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)

Caravan introduce

The parameters in terms of appearance and power are shown in the table above. As the models to be launched in China this time use the fourth generation from North America (instead of the fifth generation 2008 Dodge Caravan model that was unveiled at the Detroit Auto Show earlier this year with a brand new platform), the relatively outdated engine and gearbox brought by the relatively old platform can be said to be the biggest regret of entering the domestic model. However, in fact, the GL8, which is in competition with it, is already a discontinued model in North America, and the same weaknesses also exist in its competitors
