Abstract

A spark ignited internal combustion engine includes a cylinder block defining a cylinder which accommodates a piston and is closed by a cylinder head. One of the opposed surfaces of the piston and cylinder head affords a recess constituting a combustion chamber. The outer edge of the recess is defined, when viewed in plan, by two arcs, the radius of curvature of each arc being less at one end than at the other, the decrease in the radius of curvature being in the same sense in the two arcs. In use, when the piston is performing its compression stroke at least two swirl patterns are produced in the inlet charge of air and fuel in separate portions of the combustion chamber in the same sense about respective axes parallel to the axis of the cylinder.
