PURPOSE:To reduce the pumping loss of the engine during a low-speed rotation of the engine by providing an exhaust gas regeneration control valve which opens in inverse proportion to the range of the opening degree of an accelerator pedal when the opening degree of the accelerator pedal is smaller than a predetermined value. CONSTITUTION:A charger 10 is provided with a rotary shaft 18 having at its both ends a compressor wheel 14 disposed in a suction air passage 13 which is led to the suction air vlave 12 of a diesel engine 11, and a turbine wheel 17 disposed in an exhaust air passage 16 from an exhaust air valve 15 of the engine 11. In the above described arrangement is provided an exhaust gas reflux passage 20 which connects an exhaust gas take-up port 19 formed between the exhaust valve 15 and turbine wheel 17 to a suction air passage 13 between the suction valve 12 and the compressor wheel 14. This passage 20 is controlled by a control valve 21. The control valve 21 opens the accelerator pedal 35 through transmitting members 29-33 in inverse proportion to the range of the opening degree of the accelerator pedal 35 when the opening degree of the accelerator pedal 35 is smaller than a predetermined value. |
