Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for revitalization start of a particle filter for a direct-injection diesel engine with a common-rail injection system. SOLUTION: The method for revitalization start of the particle filter for the diesel engine with the common-rail injection system, which allows for a fuel injection method with which one or more of the following are performed in each engine cycle and each engine cylinder: a main injection; the first preliminary injection preceding the main injection, which is performed in a compression stroke; the second preliminary injection preceding the main injection and following the first preliminary injection; the first subsequent injection following the main injection; and the second subsequent injection following the first subsequent injection which is performed in an exhaust stroke. The method for revitalization start, in which the second preliminary injection and the first subsequent injection are performed in full proximity to the main injection so that they can be connected with the main injection in a real fuel combustion stage.
