| 摘要 |
The port-controlled two-stroke engine (1) comprises a combustion chamber (8), a crankcase (2) containing a combustible mixture, a cylinder (5), a piston (15) working in the cylinder (5), an intake duct (17) terminating in an intake port (18) in the cylinder wall for delivering the combustible mixture to the engine (1), and at least one flywheel mounted to rotate in the crankcase (2) about an axis of rotation. The rotation of the flywheel acts to drive the boundary layer of the combustible mixture immediately adjacent the periphery of the flywheel around the periphery. The engine (1) further comprises a transfer passage (21), extending from a first transfer port (22) in the cylinder wall adjacent the crankcase (2) to a second transfer port (23) in the cylinder wall adjacent the combustion chamber (8), for conveying the combustible mixture from the crankcase (2) to the combustion chamber (8), the first transfer port (22) being located in a radial direction with respect to the axis of rotation.
