Fuel property improvement and exhaust emission reduction, including noise emissions, using an oxygenated additive to waste plastic oil in a diesel engine

Abstract

This work reports on an extensive investigation of the physicochemical properties, engine performance, exhaust emissions, and fundamental energy and exergy parameters of waste‐plastic oils blended with an additive, diethyl ether and diesel. A four‐stroke single‐cylinder diesel engine was used for the engine experiments. The seven fuels in this study include a neat diesel, a neat waste plastic oil, two binary blends of diesel‐waste plastic oil, and three ternary blends of diesel with waste plastic oil and diethyl ether. The justification for selecting diethyl ether was to augment fuel properties in the blend and to further reduce emissions. The reasons for choosing waste plastic are not only to harness energy from waste plastic but also to offer an effective solution to the plastic waste management issue. The choice of diesel was to use it as a reference fuel for comparison with other fuels. Fuel properties were observed to be similar, and in some cases better, with the blends. Notable reductions in emissions with identical engine performance and energy and exergy parameters were observed with the five oxygenated blends (plastic oil blends) than with a reference diesel fuel. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

Experimental and optimization study on the effects of diethyl ether addition to waste plastic oil on diesel engine characteristics

“…13 However, when researchers investigated the use of diesel-diethyl ether blends or diethyl ether (DEE) as a supplemental fuel, they found that while PM emissions decreased due to reduced carbon content in the fuel, NO x emissions increased due to the higher oxygen content leading to elevated combustion temperatures. 6,19,20,23,24 Based on the ndings reported in previous publications, blending WPO with butanol and DEE resulted in a decrease in BTE and an increase in brake specic fuel consumption (BSFC) primarily due to the lower heating value of butanol and DEE. 4,6 However, the addition of biodiesel to the blended fuel led to an increase in BTE and a decrease in BSFC, likely attributed to the higher heating value and favorable combustion characteristics of the fuel.…”

“…One of its notable properties is an exceptionally high cetane number, which indicates its effectiveness in promoting air-fuel mixing within the combustion chamber, surpassing that of diesel fuel. 6,19,20,23,24 Thailand's agricultural sector is characterized by extensive cultivation of crops, with a primary focus on those rich in starch content. This abundance of starch-based crops presents an opportunity for ethanol production.…”

Utilization of Nanotechnology and Nanomaterials in Biodiesel Production and Property Enhancement

“…Due to their tiny size, particular characteristics, and traits, including a high surface area to volume ratio, considerable crystallinity, catalytic activity, adsorption capacity, and stability, nanoparticles (NPs) have several benefits over biodiesel production [2]. With additional features that support high potential recovery, carbon nanotubes, and metal oxide nanoparticles are often utilized as nanocatalysts to manufacture biofuel and biodiesel [3,4]. The use of nanotechnology in the manufacture and improvement of biodiesel is critically examined in this paper, along with the main obstacles and promising future developments.…”

Influence of hydrogenated diesel/H2O2 blend fuel on diesel engine performance and exhaust emission characterization

“…Reducing particulate matter (PM) and particularly in the Euro VI standards simultaneously is problematic owing to a converse relationship between and PM 18 . Numerous researchers are dedicated to developing new or improved after-treatment technology to reduce PM and non-methane volatile organic compounds (NMVOC) emissions 19 – 22 . Selective Catalytic Reduction (SCR) is the most sophisticated active emissions control technology utilized effectively in diesel engine vehicles 23 , 24 .…”
