“…It is observed that the SB causes a 15% increase in NOx emissions. This is a common behavior that has been reported in different types of biodiesel [48]. However, the presence of water allowed the reduction of NOx emissions.…”

This study evaluates the influence on the combustion process, fuel consumption, and polluting emissions in a diesel engine, which operates with biodiesel from soybean oil and water emulsions with percentages of 4% and 8%. For this study, a stationary diesel engine operating at four different torque conditions and a fixed rotation speed of 3400 rpm is used. Test fuels are diesel, soybean oil biodiesel, and SB4W and SB8W water emulsions. The results indicate that SB4W and SB8W cause a 6% reduction in calorific value and an 18% and 1% increase in viscosity and density. However, the presence of water in biodiesel can help reduce engine BSFC by 8%. The SB4W and SB8W allow a 23% reduction in NOx emissions. With the use of SB4W fuel, a reduction of 16%, 29%, and 14% in CO, HC, and smoke opacity is obtained compared to soybean oil biodiesel. The maximum inclusion of 8% water in soybean oil biodiesel is recommended since a higher percentage can cause the presence of incomplete combustions.

“…Biodiesel in a diesel engine (compression-ignition engine) has reduced exhaust gas density but increase fuel consumption because the combustion heating value of biodiesel lower than petrodiesel [5], [6]. Biodiesel exhaust gas has contained more nitrogen oxides NOx, but unburned hydrocarbons (HC), carbon monoxide (CO) are lower than petrodiesel [7]- [11]. Nano metal oxide additives have been used to improve the characteristics of biodiesel.…”

Nano γAl2O3 has been one of the nanometal oxides that has improved the characteristics of biodiesel. The effect of γAl2O3 nanoparticles addition on premixed flame combustion is investigated with an experiment on the laminar flame speed of Calophyllum inophyllum methyl ester 30% and 70% petrodiesel mixtures, at atmospheric pressure and preheated temperature T = 473K. The γAl2O3 nanoparticles added to CIME30 biodiesel were 0ppm, 100ppm, 200ppm, and 300ppm. Experiments were carried out on a bunsen burner. The equivalent ratio of the mixture between ϕ = 0.67 to 1.17. Experiments revealed that the addition of nanoparticles to CIME30 biodiesel expands the flammability limit and increases the laminar flame speed. CIME30 without nanoparticles, flame stable between ϕ = 0,76 -1,17. CIME30 with nanoparticles, flame stable between ϕ = 0,67 -1,17. Combustion of CIME30 required a lot of air. The highest laminar flame speed occurred at the equivalent ratio ϕ = 0.83. The highest laminar flame speed of CIME30 0, 100, 200, and 300 ppm were 30.77, 34.50, 35.90, 38.45 cm/s respectively. The higher the nano γAl2O3 concentration the higher the laminar flame speed. This occurs due to the catalytic effect of γAl2O3 on biodiesel and its mixtures.

“…It may be observed that, at higher CR and load, the smoke opacity of undi‐diesel blends are lower which indicates the presence of sufficient oxygen molecules during the combustion of base fuel. How et al have also observed the similar CO emission for diesel‐undi blends.…”

“…They concluded that, 10% (by volume) Biodiesel blended fuel improves the BTE (by 2.30%), fuel consumption (by 3.06%), CO and smoke opacity of the engine than base line diesel operation. How et al also reported that, diesel‐biodiesel blend reduces the CO, UHC, and smoke emissions of CI engine with the penalties of higher amount of NO X emissions. The lower CO emission with Biodiesel blended fuel has also been stated by Shehata .…”

The present investigation highlights the effect of variable compression ratio (VCR) on the performance and exhaust emission characteristics of a single cylinder, direct injection diesel engine fueled with undi‐diesel blends. 10%, 20%, 30%, 40%, and 50% undi fuel have been added to diesel in volumetric proportions and tested by varying compression ratio (CR) from 16:1 to 20:1. Undi addition to diesel fuel significantly improves the brake thermal efficiency (BTE) and brake specific energy consumption (BSEC) of the engine. In addition, higher CR facilitates to improve unburned hydrocarbon (UHC), carbon monoxide (CO) and smoke opacity of the diesel engine with the penalties of higher oxides of nitrogen (NOX) emissions. In perspective of the engine experimental outputs, a Taguchi assisted Fuzzy based trade off study has been conducted to screen and locate the optimal diesel engine operating conditions, namely, CR, undi share, and load. The optimum process parameter has been found to be A2B6C2 with a multi performance characteristics index (MPCI) value of 0.683 indicating the optimum operating conditions of 17:1 CR, 50% (by volume) undi share at 50% load.
