Embodiment Construction
[0084] figure 1 Motor vehicle 19 with internal combustion engine 1 and control device 20 is shown.
[0085] Internal combustion engine 1 has an external low-pressure exhaust gas recirculation device 2 and a plurality of cylinders 3 with an input side 4 and an output side 5 . Arranged on the intake side 4 is an air supply line 6 with a raw air inlet 7 and a filter arranged on the raw air inlet 7 , a raw air valve 26 and a second regulating valve 8 . Arranged on the outlet side 5 is an exhaust gas line 9 and an exhaust gas recirculation line 10 , which connects the exhaust gas line 9 upstream of the second control valve 8 and downstream of the raw air valve 26 with the air supply line 6 . During operation of the internal combustion engine 1 , the recirculated EGR exhaust gas mass flow is regulated via a first regulating valve 11 arranged in the exhaust gas recirculation line 10 12 and adjust the raw air mass flow through the second regulating valve 8 13 or total mass flow o...
