Gas guiding system for a periphery of an internal combustion engine for guiding gas of the internal combustion engine, internal combustion engine and method for operating the internal combustion engine

摘要

The invention relates to a gas guidance system (10) for a periphery of an internal combustion engine (20) for guiding gas of the internal combustion engine (20), comprising: an inlet-side gas supply (1) for supplying gas to the internal combustion engine (20); a downstream gas discharge (2) with an exhaust gas aftertreatment system (14) for discharging gas from the internal combustion engine (20); and a first gas version (3) for carrying out a first partial gas flow (7) comprising at least one cylinder (A1-A6) of a first cylinder group and a second gas version (4, 3.1) for carrying out a second partial gas flow (8) from at least one cylinder (B1 -B6, A1-A3) of a second cylinder group, wherein for the case of a partial operation of the internal combustion engine (20) the at least one cylinder (A1-A6) of the first cylinder group is designed for operation with injection and the at least one cylinder (B1-B6, A1-A3) of the second cylinder group is designed for operation without injection. According to the invention, it is provided that the first gas version (3) and the second gas version (4) are connected to one another via a gas-conducting connection having a first separating means, wherein the first separating means is designed to close the gas-conducting connection in the case of partial operation ,
