Abstract

A system includes at least one sensor for sensing at least one of vibration, pressure, acceleration, deflection, or movement within a reciprocating engine and a controller. The controller is configured to receive a raw signal from the at least one sensor, derive a filtered knock signal using predictive frequency bands by applying a filter, derive an absolute filtered knock signal from the filtered signal, identify a maximum of the absolute filtered knock signal for each engine cycle, predict a peak pressure value of each of one or more engine cycles using the identified maximums of the absolute filtered signal and a predictive model, and adjust operation of the reciprocating engine based on the predicted peak pressure values.
