The engine flywheel is made from cast iron with a steel ring gear.The flywheel is fastened by means of a flange with bolts to the crankshaft and there is a phonic wheel for the rpm sensor towards the engine side.
The engine flywheel is the component that ensures that the engine rotation is even, accumulating energy during the active stages (expansions) and restoring it during the passive stages.The flywheel is designed to allow the engine to idle without cutting out and overcome the friction developed whilst it is running in no load conditions.
