INTAKE AIR DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide an intake air device of an internal combustion engine capable of excellently mixing fuel and air by reducing a wall surface sticking quantity of injection fuel. SOLUTION: A fuel injection nozzle 24n of a fuel injector 24 arranged downstream of an intake air flow control valve 22 in an intake pipe 21, is arranged in a position B separate from a main flow Im exceeding the main flow Im formed by the intake air flow control valve 22. The fuel is injected in the direction (the straight line AB direction) for separating from the main flow In.
