Abstract
Method for monitoring a lubricant of a combustion engine, wherein measured numerical values are acquired with at least one sensor over a running time of a combustion engine, wherein the measured numerical values are representative of an oil quality of an engine oil of the combustion engine, wherein an oil sampling interval is adapted depending on at least one measured numerical value and/or a variable derived therefrom.
Claims23
A method for monitoring a lubricant of a combustion engine, comprising:
- acquiring a plurality of measured numerical values at a measurement frequency in a range between 0.5 Hz and 3 Hz with at least one sensor at the combustion engine over a running time of the combustion engine, wherein the measured numerical values are representative of an oil quality of an engine oil of the combustion engine;
- and
- adapting an oil sampling interval for analysis of the engine oil away from the combustion engine in a laboratory depending on at least one measured numerical value of the plurality of measured numerical values and/or a variable derived therefrom, wherein adapting the oil sampling interval comprises:
- shortening the oil sampling interval when the at least one measured numerical value or the variable derived therefrom indicates the oil quality is less than expected;
- and
- lengthening the oil sampling interval when the at least one measured numerical value or the variable derived therefrom indicates the oil quality is greater than expected.

A system, comprising:
- a controller configured to:
- acquire a plurality of measured numerical values at a measurement frequency in a range between 0.5 Hz and 3 Hz with at least one sensor at a combustion engine over a running time of the combustion engine, wherein the measured numerical values are representative of an oil quality of an engine oil of the combustion engine;
- and
- adapt an oil sampling interval for analysis of the engine oil away from the combustion engine in a laboratory depending on at least one measured numerical value of the plurality of measured numerical values and/or a variable derived therefrom, wherein the controller is configured to adapt the oil sampling interval by:
- shortening the oil sampling interval when the at least one measured numerical value or the variable derived therefrom indicates the oil quality is less than expected;
- and
- lengthening the oil sampling interval when the at least one measured numerical value or the variable derived therefrom indicates the oil quality is greater than expected.
4 more elements
A system, comprising:
- a combustion engine having an oil circuit and at least one sensor along the oil circuit;
- a controller configured to:
- monitor the at least one sensor to obtain sensor feedback at a measurement frequency in a range between 0.5 Hz and 3 Hz, wherein the sensor feedback or a variable derived therefrom indicates an oil quality of an engine oil of the combustion engine;
- and
- adapt an oil sampling interval for analysis of the engine oil away from the combustion engine in a laboratory based on the sensor feedback or the variable derived therefrom, wherein the controller is configured to adapt the oil sampling interval by:
- shortening the oil sampling interval when the sensor feedback or the variable derived therefrom indicates the oil quality is less than expected;
- and
- lengthening the oil sampling interval when the sensor feedback or the variable derived therefrom indicates the oil quality is greater than expected.
