Zusammenfassung:PROBLEM TO BE SOLVED: To regulate a load by means of an exhaust valve alone by arranging an injector injecting fuel and the exhaust valve regulating an opening of an exhaust passage connected to an exhaust port arranged on the side wall of a cylinder in the middle of an intake system and controlling an intake air quantity by means of an operation of the exhaust valve. SOLUTION: In a fuel injection type two cycle internal combustion engine mounted in a motorcycle, a lead valve 228, an intake manifold, and an intake silencer are serially arranged in this order on the back face of a cylinder, while one end of an exhaust pipe is connected to the front face of the cylinder. An ignition plug 249 is installed in a cylinder head 244 installed in the projection end of a cylinder body 243, while an injector 264 is installed so as to be faced to a combustion chamber 248. An exhaust valve 281, which regulates an opening of an exhaust passage 253, is arranged, and an intake air quantity is regulated when the exhaust valve 281 is actuated via a wire by means of an operation of a throttle grip.
