Abstract

Notes on ‘‘A methodology for combustion detection in diesel engines through in-cylinder pressure derivative signal’’ The recent paper by Luja´n et al. [1] considers methods for analyzing the instant variation of the combustion chamber pressure, directly obtained from the electric signal provided by a traditional piezoelectric sensor. The authors claim to have introduced a new alternative for signal processing that, in opposition to the commercial conditioner, directly measures the intensity in the piezoelectric sensor through Uout ¼ Ri ¼ R [...]
