Leaf spring bellows internal combustion engine

摘要

A four-cycle internal combustion engine (100) has a bellows leaf spring (106) working in a compression mode or a tension mode. The leaf spring (106) is connected to a crankshaft (113) and forms a movable portion of a bellows chamber (116) that receives exhaust gases from an engine cylinder (110). As the exhaust gases transfer from the cylinder (110) to the bellows chamber (116), the gases push on the leaf spring (106) thereby transferring energy to the crankshaft (113).
