In this work, experimental investigations are carried out to evaluate the performance and efficiency of a biodiesel-fuelled engine. The tests were conducted on a direct-injection compression ignition engine, equipped with two acquisition stations, one for measuring high frequency signals (e.g. in-cylinder pressure), the other for measuring low frequency signals (e.g. engine speed). Then, thermodynamic analysis of the data were implemented to calculate the heat release rate and to estimate the losses of heat. The results exhibit that the WCO biodiesel presents a comparable performance to those of standard diesel fuel. The biodiesel combustion is much rapid which leads to a slight reduction in NOx emissions. Furthermore, the presence of oxygen in biodiesel molecule conducts to more complete combustion and reduces the pollutant emissions of the engine.
