The application of automotive electromagnetic technology plays a crucial role in modern automobiles. The following are the main aspects of automotive electromagnetic applications:
Electrical system: Electricity plays a core role in modern cars. The 12 volt system is commonly used on buses, and in order to meet the growing demand for electricity, the development of a 24 volt system has begun. These systems are used for starting, lighting, and ignition systems, control circuits for horns, turn signals, emergency 4-way flashing lights, automatic transmission, and overdrive, windshield wipers and washers, fuel indicators, cigarette lighters, and dashboard lighting and warning indicators
Engine control: Electromagnetic sensors play a crucial role in engine control. For example, every time the signal rotor rotates through a convex tooth, a cyclic alternating electromotive force is generated in the sensing coil. The microcontroller can use this to calculate the time required for the crankshaft to rotate one degree at different speeds and the position of its ignition advance angle
Electromagnetic valve: Electromagnetic valve is an executive component of electronic control system, widely used in various parts of automobiles, such as shift solenoid valve, locking solenoid needle valve, and pressure regulating solenoid needle valve. With the continuous growth of the automotive market and the strengthening of environmental protection policies, solenoid valves play an important role in emission control and other aspects, and their market demand continues to rise
New material applications: In automotive manufacturing, new magnetic materials such as rare earth permanent magnets and new soft magnetic materials are widely used in electromagnetic injection valves ABS motor, starter motor and other components are used to reduce the weight and volume of the components
In summary, electromagnetic applications not only improve the performance and efficiency of automobiles, but also play an important role in achieving vehicle lightweighting and energy conservation and emission reduction. With the advancement of technology, electromagnetic applications will play a more important role in the future development of automobiles.
