エンジン。[Scope of Claim for Utility Model Registration] In a two-stroke engine in which an injector is attached to the scavenging port of the cylinder of the two-stroke engine body, and a scavenging pump and a load control means are connected, the above-mentioned scavenging port is installed in the exhaust port at least when the piston is rising. An exhaust rotary valve is provided whose valve timing is set so that the exhaust port closes before the scavenging pump closes. A fuel-injected two-stroke engine characterized by injecting fuel into the cylinder.
