Modeling and Energy Analysis of a Diesel and Biodiesel Fuelled Engine

Modeling has been used to investigate the combustion performance of a single cylinder direct injection diesel engine fueled by biodiesel like cotton seed oil. The focus of the present study is to review the different available model used for modeling of CI engines. The modeling of CI engine is divided into single zone, multizone and multi-dimensional model. The model evaluation is made based on the time complexity, space complexity, and prediction accuracy using the developed computer program like MATLAB. Our focus is on single zone model which further subdivided in many submodel i. e. heat release rate, heat transfer, ignition delay period, droplet evaporation, intake and exhaust flow and combustion model. The numerical simulation was performed with the standard specification of a CI engine by using MATLAB software with least time.
