KNOCK-INDUCED CAVITY RESONANCES IN OPEN CHAMBER DIESEL ENGINES

Knock causes acoustical cavity resonances in the combustion chambers of engines. Understanding this phenomenon is important for control of engine noise and optimization of knock-detection systems. Cavity resonances were studied in detail for six open-chamber diesel engines of different sizes. Spectal data were obtained from cylinder pressure-time traces and compared with predictions from finite-element calculations of the cavity resonances. Good agreement was found.
