Sustainable Energy Solutions from Water Hyacinth Bioethanol Blends in Diesel Engines with Nano-Coated Pistons

The synthesis of bioethanol from water hyacinth has been of great assistance in re-establishing ecological balance as
fuel alternate. In terms of both financial and ecological considerations, bioethanol is the best raw material from which to create biodiesel. The low thermal conductivity of nano ceramic coatings makes them useful as thermal barrier
coatings in many engineering applications. An aluminum alloy piston sprayed with partly stabilized zirconia ceramic
coating is shown to increase the working performance of engines. The use of oxygenated fuels and nano coating appears to be a practical solution to the problem of hazardous engine emissions. This study provides a comprehensive analysis of bioethanol as a potential substitute fuel for diesel engines, with the aim of achieving energy recuperation from water hyacinth. This paper investigates the performance and emission characteristics of the bioethanol blends derived from
water hyacinth in the nano-coated piston diesel engine. Bioethanol blends consumed 1.1% to 11.3% more fuel than
diesel. All bioethanol blends produced more carbon monoxide and hydrocarbon emissions than the diesel engine,
around 2.4%–15% and 2.6%–16%, respectively, at varying loads. Blends of BE10D90 and BE20D80 show that
increasing oxygen content reduces smoke and NOx by 4%–9.3% and 1.9%–7.4%, respectively, when compared to diesel.
