摘要： PROBLEM TO BE SOLVED: To suppress disagreeable noises attributable to the difference in frequency of the pressure pulsation caused by the difference in passage length by setting the passage length from a throttle valve to a suction passage to be substantially equal to each other while miniaturizing an air intake device. SOLUTION: The length L2 between both ends 15a and 18a in the direction of the cylinder bank in second upstream end opening parts 15a-18a is set to be shorter than the length L3 between both ends in the direction of the cylinder bank in intake ports 8 opened in one side part of an engine unit 2 and arranged continuous in the direction. The length L1 between both ends 11a and 14a and 12a and 13a in the direction of the cylinder bank in first upstream opening parts 11a-14a is set to be shorter than the length L2 between both ends 15a and 18a in the direction of the cylinder bank in the second upstream opening parts 15a-18a. The first upstream end opening parts 11a, 12a and 13a and 14a partially overlapping each other are arranged substantially on the same circumference with respect to the second upstream end opening parts 16a and 17a located in the middle with respect to the direction of the cylinder bank.

摘要： The invention relates to a crankcase scavenged internal combustion engine (1) of two-stroke type, comprising a cylinder (2) with an inlet tube (10) for air/fuel mixture and a number of transfer ducts (20), a carburetor (12) connected to the inlet tube (10), and an air inlet (24) provided with a restriction valve (25) whereby a piston ported air passage (23, 22, 26, 21) is arranged between the air inlet (24) and the upper part of the transfer ducts (20). The engine's air inlet (24) extends at least partly below and outside the carburetor (12), resulting in a more compact engine design and improved use of the space around the cylinder. Moreover, the cooling air gets better access to the cylinder.

摘要： PROBLEM TO BE SOLVED: To provide a part fitting structure capable of preventing a fall-out when fitting a projecting part of a part to a fitting recessed part of a member for fitting of the part. SOLUTION: A lock part 1d is formed at a position separated from the projecting part 1a, and the member 15 for fitting of the part is formed with a recessed part 15b for fitting of the projecting part 1a, and the lock part 1d is locked with a lock member 30a to connect the member 15 for fitting of the part to the part 1. It is necessary for the projecting part 1a to move on an arc around the lock position A to get out of the recessed part 15b. A distance r2 from the lock position A to a point C of the projecting part separated farthest from the lock position A is formed larger than a distance r1 from the lock position A to a point B of the recessed part inlet separated farthest from the lock position A to prevent a fall-out of the projecting part 1a from the recessed part 15b.
