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)

Brilliance BMW X1 introduce

The domestically produced Brilliance BMW X1 and the imported version X1 are almost identical. For BMW, there are no missing iconic details. The front face still features the standard dual kidney grille, coupled with the energetic triangular eyes, giving the entire front face a certain aura. The main difference between the domestically produced X1 xDrive20i and 28i on the front face is that they use a black grille while the 28i uses a chrome grille, The 28i has an additional horizontal chrome strip on the lower grille compared to the 20i. On the side of the Brilliance BMW X1, there is not much decoration, and a slightly upturned waistline gives its side a sense of power. The snowflake shaped five spoke aluminum alloy wheels add some fashionable elements to this sense of power, and the two are well integrated. On the C-pillar at the rear of the car, The classic corners of BMW are clearly visible, while the 28i has an additional silver skirt trim on the side compared to the 20i. At the rear, X1 continues to follow the rugged route of an SUV, but what reflects this ruggedness is the few simple lines. The large rear window occupies the majority of the rear. The sharp LED tail lights in the shape allow X1's body lines to continue here. The difference between the 20i and 28i at the rear is not significant, Mainly in terms of the silver trim on the rear bumper, the 28i is taller
