ABSTRACT:
Feedback control of an internal combustion engine is performed based on a signal from a vibration sensor and a crankshaft angle sensor. An energy factor can be computed based on these sensor signals. A vector of energy factor can be computed as a function of crank angle degree over a particular window of engine rotation of interest. Based on the energy factor vector, combustion phasing can be estimated.
