Abstract
A piston and cylinder are oblong in cross section with the major dimension at right angles to the crankshaft axis. An inlet valve and an exhaust valve are mounted near opposed end portions of the oblong cylinder with a spark plug arranged along the minor centerline, either between the valve or displaced laterally from the major centerline of the cylinder. The valves are symmetrically inclined with respect to the central axis of the oblong cylinder, and are operated from separate camshafts. The combustion chamber roof is a concave surface having both major and minor centerline surface elements which employ radii of curvature greater than the radius of curvature of the cross-sectional ends of the oblong cylinder.
