Biodiesel has been considered as an alternative to diesel and leads to meet the future energy demand. Biodiesels, especially second-generation biofuel from non-edible oil are substitute for diesel in CI engine due to its environmental benefits. The use of cotton seed biodiesel has shown benefits such as low-level exhaust emissions, easy availability and can be used for CI engines without any modification. Since the blending of biodiesel and diesel are suggested to be used in diesel engine with low blending ratios, fuel additives are considered as suitable option for utilization of biodiesel at higher blending ratios. Addition of additives in blends accelerates fuel instability reactions during combustion and improves the performance of the engine. The experimental investigation was conducted at different engine loads in a single cylinder diesel engine using diesel with 20 percentage of cotton seed biodiesel blended fuel (B20). Along with this fuel multi-walled carbon nanotubes (MWCNTs) were mixed as additives in mass fraction of 100 ppm (B20C100) and 150 ppm (B20C150) by using ultrasonicator. The results revealed that there is substantial enhancement in brake thermal efficiency 4.9% and 5.92% for B20C100 and B20C150 at lower loads due to addition of MWCNTs. The results also showed that there is marginal reduction of harmful emissions such as hydrocarbons, carbon monoxide and smoke for the nano-additive blended biodiesel.
