ABSTRACT:
An exhaust gas recirculating system including two flow rate control valves which are actuated by means of diaphragms. The negative pressure in the intake system of an engine is independently introduced into diaphragm chambers of the aforesaid two flow rate control valves. Thus, the total quantity of recirculating gases is controlled by taking as a reference the quantity of the recirculating exhaust gases being introduced into a first flow rate control valve and adding to the aforesaid reference quantity the quantity of the recirculating exhaust gases being introduced into a second flow rate control valve. In addition, means which are controlled by controllers adapted to issue command signals upon receipt of signals from sensors adapted to detect the running conditions of an engine and a vehicle are built in the negative pressure pipes which communicate the intake system of an engine with the diaphragm chambers of the respective flow rate control valves, so that timing to recirculate exhaust gases and the flow rate of the exhaust gases may be controlled.
