Abstract:
In a method for operating an internal combustion engine having at least one cylinder which includes a first exhaust valve and a second exhaust valve, the internal combustion engine is operated in a scavenging operating mode in that the closing times of the exhaust valves after an ejection stroke of a four-stroke operating cycle are situated after an opening time of an intake valve, and the second exhaust valve is opened with a time delay relative to the first exhaust valve in the scavenging operating mode.
