Emissions Analysis on Diesel Engine Fueled With Palm Oil Biodiesel and Pentanol Blends

Abstract

EMISSIONS ANALYSIS ON DIESEL ENGINE FUELED WITH PALM OIL BIODIESEL AND PENTANOL BLENDS ITRODUCTIONEscalating environmental issues coupled with depletion in petroleum resources have paved the way for global efforts to search for eco-friendly fuels (Amirnordin et al., 2013). Automobiles are widely acknowledged as the major source of greenhouse gas emissions. Diesel engines play a significant role in the power and automobile sectors of industry largely because of its durability and economy. However, diesel engines emit higher emissions when fueled with diesel.A lower emission alternative is needed to lessen the demerits of fossil fuel (Harmiwati and Rahmad, 2015). Biodiesel is made up of long chain alkyl esters produced by reacting lipids with alcohols (Lam et al., 2011). Biodiesel can be deployed in diesel engines without any modification. It can also be blended with petroleum diesel. In spite of its many advantages, the major drawbacks of biodiesel concern higher NO X emissions, viscosity and density and lower calorific value (Jaat et al., 2014). Many studies have proven that by appending higher alcohols to biodiesel much of the drawbacks are reduced (Karabektas et al., 2009; Murcak et al., 2013;Wang et al., 2015). Higher alcohols such as butanol, hexanol and pentanol are incorporated in biodiesel as an oxygenated additive (Rakopoulos et al., 2010). Blending, fumigation, emulsion and dual fuel injection are the existing techniques to append alcohols to fuel. Alcohols can be blended to liquid fuel in the range of 10%-30% by volume.

Investigation on the Emission Reduction Technique in Acetone-Biodiesel Aspirated Diesel Engine

“…But very few works have been carried out on neat alcohol-biodiesel (Venkata Ramanan and Yuvarajan, 2015a, b;Devarajan et al, 2017;. Dual-fuel blending is an effective technique for reducing the emissions from diesel engines (Radhakrishnan et al, 2017;Santhosham and Aghalayam., 2016;Devarajan et al, 2017a, b). Hence in this work, the author makes the effort to reduce the emissions of neat biodiesel fueled engine by adding acetone to biodiesel as an emulsion.…”

Utilization of Pentanol as Biofuels in Compression Ignition Engines

“…However, Sridhar et al (2018) reported that 1-pentanol/WCO biodiesel blends decreased the emissions of NOx, HC, and CO simultaneously compared to neat biodiesel, with a slight penalty of BTE. It was also observed by Radhakrishnan et al (2017) that for palm oil biodiesel/pentanol blends (B90P10 and B80P20), CO, HC, NOx, and smoke emissions were reduced compared to neat palm oil biodiesel.…”

Fluid Characteristics of Biodiesel Produced from Palm Oil with Various Initial Water Contents

“…Biodiesel, which is composed of longer fatty acids or more saturated fatty acids, appears to have greater kinematic viscosity [30]. Hence, biodiesel made from palm oil has greater kinematic viscosity than those biodiesels made from corn oil, canola oil, rapeseed oil, and soybean oil [26,31], primarily due to the higher content of saturated fatty acids of the PME in those biodiesels. Biodiesel consisting of less unsaturated fatty acids content was produced from palm oil with water content either relatively higher or lower than 0.05 wt.…”
