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 exterior design of the Ouliwei comes from Changan Automobile's European and Italian designers. In terms of styling, it has long been the foundation of the concept car, which was the VOSS concept car. However, the difference between the mass-produced version and the concept car is very large. Except for a slight inheritance of the cabin part, the design elements on the concept car are rarely preserved. The front grille is similar to the Acura, and the headlight contour is large, with only the sunken waistline design on the side being preserved, And it is this waistline style that connects the Olivier with the VOSS concept car
