A method for operating an internal combustion engine with a motor, having a moving machine part and at least one machine element which retains the moving machine part and is subject to wear, such as, for example, a supporting, sealing, guiding or the like retaining machine element that is subject to wear during operation relative to the moving machine part, which machine element, because of the wear, is service-life-limiting for the operation of the internal combustion engine, wherein&#x2014;for the operation of the internal combustion engine, a service-life-limiting time interval until the next maintenance of the internal combustion engine is specified, and&#x2014;the internal combustion engine has a number of service-life-limiting machine elements, wherein for the at least one service-life-limiting machine element a remaining service life is forecast and the service-life-limiting time interval is determined therefrom.

A method for requirement-based servicing of an injector in a common-rail system in which, during ongoing operation of the engine, a current operating point is stored as a function of the rail pressure and of the fuel injection mass, and the current operating point is multiplied by a damage factor and is stored as a reference injection cycle as a function of the rail pressure as well as of the fuel injection mass. A total reference injection cycle is calculated by forming sums over the reference injection cycles, and a load factor is calculated as a function of the total reference injection cycle and the permissible injection cycles, and the load factor is set as decisive for the servicing recommendation of the injector.
