COMPARATIVE STUDY ON THE USE OF EDIBLE OIL-BASED BIODIESEL BLENDS ON ENGINE PERFORMANCE AND THEIR EMISSIONS
Abstract
Over the past few decades, the growing worry about reducing global oil deposits and the adverse impact on the environment has escalated the need for creating renewable and eco-conscious fuels. In this context, edible oil-based biodiesel is one of the strong candidates. Presently, approximately 84% of global biodiesel production is sourced from rapeseed oil, with sunflower oil accounting for around 13%, palm oil for 1%, and soybean oil and other sources constituting the remaining 2% [1, 2]. Given that over 95% of biodiesel is derived from edible oils, this constitutes a significant proportion [1]. This work compares different edible oil-based (sunflower, soybean, cottonseed, and palm oils) biodiesel blends on CI engine performance. Based on brake power (BP), brake thermal efficiency, and specific fuel consumption, the engine performance was measured experimental at different blending ratios for each biodiesel. Emission gases for different biodiesel at different blending ratios were also measured. Results show that a 16 kg load, soy 10% (Soybean biodiesel with 10% soybean oil blend) shows a higher BP than other biodiesels. At 10% blending, Soybean biodiesel shows 4.81 kW BP which is 6.4% more than the sunflower biodiesel. And also, it is 21.4% more than palm biodiesel and 21.7% more than cottonseed biodiesel at the same blending percentage. Results indicate that the use of different biodiesels influences the chemical composition of emission gases.
