METHOD FOR OPERATING AN APPLIED-IGNITION INTERNAL COMBUSTION ENGINE WITH DIRECT INJECTION

摘要

Embodiments for operating an engine with direct injection are provided. In one example, a method for operating an applied-ignition internal combustion engine having at least one cylinder and direct injection comprises raising a component temperature of an injection device of the at least one cylinder at least locally in a region of a catalytic coating in order to initiate and assist oxidation of coking residues. Thus, deposits of coking residues may be counteracted even in part-load operation.
