Abstract
A method for operating an internal combustion engine is provided. The method comprises, during low and medium load conditions, introducing fuel from a fuel tank by intake pipe injection into at least one intake air line coupled to at least one cylinder, and during high load conditions, introducing the fuel from the fuel tank by direct injection into the at least one cylinder. In this way, the method of fuel delivery may be optimized based on the load conditions.
