Investigations on In-Cylinder Pressure Cycle-to-Cycle Variations in a Diesel Engine by Recurrence Analysis 2015-01-0875

In this paper we have obtained real-time series of in-cylinder pressure by carrying out some experiments and studied the in-cylinder pressure cycle-to-cycle variations in a diesel engine. By using recurrence plot (RP) and recurrence quantification analysis (RQA), we have investigated the dynamical characteristics of combustion in diesel engine through the in-cylinder pressure cycle-to-cycle variations. The results show that the combustion process exhibits many chaotic features and deterministic nature, the qualitative and quantitative change in combustion can be easily related to patterns in recurrence plots (RPs) and RQA, and combustion system is sensitive to initial conditions. The conclusions of our research work may be helpful in developing effective control strategies to improve diesel engine performance.
