Engine runs at its best in a certain RPM range and hence it is the task of Transmission system to allow the engine to run in the desired RPM range and provides different speeds and torques to the driving wheels with the help of gear box. Various components of a Transmission system are:  Flywheel  Clutch  Gear Box  Universal Joints  Propeller Shaft  Differential  Axles Transmission of a 4 wheel drive Automobile 2|Page 1.Flywheel In a 4-Stroke Engine, we have one power stroke and 3 idle strokes, but we need a constant engine speed at the driving wheels. This is accomplished using a Flywheel. A flywheel is a rotating mechanical device that is used to store rotational energy. Flywheels have a significant
