Effect of adding nanomaterial using Ruta oil methyl esters on engine performance and combustion emissions

Abstract

The focus on alternative fuels has increased greatly because of the diminishing availability of petroleum resources and the rising worries about the environment. Biodiesel, a sustainable fuel source, has the capacity to serve as a feasible alternative to traditional fossil fuels. The latest progress in nanotechnology has enabled the development of fuel additives made of nanoparticles that can be used in internal combustion engines. Studies conducted in the past have demonstrated that these additives have the ability to improve the performance of the engine. In this innovative research, we explored the impact of adding aluminum oxide nanoparticles (Al2O3) to a fuel mixture consisting of 20% Ruta biodiesel and 80% diesel, aiming to evaluate enhancements in performance and decreased emissions. In our experiments, we utilized a diesel engine with a single cylinder and four strokes, running steadily at 1500 revolutions per minute. The RB20 mixture underwent exposure to a 35 ppm concentration of Al2O3 nanoparticles through the utilization of an Ultrasonicator. The findings show that the brake-specific fuel consumption (BSFC) was enhanced when using the DF80+RB20 mixture. In comparison to regular diesel fuel, the brake thermal efficiency (BTE) saw an increase when using a blend of 80% diesel fuel and 20% rapeseed biodiesel. The emissions, a key element affected by the type of fuel used, were reduced for all mixed fuels in comparison to pure diesel fuel (DF). The presence of nanoparticles also played a role in lowering the rate at which combustion pressure increased, leading to a decrease in combustion. These findings suggest that the DF8 0+R B2 0 blend is suitable for diesel engines without the need for alterations.
