| 摘要 |
Systems (8) and methods (100) for estimating an engine event location are disclosed herein. In one embodiment, a controller (25) is configured to receive (104) a signal from at least one knock sensor (23) coupled to a reciprocating engine (10), transform (106) the signal, using a multivariate transformation algorithm, into a power spectral density (108), transform (114) the power spectral density into a plurality of feature vectors using predictive frequency bands (112), predict the engine event location using at least the plurality of feature vectors and a predictive model, and adjust operation of the reciprocating engine based on the engine event location. |
