Abstract:
1. An internal combustion engine comprising a crankcase, and a plurality of cylinders provided on the crankcase, the cylinders spaced from each other in a V-shape such that a V-shaped space exists between the cylinders, wherein when the internal combustion engine is mounted on a vehicle, the cylinders are spaced from each other in a V-shape such that a first cylinder is inclined forward, and a second cylinder is inclined rearward, and the engine further comprising a control valve, and plural exhaust ports and plural intake ports communicating with an interior of the cylinders, wherein the control valve recirculates exhaust gas obtained from an exhaust port of the internal combustion engine into the intake ports of the internal combustion engine, the control valve disposed in the V-shaped space between cylinders, wherein channels are provided for supplying exhaust gas from the control valve to the intake ports of the cylinders, and wherein the actuator portion is disposed above a cylinder head of the first cylinder so as to be exposed to wind resulting from travel of the vehicle, and the valve portion is disposed behind the first cylinder so as to be substantially protected from exposure to wind resulting from travel of the vehicle.
