Abstract | Bio-butanol is a potential fuel for compression ignition engines (CI) because of its beneficial physicochemical properties and its ability to be produced from agricultural waste through fermentation. The feasibility of using bio-butanol from biomass is not yet clear due to the high production cost caused by low yields and expensive processes for separating it from butanol-acetone (BA) fermentation. Instead using the intermediate fermentation products of butanol (that is BA) as a fuel has already been found to produce clean combustion. Butanol-acetone is, therefore, proposed as a fuel for CI engines which could lead to extra reductions in BA production cost, and could improve combustion by reducing temperature. Butanol produces in four isomers: n-butanol, iso-butanol, sec-butanol, and tert-butanol. The effects of iso-BA-diesel blends on combustion, performance and emission characteristics were investigated at three engine speeds and full load. The results were compared with neat diesel and 10% and 20% iso-BA-90% diesel blends. Brake power (BP) was slightly reduced while Brake specific fuel consumption (BSFC) increased for iso-butanol-diesel blends due to the low heating value. Exhaust gas temperature (EGT) and Nitrogen of oxide (NOx) emissions were reduced with the inclusion of iso-butanol in the test blends, relieving combustion and reaction temperature which resulted in NOx emissions reduction. Carbon monoxide (CO) emissions were reduced due to the high oxygen content. However, unburnt hydrocoroubn (UHC) emissions rose due to iso-BA-diesel blend showing higher UHC because iso-butanol has the most terminal C single bond H bonds, so the reaction rate of iso-butanol in butanol-acetone is lower, resulting in insufficient time to complete the reaction, causing an increase in UHC emissions. Thus, iso-butanol-acetone could be a good alternative fuel for CI engines because of its production manner and reduced emissions. |
