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)

BMW X3 introduce

The BMW X3 intelligent all wheel drive system can flexibly and quickly distribute driving force between various axles according to specific road conditions. BMW has also created the concept of a sports and leisure vehicle for new models. You can occasionally drive it to the countryside for some less intense outdoor driving, but most of the time it will patrol the city. So, Components such as non load bearing bodies, solid axles, and non independent suspensions seem to have become relics of the original off-road vehicle. Conservatives believe this is a major deviation, while most customers believe it is a correct response to market demand and should be pleasing, At least it still retains the most desirable advantages of off-road vehicles: a sturdy and sturdy body, spacious indoor space, high seat position, and broad driving vision. The various control components are clear and accurate. The driving control is very agile, with sporty driving performance, very accurate steering, and clear road feel. Driving on multi bend roads can bring more fun to the driver, making you full of confidence. The classic inline 6-cylinder engine runs smoothly and has abundant power, Showcasing BMW's distinctive features
