Abstract (en)

[origin: WO2021083485A1] Emission treatment systems for internal combustion engines are known comprising a crankcase (10), a tank (26), a crankcase ventilation line (32), a tank ventilation line (62) and an oil separator (38), into which the crankcase ventilation line (32) feeds. According to the invention, in order to reduce the number of aggregates used for emission treatment, a pressure difference can be created by the oil separator (38) and the tank ventilation line (620 feeds into the oil separator (38). In this way, a separate flushing pump can be dispensed with.
