A uniflow scavenging 2-cycle engine includes a cylinder (110) inside which a combustion chamber is formed; a piston which slides within the cylinder; a scavenge port (124) which is provided on one end side in a stroke direction of the piston in the cylinder to suck an active gas into the combustion chamber in accordance with the sliding movement of the piston; and a fuel injection unit (128) which has an injection port (128e) located on the outside of the cylinder, and injects the fuel gas into the active gas sucked into the scavenge port. As a result, it is possible to provide a uniflow scavenging 2-cycle engine capable of achieving a configuration which injects the fuel gas into the active gas flowing from the scavenge port by a simple machining, without decreasing the strength of the inner wall of the scavenge port. |
