ABSTRACT:
This invention relates to a method and device for recirculating the exhaust gases of internal combustion engines, utilizing means for injecting said gases into the engine induction manifold while mixing them with an adjustable-output induction air circulation controlling indirectly the metering of the amount of recycled gases. A recirculation conduit connects one portion of the exhaust system to one portion of the induction manifold and connected to said recirculation conduit upstream of its junction with the induction manifold, an induction air pipe line incorporating an air output adjustment valve the opening of which is controlled as a function of the desired metered amount of recycled gases.
