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)

Volvo V50 introduce

The Volvo V50 series, which debuted in 2004, is a Wagon model derived from the S40, a four door RV. Therefore, its exterior design also roughly continues the design foundation of the S40. In Taiwan, the general agent introduced the V50 equipped with a new 2.2-liter D5 diesel engine to Taiwan in conjunction with a small facelift of the V50 in Europe. Recently, the V50 D5 R-Design model, which is equipped with the original factory air power kit, was also introduced
