Performance and Emission Characteristics of Diesel Engine Using Alumina Nanoparticle Blended Biodiesel Emulsion Fuel

Abstract

Diesel engines are widely used for their low fuel consumption and better efficiency. An investigation was carried out with a single cylinder diesel engine to establish the effects of alumina nanoparticle incorporation into the Canola biodiesel (BD) emulsion fuel. The Canola BD was formed from the Canola oil by transesterification process, and later the Canola BD emulsion fuel was prepared in the fraction of 83% of Canola BD, 15% of water, and 2% of surfactants (by volume). The alumina nanoparticles were blended with the Canola BD emulsion fuel at different ratios systematically. The entire study was conducted in the diesel engine using the three fuels, namely, neat BD, Canola BD emulsion fuel, and alumina nanoparticle blended Canola emulsion fuels consecutively. The experimental results revealed a considerable improvement in the brake thermal efficiency (BTE) for the alumina blended Canola emulsion fuels compared with that of neat Canola BD and Canola BD emulsion fuel. At the full load, the BTE observed for the Canola BD fuel was 30.7%, whereas it was 27.81% and 31.6% for the Canola BD emulsion fuel and alumina nanoparticle blended emulsion fuel, respectively. The use of a nanoparticle blended BD fuel reduced the hydrocarbon (HC) and carbon monoxide (CO) emissions but increased oxides of nitrogen (NOx) emissions due to the increased oxygen content in the BD fuel but it was reduced in nanoparticle blended fuel. The smoke emission was reduced by 50% with the use of the nanoparticle blended emulsion fuel.

EFFECT OF EGR & NANOPARTICLES ON PERFORMANCE AND EMISSION CHARACTERISTICS OF A DIESEL ENGINE FUELLED WITH PALM BIODIESEL AND DIESEL BLENDS

“…Adding 10, 20 and 30 ppm of CeO 2 nanoparticles to BD20 resulted in 0.2%, 0.3% 0.4% increases in BTE, respectively, at all loads when compared to neat BD20. The CeO 2 nanoparticles cause the complete combustion as it acts as the oxygen donor (Pandian et al, 2017;Anbarasu and Karthikeyan, 2015). Comparative fall in BTE was observed for tested fuels at various fractions of EGR (10% and 20% flow rate).…”

“…Many investigations were attempted to decrease the NO X emissions from biodiesel and diesel blends fuelled diesel engine. Anbarasu and Karthikeyan (2015) performed an experimental study on biodiesel and diesel with the addition of aluminium oxide nanoparticle in direct injection constant speed diesel engine. Aluminium oxide nanoparticle at 250 ppm and 500 ppm is added to methyl esters to view the effects on performance and emission characteristics.…”

“…The major drawback of using neat biodiesel in CI engines is its superior NO x emissions and lower thermal efficiency (Pandian et al 2018). NO x emissions should be controlled by suitable methods to meet the emission standards (Anbarasu et al 2015). Among many techniques, an emulsion process is preferred for the instantaneous decrease in PM and NO x emissions for a biodiesel-fueled diesel engine (Ravikumar and Saravanan 2016).…”

Performance and Emission Analysis of Diesel Engine Using Thermal Barrier Coating and Addition of Cerium Oxide Nanoparticles to Palm Biodiesel

“…Variations of unburned hydrocarbon emission are shown in Figure 9. It shows TBC engine emission level as very low when it is run by neat palm biodiesel and cerium oxide nanoparticles mixed palm biodiesel used conditions compared with base engine (Anbarasu et al, 2015). Unburned hydrocarbon emissions were reduced compared with a base engine on an average of 14, 21.4 and 26 ppm in neat palm biodiesel, 30 ppm and 60 ppm cerium oxide mixed palm biodiesel used TBC engine respectively (Anbarasu and Karthikeyan, 2016).…”
