AB - The purpose of this research work is to build a multiple linear regression  model for the characteristics of multicylinder diesel engine using  multicomponent blends (diesel- pungamia methyl ester-ethanol) as fuel. Nine  blends were tested by varying diesel (100 to 10% by Vol.), biodiesel (80 to  10% by vol.) and keeping ethanol as 10% constant. The brake thermal  efficiency, smoke, oxides of nitrogen, carbon dioxide, maximum cylinder  pressure, angle of maximum pressure, angle of 5% and 90% mass burning were  predicted based on load, speed, diesel and biodiesel percentage. To validate  this regression model another multi component fuel comprising diesel-palm  methyl ester-ethanol was used in same engine. Statistical analysis was  carried out between predicted and experimental data for both fuel. The  performance, emission and combustion characteristics of multi cylinder diesel  engine using similar fuel blends can be predicted without any expenses for  experimentation.
