摘要： A fresh gas system for a piston engine has a collecting line for supplying fresh air to multiple individual lines. The fresh gas system has the collecting line which is unthrottled and a control unit for actuation of the additional valves is designed so that it subdivides a fresh gas charge of the combustion chamber which depends on the load state into two charging phases (A, B) within an intake time window (T). This is limited by the opening and closing of the intake valve such that it actuates the additional valve to close within the intake time window (T) at a closing point in (TS). This depends on the load state and then actuates it to open at a later opening point in time (TO) that depends on the load state of the piston engine.

摘要： An internal combustion engine system includes a fresh air system, an exhaust gas system and an exhaust gas recirculation system. The exhaust gas recirculation system has an exhaust gas valve assembly for controlling a removal flow at a recirculation line removal point and a fresh air valve assembly for controlling an introduction flow at a fresh air line introduction point. The exhaust gas valve assembly is permanently displaceable between a first position and a second position for generating the removal flow. The fresh air valve assembly is permanently displaceable between a first position and a second position for generating the introduction flow. The valve assemblies are synchronized such that the positive pressure pulses entering at the removal point into the recirculation line meet the negative pressure pulses at the introduction point.
