PROBLEM TO BE SOLVED: To provide an ERG gas supply device for a diesel engine in which sufficient amount ERG gas can be supplied without the significant influence of the opening and closing conditions of a throttle valve. SOLUTION: An ERG gas supply device is composed of an intake pipe 10, a throttle valve 2 for intake amount adjustment provided in the intake pipe 10, and an introduction pipe 30 which opens an ERG gas supply port 3 in the intake pipe 10. Between the throttle valve 2 and the ERG gas supply port 3, a guide plate 15 which divide a passage into first passage 11 guiding the air flow of intake air to the ERG gas supply port 3 side and second passage 12 guiding the intake air flow to the opposite side of the ERG gas supply port 3 is disposed in the intake pipe 10. The throttle valve 2 is composed of a turning shaft 21 turning in the intake pipe 10 and a valve body 22, and the valve body 22 is disposed so as to turn in the direction of the first passage 11. |
