ECOLOGICALLY CLEAN ENGINE Russian patent published in 2000 - IPC

FIELD: mechanical engineering; engines. SUBSTANCE: in proposed engine non-traditional supply sources are used such as photosynthesis, piezoeffect and others. For this purpose pins of hollow stepped rod of piston are made in form of at least two pairs enclosing (enclosed by) cosine shaft and connected by crosshead sliding bearing in longitudinal slots. Self-alignment bearings are used in engine. Slots are made concave (convex), and nonsplit piston and rod rings are installed. Ring piston can be made in form of diaphragm. Two-sided supply chambers can be made for ring pistons (diaphragms). EFFECT: provision of economic ecologically clean engine. 6 cl, 10 dwg
