Combustion Stability, Performance and Emission Characteristics of a CI Engine Fueled with Diesel/n-Butanol Blends

The development of compression ignition engines depends mainly on using alternative fuels, such as alcohols. paper presents the results tests a stationary engine fueled with mixtures diesel oil and n-butanol an energy share from 0 to 60%. combustion emission dual-fuel were compared conventional diesel-only engine. As part work, process, including changes in pressure heat release rate, well exhaust emissions test engine, investigated. main operational parameters determined, mean indicated pressure, thermal efficiency specific consumption. Moreover, stability operation was analyzed. research shows that 60% addition fuel increases delay (by 39%) shortens duration 57%). In addition, up 40%, it increased pmax, HRRmax PPRmax. characterized by highest efficiency, equal 41.35% when operating DB40. whole range alcohol content, stable. With increase content NOx increased. lowest concentration CO obtained during DB50. After initial (for DB20), THC reduced value for Increasing resulted significant, more than 43 times, reduction soot emissions.
