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)

Renault chose the single door sedan as a single wooden bridge out of helplessness towards the fiercely competitive three door and two door cars, but more opportunities. The increasing market share of single door cars year by year proves the diversification of buyer demand. Through investigation, Renault found that although three door cars still dominate the mainstream (49.4% in Western Europe in 2000), the market share of single door cars that Renault has singled out on its own is also increasing, reaching 16.3%, A considerable number of people are seeking cars that can better express their personality beyond the traditional three box structure. This is exactly what Renault has discovered as a space for expression, and it is also one of the reasons why Renault's cars are becoming more and more peculiar. Not only does it have aesthetic results due to its cultural roots, but it also has independent understanding and judgment of the market
