Abstract
A method for determining the trapping efficiency and/or a scavenging air mass of an internal combustion engine has the steps of: for operating points (BP), in which a scavenging of a cylinder of the internal combustion engine with air takes places, an efficiency curve (η, η) of the internal combustion engine is created as a function of an injection mass (m) of fuel in the cylinder, and on the basis of the efficiency curve (η, η) an optimum injection mass (m) for an optimum efficiency (η) of the internal combustion engine is determined, which is a measure for the trapping efficiency and/or a measure for the scavenging air mass of the internal combustion engine.
