Zusammenfassung:	Methods and systems are provided for a high-pressure exhaust gas recirculation (EGR) system of a parallel twin-turbocharged internal combustion engine. Using an EGR cooler with a single exhaust inlet and outlet to cool recirculated exhaust gas may increase the complexity and size of the engine package, along with adding unnecessary cost from extra ductwork to decrease the chance of turbocharger boost imbalance. To provide a way to reduce package size without affecting engine performance, an EGR cooler with two exhaust inlets and outlets is used to cool exhaust flows leading from two cylinder banks.
