<p>PURPOSE:To prevent an interference between an intake system and a body of autobicycle by a method wherein the intake ports are opened in V-shaped space formed between both cylinder blocks and a reed valve is installed at each of the intake ports. CONSTITUTION:An intake port 24 is arranged such that it may be opened at V- shaped space 30 defined between the first and second cylinder blocks 161, 162 and the third cylinder block 162, and then a reed valve 29 is installed at the end of the port. The reed valve 29 is fixed to the cylinder block 161 by a bolt 35 along with an intake pipe 34, and a carburettor 31 is connected to the intake pipe 34 at the V-shaped space 30. The intake port of each of the cylinder blocks is opened at the V-shaped space formed between both cylinder blocks, and a reed valve preventing a back-flow of intake mixture is installed at each of the intake ports at the V-shaped space, so that it becomes possible to install each of the cylinder blocks at the V-shaped space of the intake system.</p> |
