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)
On the eve of the Beijing Auto Show on April 18, 2014, SAIC Volkswagen Skoda announced the official launch of its new upgraded travel vehicle, the Rapid Spaceback Xindong. In September 2015, the Shanghai Volkswagen Skoda brand's upgraded style hatchback, the Rapid Spaceback Xindong, was launched in 2016. In March 2016, the new Xindong was officially launched with a starting price of 69900 yuan. The new Xindong was enthusiastically endorsed by the Pancake Man Dapeng. Xindong will improve its configuration on the basis of the 2015 model, Its design will remain largely consistent. In terms of powertrain, the Xindong will still be equipped with a 1.4T.1.6L engine
