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)

corolla introduce

The Corolla is the tenth generation straight upgrade product of Toyota COROLLA. Since its release in November last year, the Corolla has received global consumer attention; Now, this globally popular car has settled in FAW Toyota, once again allowing Chinese consumers to experience Toyota's latest technology and driving experience simultaneously. The predecessor of the Corolla was the AE86! The size of the Corolla body has significantly increased compared to the previous generation Corolla, and the entire vehicle has shown an unprecedented "wide and low" trend, creating a spacious interior space; The newly developed dual VVT-i technology with 1.6-liter and 1.8-liter engines will bring a more powerful power experience in the future The Corolla, the tenth generation Corolla that has been officially released in China and has become the focus of attention at the Beijing and Shanghai Auto Show, is the latest model in its series. It was officially launched on November 16, 2006. The Corolla, which is about to be launched by FAW Toyota, has two displacement models: 1.6L and 1.8L. Whether in terms of appearance, configuration, or power, the Corolla, The Corolla has been greatly improved on the basis of the old Corolla. The average fuel consumption of the Corolla is 8.88L/100km, and car owners have expressed that its fuel consumption is low. According to feedback from car owners in 2012, the Corolla has almost no problem with any malfunctions and its quality is very stable. Car owners generally recognize the Corolla in terms of acceleration and handling, Compared to the old Corolla, there has been a significant improvement. However, the 4-speed automatic transmission is slightly stingy. Car owners generally report that the fastest acceleration is achieved from 2nd to 3rd gear
