Embodiment Construction

[0067] exist Figure 1A A first variant of the block diagram schematically shows a first exemplary embodiment of a method 10 for determining oil consumption in an internal combustion engine not shown in detail. exist Figure 1B A second embodiment of the method 20 according to a second variant is shown in . For the sake of simplicity, the same reference signs are used for identical or similar elements or elements with identical or similar functions.

[0068]The method 10, 20 first receives I at least one operating parameter that has a decisive effect on oil loss, then derives II a criterion for oil replacement from the at least one decisive operating parameter, and finally outputs III the relevant oil loss according to the criterion. replacement information. According to the concept of the invention, two method steps are carried out for deriving the II criterion. In the first step (a), a plurality of decisive operating parameters are converted into a plurality of characteri...

Abstract

The invention relates to an internal combustion engine, in particular to a method (10, 20) of determining oil deterioration in a diesel engine or a gasoline engine, comprising the following steps: receiving (I) at least one operating parameter for determining the oil deterioration; deriving (II) a criterion (9) for an oil change from the at least one operating parameter; outputting (III) information (16) relative to the oil change according to the criterion (9); according to the method, input parameters (E1...E6) of a neural and / or probabilistic computer network (1) having a plurality of determining functions are converted into a number of state parameters characterizing the oil as output parameters of the computer network (1), wherein (b) at least some of the output parameters are subjected to a check, the criterion (9) being derived from the check.

Description

technical field [0001] The invention relates to a method for determining oil loss in an internal combustion engine, comprising the steps of: receiving (Aufnehmen) at least one operating parameter decisive for oil loss; Criterion (Kriterium): The information related to the oil change is output according to the criterion. The invention also relates to an electrical device for controlling and / or regulating an internal combustion engine, having: sensor means and / or display means for receiving at least one operating parameter decisive for oil consumption; Calculation means for deriving criteria for oil replacement from the operating parameters; communication means for outputting information related to oil replacement based on the criteria. The invention also relates to a computer program product and an internal combustion engine. Background technique [0002] Oil change intervals are usually fixedly specified by the manufacturer of the internal combustion engine, for example as...
