“…However, increases of 8.5% and 32% were observed in specific fuel consumption and NOx emissions, respectively. Murillo et al (2007) tested a four-stroke diesel outboard engine running on conventional diesel, conventional diesel blended with 10%, 30% and 50% biodiesel derived from WCOME and pure biodiesel. The biodiesel blends proved to be environmentally friendly alternatives to conventional diesel fuel.…”

Biodiesel is one of the most popular prospective alternative fuels and can be obtained from a variety of sources. Waste frying oil is one such source along with the various raw vegetable oils. However, some specific technical treatments are required to improve certain fuel properties such as viscosity and calorific value of the biodiesel being obtained from waste cooking oil methyl ester (WCOME). Various treatments are applied depending on the source and therefore the composition of the cooking oil. This research investigated the performance of WCOME as an alternative biofuel in a four-stroke direct injection diesel engine. An 8-mode test was undertaken with diesel fuel and five WCOME blends. The best compromise blend in terms of performance and emissions was identified. Results showed that energy utilization factors of the blends were similar within the range of the operational parameters (speed, load and WCOME content). Increasing biodiesel content produced slightly more smoke and NOx for a great majority of test points, while the CO and THC emissions were lower.

“…The engine power and torque have increased at all engine speeds. Despite the low heating value of F 2 0 proportion to diesel, it has seen that the torque and power have slightly decreased with pure diesel(F0).The similar results of decreased power and torque were achieved by using biodiesel [6], [7] and ethanol [8]. The oxygen content of fusel oil represents one of the main reason to improve the in-cylinder combustion reactions, despite the higher water content (13.5%) of fusel oil and lower heating value.…”

Abstract-In order to reduce the dependency on fossil oil energy resources, the using of several energy resources in compression-ignition engine has been the target of attention of researchers. The major renewable alternative combustible species are methanol, biogas, ethanol, biodiesel, and hydrogen. Fusel oil is a by-product of bioethanol production during the fermentation process present one of the new alternative fuels for compression-ignition engine. The aim of this work is to experimentally investigate the effect of fusel oil -diesel blending on performance and emission in single cylinder compression ignition engines. The test achieved under 25 % engine load at five-engine speed 1200 to 2400 rpm with intervals of 300 rpm. The experimental results revealed that the engine indicted power and torque slightly decrease for F 2 0 compared with pure diesel, and the increment was happened in fuel consumption. Although diesel fuel yields, the highest volumetric efficiency and exhaust temperature. Moreover, the results showed CO 2 and CO were increased while the NOx emissions decrease with the use F 2 0. All the negative effects that happened in power and torque was because of the water content, low heating value, low cetane number for fusel oil.Index Terms-Fusel oil, NOx emissions, single cylinder engine, alternative fuels, engine performance.I.

“…This can be a great guide in designing biodiesel engines. Higher thermal efficiency with pure biodiesel was reported by Murrilo et al (2007). Gogoi and Baruah (2010) found that blends B20, B40 and B60 present an increase in thermal efficiency compared to diesel.…”

Because of environmental problems, it becomes necessary to develop alternative fuels that give engine performance at par with diesel. Among the alternative fuels, biodiesel and its blends hold good promises as an eco-friendly and the most promising alternative fuel for Diesel engine. The properties of biodiesel and its blends are found similar to that of diesel. Many researchers have experimentally evaluated the performance characteristics of conventional Diesel engines fueled by biodiesel and its blends. However, experiments require enormous effort, money and time. Hence, via finite-time thermodynamics simulation, an air-standard Diesel cycle model with heat transfer loss and variable specific heats of working fluid is analyzed to predict the performance of Diesel engine. The effect of compression ratio, cut-off ratio and fuel type on output work and thermal efficiency is investigated through the model. The fuels considered for the analysis are conventional diesel, rapeseed oil biodiesel and its blend (20 % biodiesel and 80 % diesel by volume). Numerical simulations showed that the output work and thermal efficiency of the engine decrease with increase of cut-off ratio for all fuels. Also, the model predicts similar performance with diesel and biodiesel blend which means that the biodiesel blend (20 % biodiesel and 80 % diesel by volume) could be a good alternative and eco-friendly fuel for conventional Diesel engines without any need to modify the engine.
