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)

Third generation Grace introduce

The third generation can be said to be the highest level among domestic brands, so in terms of interior design, it is also quite eye-catching. It adopts luxury seats covered with imported genuine leather, which are spacious and thick, comfortable to ride on, and can easily adjust the seat layout to meet the needs of mobile commerce, office work, and large luggage handling, It can be quickly transformed into a luxurious and comfortable "soft sleeper" private room. Combined with high-quality DVD entertainment system and spacious and transparent front and rear double skylights, the seating experience is better. As a business vehicle, whether there is enough space and comfort is also very important. This requires you to personally experience it, and you can get a satisfactory answer. There are four rows of passengers in each row, and there is enough legroom, compared to those of family models, There is simply a world of difference, and not only that, the rear passengers also have independent and practical air conditioning control panels. In order to achieve multifunctionality, the rear two rows of seats in the car can be adjusted in multiple directions, which is convenient and practical!
