Abstract
An air-cooled internal combustion engine has a cylinder block, a piston slidably disposed in a cylinder in the cylinder block, and a cylinder head mounted on the cylinder block and having a partly spherical combustion chamber aligned with the cylinder. An intake valve, an exhaust valve, and a spark plug which are mounted in the cylinder head are oriented radially outwardly from the axis of the cylinder and angularly spaced from each other by distances that are progressively increased in the direction along the axis of the cylinder. The intake valve, the exhaust valve, and the spark plug have respective central axes inclined at the same angle to the axis of the cylinder, and the intake valve, the exhaust valve, and the spark plug are angularly spaced at equal angular intervals as viewed along the axis of the cylinder.
