Abstract

An air-cooled internal combustion engine, a crankshaft and a camshaft rotatably journalled in the crankcase parallel to one another, and a cast intake valve chamber and cast exhaust valve chamber each cast integrally with the cylinder and communicating with the combustion chamber via a respective intake valve port and exhaust valve port.
Intake and exhaust valves are disposed for reciprocation in a direction lying perpendicular to the camshaft and simultaneously in a direction lying at an acute angle to a plane passing through the longitudinal axis of the cylinder and parallel to the axis of the camshaft. An intake cross-over manifold is cast integrally with the cylinder and is delimited by interior walls which are substantially straight in longitudinal direction from a fuel/air intake port to a point of intersection with the intake valve chamber.
