Abstract
The review reports the results of various researches work on the engine performance and emission characteristics of diesel engine using different nanoadditives in jojoba biodiesel - diesel blends. Blending of diesel with biodiesel in a diesel engine has gained importance, due to its economical and environmental benefits. Jojoba biodiesel gained an importance as an alternative fuel over conventional diesel fuel even with their unfavorable effects of power reduction. The wide spread usage of nanoadditives to improve the combustion quality may be a good solution of this problem. Blending of nanoparticles as an additives in biodiesel – diesel blends improves the thermophysical properties, such as thermal conductivity, mass diffusivity and high surface area-to-volume ratio. Based on the results available in the literature, it has been found that nanoadditives with jojoba biodiesel - diesel blends improve the performance of diesel engine and reduced the emission of toxic gases depending upon the dosage of the nanoadditives.
Highlights
Nowadays, concerns have been raised about the limited resources of fuel oil and the environmental issues which directly linked to the combustion of these fuels [1]
In 2014, Attia and his coworkers carried out an experiment to study the effect of Al2O3 nanoparticles as nanoadditives in jojoba biodiesel - diesel blends on single cylinder diesel engine and they found a slight improvement in engine performance and lower CO and HC emission in comparison to blend without Al2O3 nanoadditive [15]
In 2018 they again conducted their experiment using different nanoadditive made of titanium oxide (TiO2) mixed with jojoba biodiesel – diesel – n-hexane blend (J30D5H) and study their effect on diesel engine performance and exhaust gas emission [20]
Summary
Concerns have been raised about the limited resources of fuel oil and the environmental issues which directly linked to the combustion of these fuels [1]. These modifications can help the researchers to achieve the specific fuel properties and to improve the engine performance.
