Abstract
Systems and methods for estimating an engine event location are disclosed herein. In one embodiment, a control system is configured to receive feedback from at least one knock sensor coupled to a reciprocating engine, estimate an engine parameter based at least on the feedback and an Empirical Transform Function (ETF), estimate a location of an engine event based on the engine parameter, and adjust operation of the reciprocating engine based at least on the location of the engine event.
Claims20
A system for estimating an engine event location, comprising:
- a reciprocating engine;
- at least one knock sensor coupled to the reciprocating engine;
- and
- a control system for:
- receiving feedback from the at least one knock sensor;
- estimating an engine parameter of the reciprocating engine based at least on the feedback and an Empirical Transform Function (ETF);
- estimating a location of an engine event based on the engine parameter, wherein the engine event comprises a peak firing pressure of a cylinder of the reciprocating engine;
- and
- adjusting operation of the reciprocating engine based at least on the location of the engine event.
A method for training a control system to estimate the location of peak firing pressure in a reciprocating engine, comprising:
- receiving a plurality of knock signals from a knock sensor coupled to the reciprocating engine;
- receiving a plurality of engine parameter signals from a second sensor of the reciprocating engine;
- determining a plurality of Empirical Transfer Function Estimates (ETFEs), wherein a respective ETFE of the plurality of ETFEs is based at least on a Fourier transform of a respective knock signal of the plurality of knock signals and on a Fourier transform of a respective engine parameter signal of the plurality of engine parameter signals;
- and
- aggregating the plurality of ETFEs to generate an Empirical Transform Function (ETF).
