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)

Toyota Yaris L introduce

The Toyota Yaris L, with a body length of 4115mm and a wheelbase of 2550, gives it a significant advantage in space and other aspects compared to competing models such as Honda Fit, Volkswagen Polo, and Ford Fiesta. This car has two powertrain options and six configuration models are available in China, The guide price ranges from 69800 to 108800 yuan. The Zhixuan does not have many configurations specifically designed to improve comfort. The seat positions of all models are manually adjusted. This sporty version of the model uses fabric seats, which are very sporty and wrap around the body well. However, the seat softness is not high, and sitting for a long time may be uncomfortable. In idle mode, the Zhixuan appears very quiet, but when the speed reaches a certain value, the noise becomes very obvious, At speeds of 60km/h and 80km/h, the noise levels are 59.8 and 62.3 decibels, respectively. At this time, most of the noise comes from the engine and wind noise, and there is no sense of the noise caused by resonance of certain components inside the car
