As the scientific community brings to light the environmental and sustainability concerns linked to the exclusive use of diesel in transport, initiatives have been launched to identify a viable alternative fuel. This alternative aims to address the shortcomings of diesel. The growing realization of our finite fossil fuel reserves, coupled with an increased understanding of their negative environmental effects, has accelerated the search for substitute fuels. These alternatives are derived from renewable organic sources, ensuring sustainability and reduced emissions. This review thoroughly examines the effects of oxygenated and nanoparticles additives on diesel engine performance. The additives under review are divided into four main categories: metal-based, oxygenated, non-metal-based (including boron-based and carbon-based), and water additives. Carbon-based alcohols offer advantages over base fuels, providing additional energy content and helping control emissions through their cooling effect. Conversely, nanoparticles demonstrate remarkable additive capabilities due to their physical properties, offering increased surface area for enhanced fuel reactivity and improved base fuel atomization. The inclusion of metal-oxide nanoparticles has notably boosted the viscosity, cetane number, and heating value of biodiesel. Moreover, the higher oxygen atom content in biodiesel-nanoparticles blends has enhanced the combustion process quality. This review summarizes researchers' investigations into the addition of different alcohols to diesel and biodiesel in various diesel engines. Critical properties of each alcohol have been evaluated, and their impact on compression ignition engine performance, combustion, and emissions characteristics has been studied. The review concludes by summarizing findings from previous research efforts, highlighting potential challenges, and offering guidelines for future research on the impact of additives.
