Abstract

A method for the formation of a combustible fuel/air mixture in a combustion chamber of a direct-injection internal combustion engine with an injection nozzle, which has a closure body includes the steps of injecting at least two partial quantities of fuel into the combustion chamber and moving the closure body of the injection nozzle into its closed position after the injection of each of the partial quantities of fuel.
