Abstract
A main passage mounting a throttle valve and an air bypass flow passage for reducing HC emission by promoting atomization of the fuel spray injected from the assembly pipe fuel injector are integrated in a body of an intake air control device arranged upstream of an assembly pipe in a one-piece structure to form a unit. Thereby, the intake air control device can be easily manufactured and easily mounted on and dismounted from the intake air system. The amount of HC emitted during warming-up operation of an internal combustion engine is reduced by efficiently supplying fuel spray injected from an assembly pipe fuel injector at the time of starting and warming-up operations for the internal combustion engine.
