Patent ID: 8499880

Claim:
A vehicle, comprising: an engine body mounted on a vehicle body frame with an axis of a crankshaft arranged in a longitudinal direction; an intake device comprising a throttle body, wherein the intake device is connected to a rear-side surface of a cylinder head which constitutes a part of the engine body, and wherein a posture of the throttle body is set such that an axis of an intake passage which is formed in the throttle body extends in a rearward and downward direction; an injector configured to inject fuel toward an intake port of the cylinder head, wherein the injector is mounted on an upper portion of the throttle body in a state where an injection axis of the injector is directed to a curved outer peripheral side of the intake port, wherein the intake port is formed in the cylinder head of the engine body which has a cylinder axis thereof inclined toward either a left side or a right side, the intake port comprising a common passage portion configured to open on a rear-side surface of the cylinder head and a pair of branched passage portions that are branched from the common passage portion in a bifurcated manner such that the branched passage portions are individually communicated with a pair of intake valve ports formed in the cylinder head so as to open on a ceiling surface of a combustion chamber, wherein an axis of the common passage portion is set in an offset manner toward an inclination side of the cylinder axis with respect to a plane which is arranged at the center between both the intake valve ports and extends parallel to the cylinder axis, and wherein the throttle body is arranged such that a center axis of the throttle body which extends in the vertical direction is inclined in the same direction as the cylinder axis in conformity with the inclination of the cylinder axis, and an axis of the intake passage of the throttle body obliquely intersects with the axis of the common passage portion of the intake port.
