Abstract

Using three different fuel sequences –biodiesel–diesel (B20), biodiesel–chemically and biologically synthesized nanoparticles(B20A30C30), and biodiesel–chemically and biologically synthesized nanoparticles (B20A30C30). This study investigates a single-cylinder variable compression ratio diesel engine's combustion, efficiency, and emission characteristics (B100A30C30). The ultrasonicator is employed in concert with 30 parts per million (ppm) concentration of titanium oxide (TiO2) and zinc oxide (ZnO), two typical nanoparticles found in fuel mixtures, to form a homogenous solution. As a result of the greater mixing and chemical reactivity offered by nanoparticles' higher surface area to volume ratio during combustion, diesel engines' combustion, performance, and emission characteristics have all been improved. The engine with nanoparticles (B20A30C30) has a 16% higher brake thermal efficiency than the engine with conventional particles (B100). Following that, nitrogen oxide emissions were reduced by 32%, carbon monoxide emissions were reduced by 62%, hydrocarbon emissions were reduced by 48%, and smoke emissions were reduced by 40%.
