Abstract

Nanoparticles are an emerging concept for increasing fuel properties. The purpose of this research work is to determine the effect of magnesium oxide nanoparticles on the performance and emission characteristics of diesel engines that run on a spirulina microalgae biodiesel blend (B20) as a fuel. The ultrasonication was used to disperse MgO nanoparticles in B20 fuel at various concentrations (25, 50, 75, and 100 ppm). The significant findings indicated that B20+100 blends reduced specific fuel consumption by 20.1% and had a 5.09% higher brake thermal efficiency than B20. B20+100 blends reduced CO, hydrocarbon, and smoke emissions by a maximum of 32.02%, 30.03%, and 26.07%, respectively, compared to B20.

Highlights

Fossil fuels are considered conventional and nonrenewable sources
The current study investigates the extraction of oil from spirulina microalgae and its transesterification to methyl ester
The BSFC is a ratio computed by dividing the amount of fuel spent by the amount of energy produced over a given period

Summary

Introduction

Fossil fuels are considered conventional and nonrenewable sources. There are various effective methods for lowering diesel engine emissions, including engine modification, combustion enhancement, and exhaust gas treatment systems. Engine combustion appears to be the most preferred method, as it requires only minimal changes to existing engine systems rather than new designs. This is performed by modifying the fuel injection system, using fuel additives, and adjusting the fuel characteristics. Recent advancements in nanotechnology have allowed nanotechnology to develop nanosized molecules, which aid in improving thermal properties, assisting combustion with its significant volume-surface ratio to improve fuel characteristics and performance while lowering diesel engine emissions [1].
