摘要:
A scooter type vehicle provides a pair of right and left frame members (202,203) in the interior of a vehicle body cover so as to extend substantially horizontally between a head pipe (201) and the front end of a seat. Right and left footrest plates (215) are provided outside on the right and left of the vehicle body cover. An engine is provided between the right and left frame members (202,203) with the cylinder axis of the cylinder block being provided so as to extend longitudinally, and the center axis (12d) of a crankshaft is provided so as to extend laterally and to be located above the upper surfaces of the right and left footrest plates (215) as seen in a side view. A balancer shaft is located below the crankshaft, and the crankshaft and the balancer shaft are sandwiched and supported between the upper and lower case halves with their center axes being located on the joining surface.

摘要:
In an intake passage (23) structure of an internal combustion engine configured such that a cylinder head (4) is formed integrally with an intake manifold portion (24) and a cylinder central axis (A) is made generally parallel to the extending direction of an intake passage (23) as viewed from the side, an injector (26) is disposed so that its leading end is oriented toward the direction of an intake valve (18) while preventing interference with peripheral parts. An injector (26) is disposed at the intake manifold portion (24) so as to be oriented toward an intake valve (18) of a cylinder head (4) and an intake passage (23) on the upstream side of an injector attachment position is offset in a width-direction of an internal combustion engine.
