Many cars have speed limiters or RPM limiters to protect their engines from falling apart and destroying themselves.
One can buy speed limiters that can be attached to the engine/ignition/fuel control.
By fitting a throttle restrictor. This would have to be custom made, most garages would be able to do this work.
A variable speed governor is an engine part that works with the engine to govern speeds required within the engine. It serves to keep the engine at a steady speed as set by the operator of the vehicle.
Not sure of your question but if it is does a truck have a governor the answer is loosely yes. Cars and trucks have computers that govern their top speed by shutting off the fuel supply when they reach a preset speed.
Of course. Some people just don't have what it takes to regulate their own behaviour and that is why we have laws to govern road speed and other laws to protect people.
no.
In terms of physics its Instantaneous speed
Walking speed Bicycle speed Automobile speed Train speed Airplane speed Rocket speed
It reads instantaneous speed, and tells you nothing about average speed.
It limits or controls the speed of an object.
Look at your speedometer! automobile is right 40 mph is 40 mph regardless of wind.
It means the automobile is travelling at a constant speed in a particular direction.
it is a speed limiter of engine...control speed respect to load....
the need of gear box in automobile is to increase / decrease the speed while u driving the car
