Abstract

A concentric circular valve train valve mechanism for internal combustion engine, including a frustum of a cone profile combustion chamber; the cone cup, cambered ceiling chamber is symmetrical easy grade. The surface of combustion chamber is circular grating beam frames, using central valve seating as the benchmark to divide concentric annular intake and circular exhaust valves, formed intake and exhaust passage top-down. Intake and exhaust valves are coplanar vertically distributed in inner and outer concentric circles; opening and closing of intake and exhaust valves is realized by SOHC single overhead camshaft driving valve rocker arms. Using SOHC single overhead camshaft to drive rocker arms to adapt the concentric circular intake and exhaust valves opening and closing simplifies system structure and zooms 100% engine intake and exhaust efficiency for boosting output power.
