Abstract: An internal combustion engine system includes an internal combustion engine, a first turbine unit receiving exhaust gases from the internal combustion engine, the turbine unit having a compressor for compressing intake air and feeding the intake air by an air intake line to the internal combustion engine, and an exhaust gas recirculation line connecting the air intake line with an exhaust as line of the internal combustion engine at a position upstream the first turbine unit. A bypass line connects the exhaust gas recirculation line to the exhaust gas line at a position downstream of the turbine unit, the bypass line having an arrangement for controlling the exhaust gas flow from the exhaust gas recirculation line to the exhaust gas line.
