Claims

[Scope of utility model registration request]

An intake port that is opened and closed by a piston, an exhaust turbine supercharger that supercharges supply air to an intake passage that communicates with the cylinder through the intake port, an injector that injects fuel into the vicinity of the intake port, and a cylinder. A two-stroke engine characterized by comprising an exhaust valve provided in the head and driven to open and close in synchronization with changes in crank angle.
