摘要： A scavenging port 24 is composed of a main port portion 28 directly ranging to a scavenging passage 22 and a port extension 30 extending from the main port portion 28 in the lateral direction. The port extension 30 extends to the opposite side of an exhaust port 10. A corner portion 40, where the port extension 30 and the scavenging passage 22 are in contact with each other, is composed of an inclined surface that gradually approaches a cylinder chamber 18 toward a gas mixture port 8.

摘要： A two-stroke engine (4) has a throttle motor (22) for driving a throttle valve (20), a fuel injection device (430) disposed in an intake system (18) including a crank chamber (420), and a control unit (24) controlling the throttle motor (22) and the fuel injection device. The two-stroke engine (4) is designed to achieve an engine rotation speed of 4,500 rpm to 7,000 rpm when the throttle valve (20) is fully open. The two-stroke engine (4) is operated with the throttle full open by the control unit (24), and a battery (8) is charged with electric power generated by a generator (6) using the two-stroke engine.
