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)

Great Wall Haval H2 introduce

The Haval H2 is a small SUV launched by the Haval brand under Great Wall Motors, with a body size of 4330/1815/1700mm, which is very close to that of a compact SUV. In the current environment where SUV models are gradually entering the "micro era", Great Wall Motors will launch this small SUV, which will also become another highly promising domestic brand SUV model. At the 2014 Beijing Auto Show, Haval announced the mid-range price of two wheel drive manual for 105800 yuan, Whether its price close to that of a joint venture car can withstand the test of the market and consumer recognition still requires time and the quality of the H2 itself. On September 28, 2018, the 2018 Haval H2 Creative Edition was officially launched for sale
