AUTOMOTIVE PIEZOELECTRIC SENSORS FOR SIMPLIFIED KNOCK DETERMINATION
Aromiński A.
pages 52 - 55, full text

A phenomenon of engine knocking is observed when a portion of the air-fuel mixture inside combustion chamber self ignites. Analyzing vibration signal from the flat response piezoelectric sensor located on cylinder block is one of the most popular method that provides sufficient accuracy in knocking determination. Knock sensors used in almost all modern gasoline engines can deliver a signal that is correctly interpreted by an engine control unit (ECU). This is possible due to the research and experience of manufacturers. This paper briefly presents a preliminary concept of using simple, relatively inexpensive automotive piezoelectric knock sensors to determine knock combustion phenomenon in prototype internal combustion engine. Initial" flat response" sensors tests without external amplification devices were conducted. Future research is expected to determine the actual range of using cars sensors for serious measurements.
