Abstract
In an internal combustion engine having an air intake system and an exhaust outlet system, and an exhaust gas recirculation system which has an exhaust-gas recirculation line and an exhaust-gas recirculation valve for supplying a controlled quantity of exhaust gas to the air intake system, the recirculation valve is separated from the apparatus which introduces the exhaust gas into the air intake so that it is exposed only to exhaust gas and not to the air intake flow.
