The effects of nanoparticles as a biodiesel ingredient on the performance of a VCR diesel engine

The combustion, efficiency, and emission properties of a single-cylinder variable compression ratio diesel engine are examined in this research (B100A30C30). To create a homogeneous solution, the ultrasonicator is used in conjunction with a 30 part per million (ppm) concentration of Silicon Carbide (SiC) and Carbon Nanotubes(CNT),two common nanoparticles found in fuel combinations. The increased mixing and chemical reactivity offered by nanoparticles' greater surface area to volume ratio during combustion has improved the combustion, performance, and emission characteristics of diesel engines. The engine with nanoparticles (B20A30C30) has a thermal efficiency of braking that is 20 % higher than the engine with regular particles (B100). Following that, nitrogen oxide emissions reduced by 38%, carbon monoxide emissions by 68%, hydrocarbon emissions by 52%, and smoke emissions by 48%.
