“…Furthermore, there are some drawbacks regarding the use of biodiesel due to its lower heating value, and higher density, viscosity, fuel consumption, and NOX emissions compared with traditional fuels. Thus, the inclusion of additives in fuel blends becomes an essential topic in order to minimize these drawbacks (Rashedul, et al, 2014).…”

A lumina nanoparticles were synthesized by sol-gel method and submitted to thermal treatment at 750 and 1000 °C. X-ray diffraction was used to determine crystal formation with sizes up to 280 nm. To achieve stable suspensions, a nano-additive was mixed with the diesel/biodiesel blends along with oleic acid surfactant to obtain concentrations of nano-additives at 10 and 20 ppm. For this, alumina nanoparticles were firstly mixed with 20 mL of oleic acid by using an ultrasonicator. Then, this mixture was heated at 80°C under constant agitation for 1 hour, and it was subsequently submitted to ultrasound for 30 minutes. Colloidal stability was evaluated according to Deryaguin-Landau-Verwey-Oberbeek (DLVO) theory by analyzing the total interaction energy of the system. Effects on the kinematic viscosity and flash point of the B10 blend were determined according to ASTM D-445 and ASTM D-93 regulations. The application of nano-additives in biodiesel blends showed an increase of the kinematic viscosity from 2.75 cSt to 3.33 cSt at 40°C with 20 ppm of nanoparticles in the B10 blend, while flash point increased from 65 °C to 66 °C. These results could represent a beneficial effect for engines performance due to their better lubricant capacity. On the other hand, fuels with high enough flash point are easy to handle for transportation and storage. Then, the implementation of nano-additives represents a good opportunity for the biofuels industry. ABSTRACTHow to cite: Herrera, Adriana., Ojeda, K.A., Peñaloza, A.D. Rincón, A.

Abstract-Biodiesel has been a promising clean alternative fuel to fossil fuels, which cuts the emissions that are released by fossil fuels, and perhaps reduces the energy crisis induced by the exhaustion of oil resources in the near future. In this study, the effect of antioxidant additive on engine performance and emission characteristics of an engine fueled with palm biodiesel was investigated and compared with conventional diesel fuel. For this study, four fuel samples including pure diesel, diesel-biodiesel (B20), diesel-biodiesel-additive (B20+additive) and pure biodiesel (B100) were used in a multi cylinder, four stroke, water cooled, direct injection diesel engine. Engine tests were performed at various engine speed of 1000 rpm to 4000 rpm with 50% throttle opening. Engine performance and emission concentrations are investigated by determining the break specific fuel consumption (BSFC), brake thermal efficiency, CO, HC, NO x and smoke opacity using gas analyzers. The results showed that the use of baynox plus solution as additive with palm methylester gave average 3.10% higher brake power as well as 23.2% and 2.40% lower NO x and brake specific fuel consumption than the biodiesel blend without additives.Index Terms-IC engine, palm methyl ester, additives, NO x . I. INTRODUCTIONThe need for energy remains to increase worldwide, creating a need to branch out from conventional fossil fuels [1], [2]. The global energy requirement is anticipated to increase about 30% in the decades between 2010 and 2030 [3], [4]. Increased environmental concern, tougher vehicle emission norms, increasing prices and uncertainties concerning petroleum availability necessities the search of a viable alternative fuel, which is more environmental friendly [5]- [7]. In recent years, there has been an increased emphasis on extending the role of alternative fuels. Aside from reducing dependency on fossil fuels, a lot of the effort to increase the utilization of alternative fuels has been prompted by the importance of reducing greenhouse gases emissions, such as carbon dioxide, in reaction to the increasing menace of global warming [8]-[10]. Biodiesel is a promising alternative fuel, which is renewable, biodegradable, non-toxic and environmental friendly [4], [11], [12]. It is an ester based oxygenated fuels consisting of a long chain fatty acid and can be derived from vegetable oils (both edible and non-edible), waste cooking, and animal fats oil etc. [13]. Biodiesel in Manuscript received June 10, 2015; revised December 10, 2015 Lin and Rong [20] investigated the effect of waste cooking oil biodiesel, fish oil biodiesel and 2D diesel on a 4-cylinder direct injection engine. They observed higher NO x and PM emissions and lower CO emission while using fish oil biodiesel than using waste cooking oil biodiesel. However, both biodiesels showed lower PM, CO emission and higher NO x emissions compared to diesel fuel. The fish oil biodiesel gave lower BSFC than to the waste cooking oil biodiesel. Behç et [21] carried out an experiment to ...

“…The increase in need for petroleum fuels and also the fast depletion has forced the researchers for investigating new methods to reduce emission and improve the performance of the prime movers. Due to the depletion of petroleum product and the continuous increase in cost, it is the urgent need to develop alternative fuels especially to diesel oil 1 . Diesel engines have the advantages of high thermal efficiency lower emission of CO and HC.…”

Diesel engines have been widely used for better efficiency and low emissions, but diesel engine produces more smoke, particulate matter and oxides of nitrogen and reducing all these emissions simultaneously is not possible as on today due to trade of between oxides of nitrogen and smoke. Engines emission can be decreased by employing fumigation. Using fumigation process emission composition can be reduced when compared to normal operation. In this work an attempt has been made to reduce oxides of nitrogen, hydrocarbon and carbon monoxide using methanol fuel in the combustion chamber. The chemical behaviors and reactions of methanol over hydrocarbons also analyzed. A single cylinder four stroke, 5hp, direct injection, engine test rig was used for experiment purpose. From the experimental analysis, it was found that alcoholic fuels can effectively be used in diesel engines with methanol fumigation using EFI kit that normally operates at high power outputs. The result shows that brake thermal efficiency is slightly decreased when compared without modification at all flow rates.
