A Speed limiter is an engine control device which interfaces with the engine control unit (ECU) and speedometer of a vehicle to restrict the engine speed once the vehicle reaches a pre-configured speed. A speed limiter may work by reducing the airflow into the vehicle engine, the fuel supply to the engine, adjusting the accelerator pedal or adjust the timing of the engine’s ignition system to keep the vehicle from exceeding the preset speed limit imposed by the limiter. In the scenario of a passenger car, the reason for speed limiters is generally to prevent the vehicle from exceeding speeds that may affect certain design limitations and improve safety of the vehicle.
