Abstract
The disclosure provides a method and a device for determining the engine oil quality of an internal combustion engine. The engine oil quality is determined by evaluation of the switching times of an oil pressure switch of the internal combustion engine after a starting operation of the internal combustion engine.
Claims20
A method for determining engine oil quality of an internal combustion engine, the method comprising:
- evaluating switching times of an oil pressure switch of the internal combustion engine after a starting operation of the internal combustion engine.
A device for determining engine oil quality of an internal combustion engine, the device comprising:
- an engine controller;
- and
- an oil pressure switch, wherein after a starting operation of the internal combustion engine, the oil pressure switch transmits binary switching information to the engine controller when a specified pressure threshold is exceeded causing the engine controller determines the engine oil quality by:
- evaluating the switching times of the oil pressure switch.
