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)

Chery QQ3EV New Energy introduce

The QQ3 pure electric vehicle is a small pure electric sedan developed on the Chery S11 vehicle platform. The vehicle is equipped with a 60V 6KW electric drive system and a 150Ah high-performance power battery The entire vehicle manufacturing process of QQ3 pure electric vehicle is very mature, following the traditional automobile manufacturing process platform, and there is no significant difference in appearance from the traditional QQ3. The word "EV" at the tail can distinguish it as a zero emission, pollution-free green transportation vehicle. The internal space and other aspects are also similar to the traditional QQ3. According to technicians, the motor tachometer has replaced the traditional engine tachometer, making it easy to monitor the operating speed of the motor in real time; The battery level is converted into voltage and displayed on the traditional QQ3 car fuel gauge. The ideal vehicle speed and battery level are marked in green to remind drivers to operate the vehicle better and extend its lifespan
