INTRODUCTION OF EXHAUST GAS RECIRCULATION AT A COMPRESSOR BLADE TRAILING EDGE

摘要

Methods and systems are provided for injecting exhaust gases from an exhaust gas recirculation system proximate to a trailing edge of a compressor wheel of a compressor. In one example, a compressor of a turbocharger may include an exhaust gas recirculation inlet volute within a casting of the compressor. The exhaust gas recirculation inlet volute may include an injection port positioned downstream of the trailing edge of the compressor wheel for injecting exhaust gases into intake air flow.
