Abstract:
A HCCI engine with a model reference adaptive feedback control system maintains stable HCCI combustion during speed/load transitions by: (1) estimating the maximum rate of pressure rise (MRPR), for each cycle, from an extra-cylinder sensor metric, such as a crankshaft dynamics or knock sensor metric, via statistical vector-to-vector correlation; (2) periodically self-tuning the vector-to-vector correlation; (3) applying knowledge base models to guide cycle-to-cycle adjustments of fuel quantity and other engine parameters, to maintain a target MRPR value.
