Abstract: Method for configuring a functionality of real and/or simulated control units, comprising a functionality belonging to a functionality class, such that the functionality has one or more functions and parameters dependent on the functionality class. The functionality is further assigned to at least one control unit. The functionality class has categories, including an else category and a default category and its functionalities each belong to a category. A predetermined value is stored for parameter and if the functionality is assigned to the default category, the predetermined value is adopted for the parameter. If the predetermined value of the parameter changes, the change is adopted for all functionalities which have already been assigned to the default category. And the control unit assigned to the functionality is configured with the function and the values of the parameters of the functionality.

Abstract: Method for configuring at least one first functionality of real and/or simulated control units (ECU1, ECU2), wherein the first functionality belongs to a first functionality class (F1, F2), wherein the first functionality comprises at least one function dependent on the first functionality class (F1, F2) and at least one first parameter (P1, P2, P3, P4, P5, P6) dependent on the functionality class (F1, F2), wherein the first functionality is assigned to at least one control unit (ECU1, ECU2), the first functionality class (F1, F2) has, as categories, an else category (ELSE) and at least one first default category (K1, K2, K3, K4), wherein the functionalities in the first functionality class (F1, F2) each belong to a category (K1, K2, K3, K4, ELSE), wherein a first predetermined value (V1, V2, V3, V4) is stored for the at least one first parameter (P1, P2, P3, P4, P5, P6) for the first default category (K1, K2, K3, K4) and, if the first functionality is assigned to the first default category (K1, K2, K3, K4

Abstract: A fuel filter of an internal combustion engine including a filter housing having a lowermost housing base and a topmost removable housing lid. The filter housing has one raw fuel inlet and one pure fuel outlet. A replaceable annular filter insert mounts there in the filter housing, fuel flowing through it from outside towards inside. The filter subdivides an interior space of the filter housing into a raw zone and a pure zone. A supporting body is arranged in the interior of the annular filter insert, a first flow channel and a second flow channel extending therethrough. The first flow channel connects at one end to the pure zone and at the other end to the pure fuel outlet. The second flow channel connects at one end to the raw zone via a vent throttle or a vent valve and at the other end to a reservoir return in the filter housing.
