<p>PURPOSE:To secure a required pipe length for a sufficient compactness by bending an intake pipe in the vicinity of an intake port downward, and the bending the lower end back upward. CONSTITUTION:Each intake pipe 16 extended from an intake port 15 of a cylinder head 12 is first bent downward in the vicinity of the intake port 15 to form a bent pipe 26. A down edge of the bent pipe 26 is then bent back after bent rearward, to formed a bent-back pipe 27. Consequently, the respective intake pipe 16 had a required length with a sufficient compactness.</p> |
