Abstract
The two-stroke engine includes at least one cylinder, a piston reciprocable within the cylinder and a cylinder head which contains at least one exhaust port which is controlled by a poppet valve and at least two inlet ports which are controlled by respective poppet valves and are connected to respective inlet ducts. The inlet ports are of directed type with the axes of the inlet ducts being convergent in the direction of flow whereby the air flowing through them into the cylinder flows preferentially generally towards the cylinder axis. The axes of the inlet ducts pass substantially through the cylinder axis where the air flows through the inlet ports merged to form a single air flow on or adjacent the cylinder axis.
