Method for treating exhaust gas and arrangement of an exhaust gas system on an internal combustion engine

1. A method for treating exhaust gas of an internal combustion engine, the method comprising:

supplying exhaust gas from at least one first cylinder of the internal combustion engine via a first exhaust gas line to a first, small duct of an asymmetrical turbine of an exhaust gas turbocharger, and onto a particle filter; and

supplying exhaust gas from at least one second cylinder of the internal combustion engine via a second exhaust gas line to a second, larger duct of the turbine, and onto the particle filter,

wherein when it is determining that the particle filter should be regenerated the method further comprises

introducing less fuel into the at least one first cylinder than into at the least one second cylinder,

at least partially recycling the exhaust gas exiting from the at least one first cylinder into an intake air tract of the internal combustion engine,

completely supplying the exhaust gas of the at least one second cylinder to the particle filter,

at least partially blocking the exhaust gas line via which the exhaust gas of the at least one first cylinder is supplied to the particle filter,

dispensing with post-injection into the at least one first cylinder and into the at least one second cylinder, wherein an amount of fuel introduced into the at least one second cylinder is greater by a reduction in fuel introduced into the at least one first cylinder, wherein a torque of the internal combustion engine is at least essentially maintained at a level achievable when a quantity of fuel to be provided for the torque is uniformly distributed over the both the at least one first and at least one second cylinders of the internal combustion engine.

2. The method of claim 1 , wherein a quantity of exhaust gas recycled into the intake air tract of the internal combustion engine is adjusted by an adjusting device configured to at least partially block or open up the exhaust gas line.

3. The method of claim 2 , wherein the internal combustion engine is operated in a low to medium load range, so that the exhaust gas line is completely blocked, and the exhaust gas exiting from the at least one first cylinder is completely recycled into the intake air tract of the internal combustion engine.

4. The method of claim 1 , wherein the internal combustion engine is operated in a low to medium load range, so that the first exhaust gas line is completely blocked, and the exhaust gas exiting from the at least one first cylinder is completely recycled into the intake air tract of the internal combustion engine.

5. The method of claim 4 , wherein the internal combustion engine is operated in a load range of 400 Nm to 800 Nm.

6. The method of claim 1 , wherein the at least one first cylinder and the at least one second cylinder are each supplied with intake air via a same intake air tract.

7. The method of claim 1 , wherein the at least one first and at least one second cylinders of the internal combustion engine are supplied with unthrottled intake air.

8. The method of claim 1 , wherein the exhaust gas of the at least one first cylinder mixes with the exhaust gas of the at least one second cylinder at the most downstream from the turbine.

9. The method of claim 1 , wherein a total quantity of fuel that is injected into the at least one first cylinder is 40% to 100% of a total quantity of fuel that is injected into the at least one second cylinder.
