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)

British SX7 introduce

The British SX7 is Geely's second SUV model, offering six models with three power options: 1.8L, 2.0L, and 2.4L. The 1.8L engine has a maximum power of 102kw/6200rpm and a peak torque of 172Nm/4200rpm; The maximum power of the 2.0L model is 104kw/6000rpm, and the peak torque is 178Nm/4000-4500rpm; The maximum power of the 2.4L model is 119kw/5700rpm, and the maximum torque is 220Nm/4000-4200rpm. The transmission system of the 1.8L and 2.0L models is paired with a 5-speed manual transmission, while the 2.4L model is paired with a 6-speed automatic transmission
