ABSTRACT:
A two-stroke engine having an intake valve and an exhaust valve which are arranged on the cylinder head. A masking wall is formed on the inner wall of the cylinder head to mask the valve opening between the valve seat and the peripheral portion of the intake valve, which is located on the exhaust valve side, for the entire time for which the intake valve is open. Due to the masking wall, fresh air fed into the cylinder is turned around a central axis perpendicular to the axis of the cylinder. A fuel injector is arranged on the inner wall of the cylinder on the central axis to inject fuel therefrom along the central axis.
