Abstract
A uniflow scavenging 2-cycle engine includes a cylinder inside which a combustion chamber is formed; a piston which slides within the cylinder; a scavenge port 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 which has an injection port located on the outside of the cylinder, and injects the fuel gas into the active gas sucked into the scavenge port.
