Condition monitoring and diagnostics for internal combustion engines using in-cylinder pressure and acoustic emission

This thesis aims to provide greater understanding of engine operation through the application of in-cylinder pressure and engine structure-borne acoustic emissions, together with advanced data analysis such as cepstrum and principal component analysis. The analysis methods, coupled with the sensors, utilised in this research resulted in improved reliability in the tools and information that will be required in the development of more efficient and reliable engines. This research will be a useful resource for internal combustion engine researchers and industries.
