Flywheel and Governor

Flywheel- Flywheel distributes the available energy uniformly throughout the cycle and reduces the variation in the speed of engine. It acts as a reservoir of energy. It stores energy when the energy produced is more than requirement i.e. during power stroke, and gives away to the engine during idle stroke. The flywheel stores energy by […]
