ASYMMETRIC EXHAUST GAS RECIRCULATION SYSTEM

摘要

Systems and methods for a twin turbocharged engine with a single exhaust gas recirculation (EGR) system are disclosed. In one example approach a system is provided comprising a first turbocharger in a first intake passage with a low-pressure EGR system fluidically coupling exhaust exiting the first turbocharger to intake air entering the first turbocharger, and a second turbocharger in a second intake passage without a low-pressure EGR system fluidically coupling exhaust exiting the second turbocharger to intake air entering the second turbocharger.
