Abstract

The invention relates to an internal combustion engine system (1), particularly in a motor vehicle, comprising an internal combustion engine (2), a fresh gas system (3) for supplying fresh gas to the internal combustion engine (2), an exhaust gas system (4) for discharging exhaust gas from the internal combustion engine (2), and an exhaust gas recirculation system (5) for removing exhaust gas from the exhaust gas system (4) at a removal point (11) and introducing the removed exhaust gas into the fresh gas system (3) at an introduction point (12). In order to improve exhaust gas recirculation, the exhaust gas system (4) is equipped with an exhaust gas valve (14) downstream of the removal point (11) in order to control the penetrable cross-section of the exhaust gas system (4).
