In this study, blends of soybean oil ethyl ester (SOEE) and diesel fuel are tested as alternative fuel in a single cylinder, air cooled pre-combustion chamber diesel engine at different speeds and their effects on engine performance and emissions are analyzed. It is observed that the average moment obtained by 5% SOEE (B5) is 0.53% lower, the level of power obtained is 1.8% lower; however, specific fuel consumption is approximately 4.31% higher than those of diesel fuel. In the experiments conducted with 20% SOEE (B20), it is observed that the average moment is 1.74% lower, the level of power obtained is 5.91% lower; however, specific fuel consumption is approximately 10.94% higher than those of diesel fuel. Moreover, while a distinctive decrease is observed in CO emissions of fuel blends, NOx emissions are obtained very close to that of diesel fuel.

“…This could be attributed to the presence of TGs in CTO. Similar results were reported in the literature [31][32][33][34]. The CTO sample had a high amount of linoleic acid (46.24%) as compared to most of the reported results in the literature.…”

Abstract:The primary objective of this work was to investigate the thermal and rheological properties of crude tall oil (CTO), a low-cost by-product from the Kraft pulping process, as a potential feedstock for biodiesel production. Adequate knowledge of CTO properties is a prerequisite for the optimal design of a cost-effective biodiesel process and related processing equipment. The study revealed the correlation between the physicochemical properties, thermal, and rheological behavior of CTO. It was established that the trans/esterification temperature for CTO was greater than the temperature at which viscosity of CTO entered a steady-state. This information is useful in the selection of appropriate agitation conditions for optimal biodiesel production from CTO. The point of interception of storage modulus (G ) and loss modulus (G ) determined the glass transition temperature (40 • C) of CTO that strongly correlated with its melting point (35.3 • C). The flow pattern of CTO was modeled as a non-Newtonian fluid. Furthermore, due to the high content of fatty acids (FA) in CTO, it is recommended to first reduce the FA level by acid catalyzed methanolysis prior to alkali treatment, or alternatively apply a one-step heterogeneous or enzymatic trans/esterification of CTO for high-yield biodiesel production.

“…Many studies have been conducted on the use of alternative input products such as rape seed and soybean WCOME in the production of biodiesel for use in diesel engines (Altıparmak et al 2007;Felizardo et al 2006;Kaplan et al 2006;Mangesh and Dalai 2006;Nachid et al 2015;Selvan and Nagarajan 2013;Ulusoy et al 2004Ulusoy et al , 2016. The performance and smoke results obtained from an electricity generator engine operating on WCOME showed that the smoke reduction, compared to that of conventional diesel fuel, was around 60% for B100 (100% biodiesel) and around 25% for B20 (20% biodiesel) .…”

Investigation of performance and emission characteristics of waste cooking oil as biodiesel in a diesel engine

et al. 2018

View full text Add to dashboard Cite

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.
