Influence of Nanoparticles on Biodiesel Engine- A Review

Abstract

Biodiesel is an unrivaled alternative fuel that aims to increase the value of fossil fuels while also extending the life and cleanliness of diesel engines. Because of its closed carbon cycle, it decreases reliance on foreign fuels while also lowering greenhouse gas emissions. The numerous benefits of biodiesel are outweighed by a few disadvantages, such as increased nitrogen oxide emissions, incompatibility with cold weather conditions, and the need to repair engine equipment such as fuel filters, fuel tanks, and fuel lines on a frequent basis owing to clogging. By using nanoparticles as fuel additives, there is even more potential for improving fuel qualities and overcoming limitations.The thermophysical characteristics of the fuel mixes were improved, the heat transfer rate was increased, and the fuel mixtures were stabilized. In addition, depending on the dose of nanofluid additives, there was an improvement in engine performance metrics and a reduction in exhaust emissions.The current study highlights the most recent research on nanoparticles as a liquid fuel additive. The impact of dispersion of various nanoparticles on improving performance parameters and lowering emissions in a CI engine running on diesel-biodiesel blends is examined. The creation of an economically viable and practicable nanoparticle addition for diesel and biodiesel fuel is suggested as a future goal. However, a few of the constraints and problems identified in this analysis must be overcome before they can be completely implemented in commercial applications.
