| Abstract: | An experimental investigation on the equilibrium monitoring of cylinder working process for a marine diesel engine was carried out. The properties of cross-correlation function, cross-power spectrum and coherence function between cylinder pressure signals are described. Relationships between these functions and engine working conditions are given and a equilibrium monitoring method of engine working process using correlation analysis technique is proposed. |
