Fossil fuels have posed a great danger to the existence of living things in the world, and pollution is wreaking havoc on the planet’s ecosystems. Global fuel consumption has risen precipitously because of urbanization, industrialization, and an ever-increasing human population. It has become necessary to consider alternatives to petroleum-based fuels such as diesel and gasoline considering our current overdependence on these traditional sources of energy. In this scenario, biodiesel presents an excellent opportunity. Biodiesel is highly replicable since it is made mostly from renewable resources, such as food and non-edible plants. Biodiesel cannot be used directly in engines because of its high viscosity. The relevant literature is categorized in this study. This research also tries to highlight the benefits of utilizing biodiesel and the advances made by researchers. Various articles about biodiesel fuel and its blends in diesel and engines were gathered and sorted depending on the blending techniques used (complete substitution without diesel or partial substitution). The use of biodiesel in engines and its ability to compete with fossil fuel diesel in performance were among the topics covered in this research.
Biodiesel’s effect on engine performance and environmental impact will be examined in this article. The study reveals that B20 biodiesel will be a replacement for fossil fuel diesel as an alternate fuel. The results reveal that the brake specific fuel consumption (BSFC) and brake thermal efficiency (BTE) for B20 biodiesel are identical to diesel and hence can serve as a potential alternative to petroleum-based fuels.
