Abstract
Methods and systems are provided for a lubricant detection device. In one example, a system comprises one or more sensors arranged in an oil flow path for detecting if a particle is in an oil flow. Engine operating parameters are adjusted in response to sensing the particle, wherein the engine operating parameter adjustments are different in response to only a first sensor detecting the particle or to both the first sensor and a second sensor detecting the particle.
Claims20
A system comprising:
- a lubricant passage comprising a particle capturing device arranged between a first sensor and a second sensor;
- and
- a controller with instructions stored on non-transitory memory thereof that when executed enable the controller to adjust engine operating parameters in response to feedback from the first and second sensors.
A vehicle system comprising:
- a lubricant detection device comprising a particle capturing device arranged between a first sensor and a second sensor, the particle capturing device comprising a magnet;
- and
- a controller with instructions stored on non-transitory memory thereof that when executed enable the controller to:
- activate an indicator lamp in response to a particle being sensed by only the first sensor;
- and
- adjust an engine power output in response to the particle being sensed by each of the first and second sensors.

A method comprising:
- sensing a particle is in an oil flow in response to feedback from a first sensor of an oil detection system;
- activating an indicator lamp engine operating parameters in response to the first sensor sensing the particle and a second sensor not sensing the particle, the second sensor arranged downstream of the first sensor relative to a direction of the oil flow, wherein an oil filter is arranged between the first sensor and the second sensor;
- and
- adjusting engine operating parameters to decrease a fuel injection amount in response to the first sensor and the second sensor sensing the particle.
