摘要： PURPOSE:To prevent the vapor lock by upwardly arranging the opened port part of a return pipe connected to a carburetor inside a fuel reservoir and connecting a circulation pipe for returning vapor to a fuel tank, over the return pipe. CONSTITUTION:The fuel in a fuel tank 1 is introduced from a connection port 6 into the fuel reservoir 5 of a vapor separator 4 through a pipe 11 and sent into a carburetor 2 by a fuel pump 3 through a pipe 12 from the connection port 7 of the fuel reservoir 5. The fuel generated in vapor form through the warming in the carburetor 2 is discharged into the fuel reservoir 5 from the opened port 8a of a return pipe 8, and accumulated into the upper part of the fuel reservoir 5, and the vapor is separated and returned into a fuel tank 1 through a circulation pipe 9, and thus circulation is performed.

摘要： PURPOSE:To improve startability by composing the float valve of a carburetor with a control part of a small diameter that opens and closes a fuel supply port and a base of a large diameter that is guided in a groove, so as to introduce supply fuel into a float chamber through a fuel leading passage. CONSTITUTION:To the float chamber 4 of a carburetter 3, fuel is supplied from a fuel tank 5 through a fuel supply port 4a and a float valve 7 that opens and closes said supply port and via a fuel leading passage 4c and a fuel storage chamber 21. The float valve 7 consists of a control part 7b of a small diameter that opens and closes the fuel supply port 4a and a base 7a of a large diameter, and the base 7a slides in a guide hole 4b formed in the carburetor. At engine starting, when a connecting passage 18 is opened as a starting fuel passage by operating a by-pass valve, the fuel from a fuel supplying pipe 20, opens the float valve 7 for flowing into stably without being affected by vapour in the carburetter-interior 3 and so on.

摘要： PURPOSE:To improve uneven combustion apt to be generated at the time of low rotation, low throttle valve opening, and the like, and also improve the increase of discharge of hydrocarbon into exhaust in a two-cycle engine utilizing exhaust pulsation in order to improve output during high rotation. CONSTITUTION:A two-cycle engine 16 is provided with a throttle valve 24 in an exhaust pipe 22. This throttle valve 24 is interlocked with a throttle valve 39 so as to throttle exhaust passage area when the throttle valve opening is low. In this case, the throttle valve 24 is formed in such a way that the ratio Ks of the exhaust passage area throttled by this throttle valve 24 to the sectional area of the exhaust pipe 22 satisfies the relation of 0.02
