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)

Volt introduce

The Chevrolet Volt is a versatile and environmentally friendly electric concept car under the Chevrolet brand. It made its debut at the North American International Auto Show in January 2007. The unique feature of this car is that it is the only one that can be compatible with many new energy technologies that bring competitive advantages to General Motors. Click here to add a picture to illustrate the solution The Volt is equipped with General Motors' latest generation power propulsion system - the E-flex system, which is a very flexible electric vehicle architecture that perfectly solves the global adaptability problem of automotive energy. The Chevrolet Volt is expected to be introduced in China in 2011, with a market price of around 496000 yuan
