Concentric circular valve train valve mechanism for internal combustion engine

Abstract

A concentric circular valve train valve mechanism for internal combustion engine, including a frustum of a cone profile combustion chamber 1; The top surface of combustion chamber 1 is circular grating beam frames 2, using central valve seating 3 as the benchmark to divide concentric annular intake valve (8, Fig. 1) and circular exhaust valve (6, Fig. 1); Intake and exhaust valves are coplanar in inner and outer concentric circles; opening and closing of intake and exhaust valves is realized by SOHC single overhead camshaft 18 driving valve rocker arms 16, 17; Using a single overhead camshaft to drive rocker arms to actuate the concentric circular intake and exhaust valves opening and closing simplifies system structure and improves engine intake and exhaust efficiency for boosting output power.
