Abstract

Abstract: The ever-growing use and expense of fossil fuels have prompted the planet to quest for alternatives to environmental issues. Efforts are being made worldwide to extract alternative fuels from more than 400 plant species for both edible and non-edible oils. Being edible oils consuming by the human race, this paper concentrated on non-edible deep-fried oil rather than fresh vegetable oils. Deep-Fried Oil (DFO) was considered as non-edible oil because poor quality to re-use the same. However, direct use of DFO in an engine domain remains a significant challenge due to its high viscosity and low heat value. This investigation deals with this problem through synchronous DFO pre-heating with the waste heat recovery framework. Experimental research was carried out on a 4-stroke, constant speed, water-cooled, IDI compression ignition engine with a power of 9.85 hp. The effect of the pre-heating of DFO was tested at various temperatures ranging from 60 °C to 130 °C for performance, combustion and emissions. Further, 130 °C shown improved efficiency, which is nearby diesel and a marginal rise in pollution was observed. Highlights: Sunflower Oil based Deep Fried Oil (DFO) is identified as a novel feed stock. Preheating the DFO to 130 °C shown performance nearby diesel operation. Performance, emissions and combustion analysis was carried out. FFA analysis was carried out on virgin sunflower oil and sunflower oil based DFO and discussed. Combustion analysis instrumentation associated with IDI CI engine was discussed.
