be around 600,000 yuan. In the 2014 Guangzhou Auto Show, Land Rover's Discovery was officially launched, the new car launched a total of two models, priced at 55.8-61.8 million yuan.
