What is the Principle of Engine Speed Limiting?

[LaylaLee]

The principle of engine speed limiting is that when the ignition device loses the ignition signal, it loses its ignition function, causing the engine to shut off. Once the engine shuts off, the rotational speed decreases. Specific reasons for the engine speed limiting principle: When the driver's speed continuously increases to the set speed limit and also reaches the set buffer time without deceleration, the system enforces the speed limit. The throttle automatically adjusts and cannot supply more fuel. Once the speed drops below the set limit, the speed limit is lifted, and the fuel system returns to normal. The car engine speed limiter system includes: Throttle pedal, electronic control unit, motor, throttle mechanism. The driver presses the throttle pedal according to the power required for driving, and the throttle pedal position sensor converts the collected throttle pedal position signal into an electrical signal.
