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 new model of Hyundai, the Deli Terracan, is known as the king of SUVs. Together with the Santa Fe, it has become two exciting and distinctive mid size SUVs for Hyundai Motor Company. Its appearance has enhanced Hyundai's competitiveness in the SUV market. The Deli Terracan combines the comfort of a sedan with the practicality of a truck, and can adapt to various uneven road surfaces Elegant, powerful, and practical, Terracan provide a broad front view, making driving safer, more comfortable, and scientifically designed. The dashboard can coordinate with every eye and hand movement of the driver to save reaction time and achieve the best safety effect. The rear seat can be partially or fully folded to accommodate trapped luggage. Other small designs inside the car are also very thoughtful, such as an electric adjustable sunroof, air conditioning, a CD box that can hold 8 discs, and a small drawer under the seat Equipped with passenger protection system and ABS technology, Deli Terracan has won the highest five-star safety rate
