Abstract
The objective of this study is to obtain an insight inside the combustion chamber of a Diesel engine running with a blend containing 90 % v/v Diesel and 10 % v/v Ethanol (D90E10) compared to pure Diesel (D100) operation. Since the experimental conditions are kept the same for both cases the simulation boundary conditions are almost identical. Following the calibration of the model and the analysis of in-cylinder images it was noted that the start of injection for the D90E10 case is slightly advanced while the total duration remains the same. Combined with an improved combustion this led to higher in-cylinder pressure and temperature values which increased the NO emissions. However, the soot emissions reduced.
