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 H2S introduce

The Haval H2s is the latest small SUV of the Haval brand, which is naturally associated with the Haval H2 in its name. However, this brand new small SUV has a smaller body size and wheelbase than H2, so it is actually not closely related to H2. However, in terms of appearance, it is also in line with the trend. The family style design style is exquisite and atmospheric, and the brand recognition is high. For a younger consumer group, in terms of market positioning, the H2s is lower than H2, The style is also very different from H2
