[0011] It is therefore worth striving to specify neither too small a value (which would lead to unnecessary downtime for the user of the internal combustion engine) nor too high a value for the TBO opening (TBO-Freigabe) (by said too high a value would increase the undesired breakdown of the internal combustion engine)

Embodiment Construction
[0112] Figure 1A An example of a movable machine part and at least one wear-resistant machine element holding the movable machine part is shown as a time-limiting machine element in an internal combustion engine, ie here at the crankshaft Background of the Fluid Dynamic Functional Principle of the Sliding Bearing Principle of the Bearing The connecting rod on the crankshaft and the bearing shell of the base bearing are in front of it.
[0113] For this, Figure 1A In view (i) is shown schematically an internal combustion engine 1 with a motor block 10 having a certain number (for example a number of 4, 6, 8, 12, 16 or 24 or similar) of Cylinders 11, 12 are schematically shown. Pistons 13 , 14 , which move accordingly in cylinders 11 , 12 , transmit the movement of these pistons via connecting rods 15 , 16 to crankshaft 20 . The connecting rods 15 , 16 are supported in each case on the crankshaft 20 with a connecting rod bearing 21 , wherein the crank arm 17 connects the conn...

The invention relates to a method (100) for operating an internal combustion engine (260, 420) with a motor, having a moving machine part and at least one machine element which retains said 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 (260, 420), wherein for the operation of the internal combustion engine (260, 420), a service-life-limiting time interval until the next maintenance of the internal combustion engine (260, 420) is specified, and the internal combustion engine has a number of service-life-limiting machine elements (262), wherein for the at least one service-life-limiting machine element (262) a remaining service life is forecast and the service-life-limiting time interval is determined therefrom.
Description
technical field [0001] The invention relates to a method for operating an internal combustion engine having a motor, the internal combustion engine having a movable machine part and at least one wear-resistant machine element holding the movable machine part, [0002] Machine elements such as, for example, supporting, sealing, guiding or similarly retaining parts that wear out during operation relative to movable machine parts, [0003] The machine element has a limited operating time for the operation of the internal combustion engine due to wear, wherein [0004] - for the operation of the internal combustion engine, the time interval until the next maintenance of the internal combustion engine to the limited running time is stated, and [0005] - The internal combustion engine has a certain number of time-limiting machine elements, wherein for at least one time-limiting machine element, the remaining operating time is predicted and the time interval for the time-limiting i...
