“…Some studies show that the use of pure biodiesel in vehicle diesel cycle engines reduces the torque and consequently the power generated (MAZIERO et al, 2006;OZSEZEN et al, 2009;BUYUKKAYA, 2010;FIORESE et al, 2011;NIETIEDT et al, 2011) and increases the time consumption and minimum specific consumption (GODESA, et at. 2010;NIETIEDT et al, 2011;REIS et al, 2013;ÖZENER et al, 2014).…”

ABSTRACT:The use of fuels for agricultural Diesel engines cycle, both of mineral origin (Diesel) or vegetable and animal origin (biodiesel) can significantly alter its performance. Therefore, the aim of this study was to quantify the change in torque, power and consumption of agricultural Diesel engine fuel using minerals and vegetables fuels. It was used a tractor power take-off coupled to a magnetic brake dynamometer (for measuring speed and torque for subsequent calculation of power), and a flow meter (for measuring the hourly fuel consumption and specific fuel consumption calculation). Eleven different fuels (S10 mineral diesel with 5%, 10%, 15%, 20% and 50% biodiesel and mineral diesel S500 with 5%, 10%, 15%, 20% and 50% biodiesel, have been used pure biodiesel B100). The results indicate that the increase of biodiesel in mineral diesel reduces torque and power, increases the specific fuel consumption and practically does not change the hourly consumption. This reduction in torque and power occurs with greater intensity in Diesel S10. Additions of 10% biodiesel in mineral diesel reduces the maximum torque 1.65 Nm (0.6%), the maximum power at 0.33 kW (0.6%) and increases the specific fuel consumption of 3.6 g kWh -1(1.3%).

“…[1] showed that the use of the diesel/biodiesel blend presented reduction of 28-46% of CO, but an increase between 6.95-17.62% of NOx compared to pure fossil diesel. [4] found that a binary mixture (30% Farnesane/70% fossil diesel) reduces CO emissions, but presents similar NOx emissions compared to the pure fossil diesel.…”

Biofuels have been widely used in conventional Diesel engines to replace, partially or totally, by fossil diesel. However, the use of an innovative fuel should be evaluated and an important feature to be considered is the ignition delay of the combustion process. Ignition delay can be correlated with activation energy (Ea) and greatly affects the performance of the engine, including pollutant emissions. This study presents the determination of activation energy of three pure fuels -farnesane, biodiesel and fossil fuel -and their blends. In addition, the correlation between Ea and NOx and CO emissions were established. Gases emissions were generated in the OM 926 LA CONAMA p7/EURO 5 diesel engine according to the European Stationary Cicle (ESC). Activation energies were determined by means of thermogravimetric experiments and the mathematic model free-kinetics. Our results indicate that when biodiesel is added to the blend with fossil Diesel, both activation energy values and NOx emission increase, but no direct correlation between Ea and CO emissions was observed. A contrary behavior was observed with farnesane in the blend, i.e., its addition in the fossil Diesel decreases both activation energy and NOx and CO emissions.

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 ...
