An internal combustion engine having at least one cylinder in which at least one piston is reciprocable; the air, or air and fuel, induction being by means of an inlet port giving rise to helical flow of air, or air and fuel within the cylinder. In one form, the inlet port is substantially tangential to the cylinder. The cylinder may have a pair of pistons therein movable in unison to adjacent top dead center positions wherein they define with the cylinder wall, an annular combustion chamber.
