Whilst discussing spark-ignition knock, Heywood [15] points out that due to the highly variable nature of engine knock, fundamental definitions of knock intensity is extremely difficult to make.
The system also has the ability to compute, in real-time, additional individual cycle combustion parameters such: as IMEP, PMEP and NMEP; misfires; peak pressure, maximum rate of pressure rise and locations; polytropic coefficients of expansion and compression; upper, lower and average pressure envelopes; injector start and duration, both crank angle and time; mass burn fraction and rate; engine averages of IMEP, NMEP, peak pressure, maximum rate of pressure rise and their location; and knock intensity and peak.
