power of engine.
2) governer control the engine speed.
3) engine is a prime mover.

Answer / harish

A Dynamometer is a device used to caliculate power of the
engine

A governour is used to maintain constant speed at any
condition either heavy load or light load on the engine

Engine is the heart of the automobile through which power
is generated .

Answer / nitin g dahat

Dynamometer use to measure torque.

Governor use to maintain constant speed of a mover i.e.
tubine irrespective of the load variation.
