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)

Cadillac CT5 introduce

The Cadillac CT5 was officially released at the 2019 New York Auto Show and was launched in overseas markets in August; In terms of appearance, the CT5 also follows Cadillac's latest exterior design, which is divided into two styles: the sports version and the fashion version, with a sleek design. The Cadillac CT5 adopts an electronic gear lever, and the control knob of the multimedia system is located behind the gear lever. In terms of power, the Cadillac CT5 is equipped with a 2.0T turbocharged engine and a 3.0T twin turbocharged engine. The transmission part is matched with a 10AT gearbox, and high-end models will also provide a four-wheel drive system
