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)

Range Rover Evoque introduce

The Range Rover Evoque is the most compact SUV model in the Land Rover brand. As the mass-produced version of the Land Rover LRX concept car, it is positioned slightly higher than the Freelander series. The Range Rover Evoque made its global debut at the Guangzhou Auto Show in December 2010 and established the Chinese name "Range Rover Evoque". The Range Rover Evoque officially entered the Chinese market in the second half of 2011, with a regular version priced at 528000 to 638000 yuan, divided into three door and five door versions. Since then, Land Rover launched the Victoria Limited Edition Aurora model in 2012, with power performance similar to the regular version, and luxurious and elegant interior materials, priced at 988900 yuan
