Abstract
Systems and methods are provided for reducing coking residues on an injection device of an applied-ignition, direct injection engine. An example system comprises an injection device; an electric heating device integrated with the injection device; a catalytic coating on a surface of the injection device; and a controller suitable to initiate a cleaning mode of the injection device wherein the electric heating device raises the temperature of the injection device. Heating the injection device allows coking residues on the injection device to oxidize in the presence of the catalytic coating.
