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)
What is needed is a sharp appearance, agile acceleration, and sharp handling. Nissan engineers believe that the design of the rear diffuser has been improved with this belief, which can make the airflow flow out of the car more quickly. The new guide holes on both sides of the lower part of the rear bumper are designed to introduce airflow, Helping improve the cooling efficiency of the rear brake system. Another obvious change is the use of larger diameter exhaust pipes in the new car, which in our opinion can only be considered as decoration
