Abstract

PURPOSE: To reduce the production of smoke by controlling the amount of exhaust gas to be circulated in accordance with the movement of fuel lever of governer and the rotation of engine.
CONSTITUTION: The suction/exhaust tubes 11, 12 of a DIESEL engine 10 is conducted through a EGR tube 20 having EGR valve 21. A vacuum tank 31 is coupled through a control valve 40 and a delay valve 50 to the negative pressure chamber 22 of the valve 21 which is regulated by the negative pressure regulated with the air through a control valve 40. A rotation sensor 80 for a distribution pump 70 having far fall speed governer and a position sensor 90 for a fuel lever 91 are connected through a power source 61 to the control valve 40 to perform the opening control of the valve 40 in accordance with the signal from both sensors.
