Abstract:
1. An intake air control system of a V-type internal combustion engine having cylinder axes formed in a substantial V-shape with a crankshaft provided therebetween, comprising: an operation input shaft turnably driven by an operator's input; an operation input shaft turning angle sensor that detects a turning angle of said operation input shaft; and a throttle body is formed with an air intake passage for each of a plurality of cylinders and includes a plurality of throttle valves, a throttle valve correcting actuator; and a differential throttle control device having an input portion and an output portion, wherein said operation input shaft is located between valve shafts of a pair of the plurality of throttle valves that are disposed on opposing first and second bank portions of the V-type internal combustion engine, when viewed from the direction of the crankshaft, said operation input shaft is disposed separately from said throttle valve shafts; said operation input shaft turning angle sensor is disposed at a shaft end of said operation input shaft, and said differential throttle control device enables said throttle valve correcting actuator to output a difference between a turning angle of said operation input shaft and a turning angle relative to an opening angle of said throttle valve determined in response to an internal combustion engine state.
