Internal combustion engine system

An internal combustion engine system, comprising:

• an internal combustion engine,
• a make-up gas installation for supplying make-up gas to the internal combustion engine wherein the make-up gas installation includes a control section,
• an exhaust gas installation for evacuating exhaust gas from the internal combustion engine,
• 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,
• at least two make-up gas paths through which gas can flow in parallel that are formed in the control section of the make-up gas installation,
• a make-up gas valve for each of the at least two make-up gas paths, wherein the make-up gas valve controls a cross section through which gas flows of the respective make-up gas path and controls an exhaust gas recirculation rate of the exhaust gas recirculation installation, wherein the make-up gas valve is arranged in the at least two make-up gas paths, and wherein the make-up gas valves are fast switching valves, and
• a valve control provided for actuating the make-up gas valves, said valve control driving during operation of the internal combustion engine the make-up gas valves to generate pressure fluctuations in the make-up gas installation,
• wherein said pressure fluctuations with regard to at least one of frequency and amplitude are a function of an exhaust gas recirculation amount to be adjusted, so as to adjust the exhaust gas recirculation amount as a function of an current operational state of the internal combustion engine.
