Vegetable oils as fuel have received attention in recent years due to their advantages including renewable nature and domestically produced energy resources. Achieving reduced emission is important subject, as it enhances sustainability of biofuels. General factorial experimental design and analysis of variance (ANOVA) is used to analyze how NOx emission is influenced by alcohol content in vegetable oil-diesel fuel blends. Fuel samples 20% croton oil -80% diesel (20%CRO-80%D2), 15% croton oil -5% 1-butanol -80% diesel (15%CRO-5%BU-80%D2), and 10% croton oil -10% 1-butanol -80% diesel (10%CRO-10%BU-80%D2) were investigated. Four-cylinder compression-ignition (CI) engine was run at constant speed 3000 RPM, loaded at different loading conditions: low idle as 0 to 100% load condition. The specific fuel consumption and exhaust temperature of fuel blend containing butanol was measured. It was observed that nitrogen oxides (NOx) emission decreases as percentage of butanol alcohol content increases in fuel samples.

“…This may be attributed by the high HHV of blend sample containing 0% of butanol. It can be deduced therefore that, addition of more butaol to fuel blends containing croton oil and 80% diesel fuel increases SFC (Karuppasamy et al, 2012;Siwale et al, 2012).…”

The use of biofuels that include n-butanol in diesel fuel (DF) is attracting attention in the search for the reduction of emissions into the environment due to the burning of fossil fuel. The performance and combustion characteristics were evaluated in this study using blends B5, B10, and B20 (B5: 5% n-butanol and 95% DF) in a turbo-charged direct injection compression ignition engine. In the n-butanol diesel studies, a comparison was made with other studies that also included biodiesel in order to determine how suitable n-butanol-diesel blends were to use in internal combustion engines. Combustion characteristics of B20 (n-butanol 20% and 80% DF) improved when the study was compared with a similar study that included 40% biodiesel added to B20. A higher value of the standard deviation for DF than the blends was observed from the standard deviation diagram, indicating a more stable combustion process for the blends than DF. Soot reduction relative to DF at 1500 rpm at 75% load for B05, B10, and B20 mixtures was 55.5, 77.8, and 85.1%, respectively. This reduction is a significant advantage of blending DF with smaller shared volumes of bioalcohol.

“…Butanol (IUPAC) is a colorless, and may irritate the eyes and skin [6]. Lubricity, intersolubility, and corrosive effects of n-butanol have been discussed in our earlier paper [12]. Researchers have carried out studies to determine the effects of n-butanol or isobutanol added to DF on performance characteristics.…”

In this study, n-butanol-diesel blends were burned in a turbo-charged, direct injection diesel engine where the brake thermal efficiency, (BTE) or brake specific fuel consumption, (BSFC) was compared with that of ethanol-diesel or methanol-diesel blends in another study by other authors. The test blends used were B5, B10 and B20 (where B5 is 5% n-butanol by volume and 95% diesel fuel-DF). In this study, the BTE was higher and the BSFC improved more than in the other study. Because of improved BTE with increasing brake mean effective pressure, BMEP, the BSFC reduced, however the increased shared volume of n-butanol in DF increased BSFC. Adding n-butanol in DF slightly derated the torque, brake power output with increasing speed, and caused a fall in exhaust gas temperatures, (EGT) which improves the volumetric efficiency and reduces compression work. Therefore, a small-shared volume of n-butanol in DF fired in a turbo-charged diesel engine performs better in terms of BTE and BSFC than that of ethanol or methanol blending in DF.
