Abstract

The invention relates to an internal combustion engine system, especially in a motor vehicle, comprising an internal combustion engine, a make-up gas installation for supplying make-up gas to the internal combustion engine, an exhaust gas installation for evacuating the exhaust gas from the internal combustion engine, and an exhaust gas recirculation installation for extracting exhaust gas from the exhaust gas installation and introducing the extracted exhaust gas into the make-up gas installation. In order to improve the exhaust gas recirculation, two make-up gas paths through which make-up gas can flow in parallel are formed in a control section of the make-up gas installation, a make-up gas valve being arranged in each make-up gas path, for controlling the cross-section of the respective path through which gas can flow.
