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)

Tigong introduce

The Volkswagen Tiguan is a car produced by Shanghai Volkswagen, and its price was announced on March 26, 2010. This compact SUV was first introduced to consumers at the 2009 Guangzhou Auto Show. Once it appeared, it gained widespread attention and love. The appearance of the Tiguan broke the awkward situation of German cars without domestic SUV products, At the same time, it also provides consumers with more and better choices. The Shanghai Volkswagen Tiguan offers four versions, including the urban version, the fashion version, the elite version, and the flagship version, with seven models. They are equipped with Volkswagen's flagship 1.8TSI and 2.0TSI engines, which have excellent performance in both power performance and economy. Paired with a 6-speed manual transmission and an Aisin 6-speed automatic transmission, they can better exert power while enjoying the surging power, The emissions are also more environmentally friendly. Compared with the prototype Volkswagen Tiguan, the Tiguan has increased its length by 68mm and achieved a wheelbase of 2684mm, which is in the upper middle level among vehicles in the same class. The purpose is to meet the usage needs of the Chinese people. The luggage compartment of the Tiguan can freely change between 400L and 1530L, greatly improving practicality, which is also a point that must be paid attention to as an SUV model
