Abstract

Enhancements introduced to two-stroke cycle piston internal combustion engines with recoil sweep; with an arrangement of the exhaust and sweep ports, which is mainly vertically with respect to the axis of the cylinder, other auxiliary ports having an axial dimension smaller than that of the ports itself, having been added to the sweep ports, characterized by the fact that the sweep ports constitute a group that lies on the axis of symmetry, of the arrangement of the ports, and that the exhaust ports are arranged in two groups at both ends of the group of the sweep ports.
