Abstract

The invention relates to a method for operating a common rail injection system of an internal combustion engine. According to the invention, each main fuel injection (311, 312) is preceded by at least one pilot injection activation (321, 331) and at least one pilot injection activation (331) is carried out over such a short period of time that it does not result in an injection valve of the common rail injection system opening and closing.
