Vehicle speed governor or vehicle speed limiter is a device used to restrict the top speed of the vehicle for security reasons, widely used in public service vehicles (buses, school buses) and heavy goods vehicles.
The vehicle is already equipped with an onboard speed limit system to prevent the vehicle exceeding certain speed. However, the traffic might get dangerous with the pre-controlled speed especially for school buses, public buses and heavy construction trucks. Then external speed limiter (speed governor) is needed to ensure the public security.
Well, here are some things you may want to know about the speed governor.
1. Speed governors contribute to safety as well as reduce fuel use and tyre wear with the speed set at a level optimum for these factors. Even if an accident will be inevitable, it’s impact will be very significantly reduced.
2. Road speed governors were developed to improve road safety and the environment by controlling the top speed of vehicles, thus reducing serious accidents and pollution.
The main work of the devices is to limit the maximum speed of a vehicle to a preset level whilst the throttle pedal is fully depressed, without a noticeable variation in the speed. Precise control of fuel causes an optimum performance of the engine, results in ideal firing with minimum exhaust gases and thus reduces air pollution.
3. Speed governors helps reduce fuel cost: The reduction of fuel cost is an important part of most businesses. The reduction of carbon dioxide emissions is also becoming a major factor for most companies. When a reduction in fuel consumptions recorded, a reduction in carbon dioxide emissions is also apparent.
The increase in fuel economy is not the only benefit however; as the operating RPM is much lower at 70mph as opposed to 80mph the engine and vehicle component wear can also be reduced.
How it works (Principle of operation): The electronic control unit is powered by battery through the ignition switch. When ignition is turned on, the ECU is powered. The ECU activates the motor unit which rotates anti – clockwise, thereby equaling the length of the spring Rod to that of the length of the original connecting rod, to allow maximum acceleration.
4. Speed Governors constantly monitor the speed of a vehicle: When the vehicle is in motion, the Electronic control unit receives beyond pulses from the speed sensor and computer speed of the vehicle. It constantly monitors the speed of the vehicle.
When the speed of the vehicle reaches the set speed, the ECU activates the solenoid valve by means of which the flow of diesel is regulated. This controls the fuel flow to the engine resulting in a stabilized speed.
