In ternary blend fuelled diesel engines, nanoparticles are used as an additive in biofuel production and as a fuel additive: A review

The depletion of fossil fuels has led to a move towards renewable and cleaner diesel fuel in recent years. Researchers are studying different types of biofuels. Diesel fuel may soon be challenged by biodiesel. Due to lower calorific value, lower cetane number, and higher density, biodiesel cannot substitute for diesel fuel completely. Thus, diesel engines that use biofuel blends are preferred. This study examines the combustion characteristics, emissions, and performance characteristics of biodiesel-diesel blend-powered diesel engines. The study aims to provide a comprehensive assessment of biodiesel-diesel blends. The potential and application of nanoparticles in bioethanol production have been studied in a large number of research studies in the past. Various nanoparticle ratios of biofuels are collected and examined in this study to assess the effects of nanoparticles in diesel fuel. Various methods for improving engine performance are examined. From preparation of feedstock to chemical reactions, nanoparticles are useful in the development of biofuels. In compared to blends containing no alcohol or alcohol with or without nanoparticles, adding nanoparticles to biodiesel-diesel blends reduces brake-specific fuel consumption by 18 to 20 percent. Moreover, nanoparticles are highly thermally conductive, improving brake performance by 2% to 5% and improving combustion. The reviews found that NOx emissions increased by 50%, whereas HC, CO, and PM emissions decreased considerably. According to the findings, introducing nanoparticles to biodiesel and biodiesel blends as a fuel for CI engines could dramatically improve performance while reducing emissions.
