PROBLEM TO BE SOLVED: To provide an intake device of an internal combustion engine capable of suppressing dispersion of amounts of an EGR gas distributed to each of intake pipes while suppressing lowering of torque in an internal combustion engine by suppressing degradation of inertia supercharging effect.SOLUTION: In an intake device 100 of an internal combustion engine, a length (total length Lp) of an intake port P from a surge tank 10 to a combustion chamber R of an engine 110 has a length to exert inertia supercharging effect, EGR gas introduction ports 23 of four EGR gas distribution pipes 34 are disposed on positions to make a volume Ve of the intake port P from the surge tank 10 to the EGR gas introduction port 23 be equal to or more than a volume Vi of the EGR gas introduced to an intake pipe 21 from the EGR gas distribution pipes 34 during one cycle of the engine 110, and positions at a surge tank 10 side (upstream side) with respect to the center O in a circulating direction, of the intake port P.SELECTED DRAWING: Figure 5 |
