Systems and methods for exhaust gas recirculation

A system and method of exhaust gas recirculation (EGR) in an internal combustion engine are provided. The EGR system includes a first EGR flow path and a second EGR flow path independent of the first EGR flow path that are each configured to recirculate high pressure exhaust from the exhaust system...

Beschreibung
Zusammenfassung:	A system and method of exhaust gas recirculation (EGR) in an internal combustion engine are provided. The EGR system includes a first EGR flow path and a second EGR flow path independent of the first EGR flow path that are each configured to recirculate high pressure exhaust from the exhaust system back to the engine intake system. The system includes a controller in operable communication with the EGR system configured to selectively control an amount of EGR flow through at least one of the first and second EGR flow paths.
