DIESEL ENGINE TOXICITY REDUCTION THROUGH VEGETABLE OIL ENVIRONMENTAL ADDITIVES

Abstract

Modern engine construction is challenged by the imperative to mitigate emissions of harmful substances from internal combustion engine exhaust gases, necessitating an urgent focus on the reduction of toxic components released into the atmosphere [1, 2]. The toxicity of internal combustion engines is quantified by emissions of specific pollutants, subject to stringent contemporary regulations. Diesel engines (henceforth referred to as "diesels") are gauged by the normalized levels of toxic constituents, encompassing nitrogen oxides (NOx), carbon monoxide (CO), light unburned hydrocarbons (CHx), and solid carbon-based particles (soot). Emissions of sulfur oxides (SOx) are indirectly restricted through fuel sulfur content regulations capped at 8. The progressive intensification of toxicity-related mandates for diesel engines, as evidenced by figures 1 and 2 along with table 1, underscores the exigency to adopt novel engine technologies and approaches to curbing diesel engine toxicity. In this context, this study underscores the imperative to incorporate strategies that mitigate diesel engine toxicity, delineating potential avenues within the realm of engine design enhancement, operational considerations, and exploration of alternative fuel options [4]. The profound environmental benefits offered by biofuels, specifically those possessing favorable ecological attributes, have garnered substantial attention [5-7]. This research undertakes the objective of evaluating the efficacy of integrating vegetable oils as environmentally beneficial additives within diesel fuels, further probing their ramifications on the technical and economic facets of the machinery.

The conducted research comprises a multifaceted analysis, evaluating the viability of vegetable oil-based additives in diminishing the ecological impact of diesel engines. Through comprehensive empirical investigation, this study not only quantifies the abatement of toxic emissions achieved via these additives but also scrutinizes their influence on the overall operational and financial efficacy of the machine unit. The results of this study hold pivotal implications for both the domain of engine design and environmental conservation, providing pragmatic insights into a sustainable pathway for reducing the toxicity of diesel engine emissions.
