| 摘要 |
The invention relates to a method for operating an internal combustion engine in the form of a spark-ignition engine (2) having the following method steps: pre-compressing the air supplied to the combustion chambers (15A-15D) of the internal combustion engine (2), directly injecting fuel into the combustion chambers (15A-15D) of the internal combustion engine (2), and adjusting the valve overlap of the gas exchange valves corresponding to the load range in which the internal combustion engine (2) is operated, characterized by the following method step: carrying out the pre-compression in a charging device in the form of an exhaust-gas turbocharger having a turbine (5) with variable turbine geometry (VTG), wherein the engine exhaust gas is supplied to the turbine (5) via separate spiral ducts (17A, 18A; 17B, 18B) of a multi-flow turbine housing (16A; 16B).
