Patent ID: 7181339

Claim:
A real-time system for acquiring and presenting, for analytical use, from a subject internal combustion engine, engine-knock data, said system, in operative condition, comprising transducer structure operatively coupled to such an engine, operable, when so coupled, and with the engine operating, to acquire (a) subject-engine-derived, energy-content operating data expected to include subject-engine knock energy data when an engine-knock condition exists in the subject engine, and (b) subject-engine crank-angle data and signal-processing structure operatively connected to said transducer structure for receiving such subject-engine-derived operating data and subject-engine crank-angle data, and operable, when engine-knock data is present in the received subject-engine-derived operating data, and based upon an energy-content, energy-thresholding determination practice, to produce and present an output which focusedly identifies subject-engine knock behavior.
