A COMPREHENSIVE REVIEW ON THE EFFECT OF NANO-ADDITIVES IN DIESEL-BIODIESEL FUEL BLENDS

mechanical engineering

The paper discusses the potential of biodiesel as an alternative liquid fuel. Biodiesel offers benefits such as extended engine life, clean burning, and reduced greenhouse gas emissions due to the trees used for feedstock absorbing carbon. It also helps reduce dependence on fossil fuels and supports the economy. However, biodiesel faces challenges like high viscosity, poor cold flow properties, increased nitric oxide emissions, and low oxidation stability compared to conventional diesel. One promising solution is the addition of nanoparticles, which enhance the fuel's thermochemical properties. The paper explores studies on nano-sized particles in diesel-biodiesel fuel emulsions, focusing on their impact on engine performance, emissions, and longevity. It also delves into the effects of different nanoparticle sizes and concentrations on diesel engine behaviour. Additionally, the paper covers the preparation of nanofluid, various characterization methods, and techniques for enhancing the stability of biodiesel.
