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)

Jaguar XF introduce

As Jaguar's mid to large-sized luxury sedan, it is divided into standard, travel, and XFR performance versions. In terms of design, the Jaguar XF leans more towards the XK's car making concept, full of a modern atmosphere: a grand front face, smooth body lines, and a leopard head logo embedded in the middle of the intake grille, highlighting the extraordinary momentum of the car. The Jaguar XF has a very spacious interior that can easily accommodate five adults, complementing the exterior style The XF also boasts exquisite craftsmanship, providing a revered driving experience. In addition, the sequential shift system provides the driver with a one touch manual shift function through the shift paddles on the steering wheel; Drivers can choose from 21 transmission modes to adapt the throttle process and gear shifting strategy to actual road conditions and driving environment
