<P>PROBLEM TO BE SOLVED: To provide an idle air controller arrangement structure of an internal combustion engine enabling a reduction in the size of a motor itself since the motor of an idle air controller driven by the motor is less affected by the heating of cylinders, the circulation of air is improved, and the motor can be cooled by running wind. <P>SOLUTION: An on-vehicle V-type internal combustion engine having throttle bodies in intake passages 50f, 70f, 50r, and 70r extended upward from the inner walls of the V-banks of the plurality of cylinders arranged in V-configuration comprises bypass passages 100 and 101 allowing the upstream side to communicate with the downstream side of throttle valves stored in the throttle bodies in an intake passage. An idle air controller 90 formed of an idle air control valve 92 interposed in the bypass passages 100 and 101 and the motor 97 driving the idle air control valve 92 is disposed adjacent to the intake passages 50f and 70f on the outside of an area surrounded by the plurality of intake passages 50f, 70f, 50r, and 70r. <P>COPYRIGHT: (C)2007,JPO&INPIT |
