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)

The Great Wall Jiayu MPV, also known as COWRY in English, is the first MPV independently developed by Great Wall. It is positioned as a high-end business vehicle for enterprises, with 5 doors and 7 seats, a length of 4574 mm, a width of 1704 mm, and a height of 1845 mm. The entire vehicle has full and smooth lines, strong visual impact, and the tail wing is integrated with the body and headlights. Its prominent features are: abundant power, advanced technology, innovative interior style, fashionable appearance, spacious driving and comfortable space. The internal space is relatively small compared to commercial MPVs, Compared to the larger space of household MPVs, the moderately sized MPV market in China is precisely a blank spot, while Great Wall Jiayu has a relatively moderate space, filling the gap in this MPV market. Its 2.0-liter displacement gives it an inherent advantage in energy conservation and environmental protection, making it a model of the business MPV market
