ABSTRACT:
A two stroke oscillating piston engine comprising cylinder sections provided with feed chambers for additional fresh air. The two outer rings, acting as pistons, draw in fresh air through intake ports and force that air to enter combustion chambers through communication ducts and ports. The middle ring is intended for the fresh gas supply of the combustion chambers. The radial grooves for fresh air are provided at a shorter distance from the ports than the radial grooves for fresh gas. Burnt and expanded gas is first exhausted from the combustion chambers by fresh gas; then the combustion chambers are filled with fresh gas and fresh air. Thus, exhausting unburnt gas together with burnt gas is avoided and improved combustion is provided in the combustion chambers.
