Abstract: The present work focuses on the experimental study of multi-cylinder DI diesel engine using diesel-biodiesel-ethanol based fuel blends. The blends contain diesel, biodiesel and alcohol are 60:30:10% on a volume basis. The measured emission was converted into a specific basis and the overall cycle emission was also calculated. The combustion parameters such as cylinder pressure history, maximum pressure and its angle, rate of pressure rise, heat release rate, and angle of 5, 10, 50, and 90% mass burning were compared. A little lower peak pressure was observed for hybrid fuel blends (< 7%), the premixed heat release was lower than diesel fuel whereas the diffusion stage heat release rate was higher. The lower rate of pressure rise for hybrid fuel blends shows its suitability in diesel engines in terms of combustion noise, higher thermal efficiency, lower specific and cyclic emissions, than diesel expect unburned hydrocarbon in the exhaust.
