Abstract
A uniflow two-stroke engine includes: a cylinder receiving a piston such that the piston can reciprocate therein and defining a combustion chamber above the piston; an exhaust port having one end in communication with an upper end portion of the cylinder; a scavenging port having a scavenging orifice at one end, the scavenging orifice being in communication with a lower part of a side portion of the cylinder such that the scavenging port is selectively brought into communication with and shut off from the combustion chamber by the piston; and an exhaust gas recirculation passage having one end in communication with a part of the side portion of the cylinder above the scavenging port and the other end in communication with the scavenging port such that the exhaust gas recirculation passage is selectively brought into communication with and shut off from the combustion chamber by the piston.
