Abstract
An internal combustion engine includes a spring housing rotatably mounted to the engine's engine housing for rotation about an axis of rotation. An energy storing mechanism including at least one elastic member is housed within the spring housing. A spring loading mechanism includes at least one roller movable into and out of engagement between the engine's flywheel and the spring housing, such that rotation of the flywheel is converted through the at least one roller to cause rotation of the spring housing in a direction that loads the elastic member. An engine starting mechanism includes a helically threaded member interconnected with the spring housing and a starter pinion threaded onto the helically threaded member. Rotation of the spring housing in response to unloading of the elastic member causes the starter pinion to move into engagement with the flywheel, thereby rotating the flywheel and starting the engine.
