Abstract
Various methods and systems are provided for detecting particles generated from engine component degradation within an engine system. In one embodiment, a method for an engine comprises indicating engine degradation in response to a buildup of particles in a magnetic field, the magnetic field positioned in a flow of gas.
Claims20
A method, comprising:
- applying a magnetic field within a gas flow passage through which a gas flow passes, the gas flow including at least some exhaust gas;
- and
- measuring a signal produced by particles in the gas flow interacting with the magnetic field.
A method, comprising:
- indicating engine degradation of an engine in response to a buildup of particles in a magnetic field, the magnetic field positioned in a flow of gas through a gas flow passage of the engine.
A system, comprising:
- an engine;
- a flow passage coupled to the engine for passage of a gas flow comprising at least some exhaust gas;
- a device configured to generate a magnetic field positioned in the flow passage for attracting particles traveling in the flow passage;
- a detection circuit electrically coupled to at least one of the device or an electrode and configured to produce a signal responsive to presence of the particles between the device and the electrode;
- and
- a controller configured to indicate engine degradation when the signal from the detection circuit is indicative of the particles being present in an amount above a threshold level.
