Piezo-electric pressure transducers may be installed inside the spark-plug to monitor the pressure signal in the combustion chamber. The advantages of the technique are reviewed and the biggest ...

It’s a busy screen, but it was produced from just three signals; a blue crankshaft sensor waveform, a green fuel pressure waveform, and a red waveform that indicated when cylinder one fired. The ...

This paper addresses issues associated with the measurement and analysis of crank angle based cylinder pressure to obtain accurate knock data. Issues examined include knock model features, the effect ...
