Abstract
A computer-implemented platform may comprise hardware and software configured to manage an engine using knock intensity data. Knock intensities from a plurality of combustion cycles may be used to estimate a statistical distribution of knock intensities. The distribution of knock intensities may be used to determine a Descriptive Statistic, which may represent a state of tune of the engine. A calculated Descriptive Statistic may be compared to a desired Descriptive Statistic (e.g., that is representative of operation during a desired tune state of the engine). A deviation between the calculated and desired knock intensity distributions (e.g., between the calculated DS and desired DS) may be used to adjust a control parameter of the engine. Adjustment may be engine-wide. Adjustment may be cylinder-by-cylinder.
