Abstract
In a method for operating an internal combustion engine, in particular a spark-ignition engine, having inlet valves for controlling air flow to the internal combustion engine, which air flow is compressed by an exhaust gas turbocharger, wherein, during partial load operation, the inlet valves are closed at an early first point in time (t1) or at a late second point in time (t2), and during a transition from partial load operation to full load operation, for a predefined time, the inlet valves are closed at an early third point in time (t3) or at a late fourth point in time (t4) with the third point time (t3) occurring after the first point in time (t1) and the fourth point in time (t4) occurring before the second point in time (t2).
