Abstract

This paper deals with the study on the influence of the effects of iron oxide nanoparticle additives when added to ternary fuel (diesel + mahua methyl ester + pentanol) on the emission, combustion, and performance characteristics of a four stroke, single cylinder, common rail direct injection diesel engine working at a constant speed and varying operating scenarios. Doping is done in various proportions to the nanoparticle additives with the help of a homogenizer and ultrasonicator where the cationic surfactant used is CTAB (cetyl trimethyl ammonium bromide). Iron oxide nanoparticles were used as additives in fuel in the dosages of 40 ppm, 80 ppm, and 120 ppm respectively and TF (ternary fuel) is obtained by mixing 10% pentanol, 20% mahua, and 70% diesel together is used for the experimental study. The experimental study revealed that while using the nanoparticle additives blended ternary fuel (i.e., TF80), the number of harmful pollutants like smoke (5.38%), HC (6.39%), carbon monoxide (10.24%), and NOx has reduced to a considerable extent and there was a commendable improvement in the BTE by 8.8%. So, we can summarize that when ternary fuel and nano additives are blended together the combustion and performance of the engine was improved considerably and pollutant emissions were decreased.

Highlights

Ternary fuel blends have become very popular recently around the world due to its ability to use as a substitute for conventional diesel. (Rakopous et al 2008) investigated the influence of alcohol with different concentrations (10% and 5%) along with diesel fuel
A sincere effort has been made to understand the major impacts of MME20 (80% diesel fuel + 20% Mahua methyl ester), Ternary fuel, Ternary fuel 40 (Ternary fuel mixed with iron oxide additives of 40 ppm), Ternary fuel 80 (Ternary fuel mixed with 80 ppm iron oxide additives) and Ternary fuel 120(Ternary fuel mixed with iron oxide additives of 120 ppm) blends on exhaust emissions, combustion and engine performance in a four stroke, single cylinder, common rail direct injection diesel engine and the obtained results are compared with that of conventional diesel conventional diesel (D100)
In order to obtain the baseline data conventional diesel was used in the engine, MME20 (80% diesel fuel + 20% Mahua methyl ester), Ternary fuel, Ternary fuel 40 (Ternary fuel mixed with iron oxide additives of 40 ppm), Ternary fuel 80 (Ternary fuel mixed with 80 ppm iron oxide additives) and Ternary fuel 120(Ternary fuel mixed with iron oxide additives of 120 ppm were used

Summary

Introduction

Ternary fuel blends have become very popular recently around the world due to its ability to use as a substitute for conventional diesel. (Rakopous et al 2008) investigated the influence of alcohol with different concentrations (10% and 5%) along with diesel fuel. (Soudagar et al 2018; Gugulothu et al.2019) investigated the impact of nanoparticles on performance characteristics of biodiesel blended diesel engine and reported that incorporation of nano additives resulted in an increase in improvement of thermophysical properties, decrease in emissions from engine tailpipe, better stabilization of air-fuel mixture. This value is obviously within the acceptable uncertainty range i.e., less than ± 5%
