Beschreibung
Zusammenfassung:	An internal combustion engine for a vehicle has an exhaust gas recirculation system for returning exhaust gases to the engine intake passage. The carburetion system for the engine includes a fuel enrichment valve. Sensors for high vehicle speed and low vehicle speed control the fuel enrichment valve and a valve in the recirculation passage so that the fuel enrichment valve and the exhaust gas recirculation valve are controlled in a manner so that exhaust gas recirculation and fuel enrichment are increased in a lower vehicle speed range, and decreased in a higher vehicle speed range.
