Abstract
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.
Highlights
Alternative fuel resources will play an important role in replacing the dwindling world supply of fossil fuels
We investigated the performance of waste cooking oil methyl ester (WCOME) as an alternative biofuel in a four-stroke, fourcylinder, direct injection diesel engine
The changes in the energy utilization factor seem to be a function of load rather than engine speed and WCOME content
Summary
Alternative fuel resources will play an important role in replacing the dwindling world supply of fossil fuels. Different ratios of biodiesel are Edited by Xiu-Qin Zhu. University, Konya, Turkey blended with fossil fuel for use in diesel engines, which are recognized for energy generation and are a power source providing higher efficiency and ruggedness in the field of transportation. The performance of biodiesel-fueled engines is better than that of diesel-fueled engines in terms of thermal efficiency, brake-specific energy consumption, and smoke opacity, wear of vital components and exhaust emissions for an entire range of operations (Agarwal and Das 2001). These findings are supported by researchers who observed similar behavior for all biodiesel blends with fuel of various
