Abstract
An intake air control system of a V-type internal combustion engine having cylinder axes formed in a V-shape with a crankshaft provided therebetween is provided. An operation input shaft driven by an operator's input and an operation input shaft turning angle sensor that detects a turning angle of the operation input shaft are also provided. A throttle body having a throttle valve is formed with an intake passage for each of the cylinders. The operation input shaft is located between valve shafts of an opposing pair of throttle valves that are located on opposing bank portions of the V-type internal combustion engine, when viewed from the direction of the crankshaft. The operation input shaft is disposed separately from the throttle valve shafts and the operation input shaft turning angle sensor is provided at a shaft end of the operation input shaft.
