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)

Volkswagen Weilan New Energy introduce

In terms of interior design, both Volvo from Scandinavia and Volkswagen from Germany are based on simplicity. The Volvo V60 is designed with a simple yet luxurious feel, while the Volkswagen NIO maintains Volkswagen's stable T-shaped layout. It is worth mentioning that the biggest highlight of the all-new B8 in terms of interior design comes from the integrated front air outlet design, which is not a big change, but very clever. In terms of seats, The sports seat configuration of the Volvo V60 is obviously higher, with electric adjustment for both the driver and passenger seats, as well as seat memory function for the driver's seat. In contrast, the Volkswagen NIO has more options for seat adjustment. The electric backrest adjustment for the driver's seat allows for manual adjustment of the front and rear height of the seat. In addition, the front seats also have manually adjustable leg rests and headrests that can be adjusted up and down in four ways, although the configuration is not as good as the V60, However, it can provide a more comfortable sitting position. As a station wagon, storage space is equally important. In this regard, both models have their own advantages. Firstly, in terms of storage compartment settings, the Volkswagen Weilan has a more diverse storage compartment compared to the Volvo V60; In addition, in terms of practicality, the Volkswagen NIO also has advantages. Taking the storage compartment next to the rear door as an example, the Volkswagen NIO can easily accommodate two bottles of mineral water, while the V60 looks somewhat impractical; However, the advantages of V60 come from the design of some storage compartments, such as the layered design of the glove box and the multiple folding designs of the rear center armrest, which enhance the practicality of these two parts through design
