Abstract

PURPOSE: To regulate the EGR rate such that it is low for light engine load while it is high for high load, by providing an air providing valve interlocked with a throttle valve in an exhaust gas recirculator then regulating the negative pressure.
CONSTITUTION: An exhaust system (not shown) and a suction manifold 5 are conducted through a recirculation path 3 having an exhaust gas recirculation control valve 1 to return a portion of exhaust gas to the suction system. The negative pressure chamber 14 of the control valve 1 is conducted through a negative pressure path 6 to the suction system in the down stream of a throttle 42, to transmit the suction negative pressure. The exhaust gas pressure from a pressure chamber 30 is applied on the negative pressure path 6 to conduct a pressure regulating valve 2 for regulating the negative pressure to vary the negative pressure by the air from an air inlet 26. A tapered valve 82 interlocked with the throttle valve 42 is located advancably and retreatably at the air inlet port 27 at the tip of the inlet 26 which will advance during low opening while retreat during high opening.
