Spectroscopic verification of biodiesel synthesis from turpentine tree oil through two-step chemical reactions: investigation of the use of synthesized biodiesel and acetone as fuel additives in diesel engines, Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 46(1), 35-53, DOI: 10.1080/15567036.2023.2277363https://www.tandfonline.com/doi/full/10.1080/15567036.2023.2277363https://hdl.handle.net/11468/13048In this research, the influence of acetone addition in diesel engines was assessed, examining its implications on combustion, performance, and emissions. Biodiesel was synthesized from turpentine oil via a dual-step process involving esterification and transesterification, validated through Fourier Transform Infrared Spectroscopy. Nuclear Magnetic Resonance confirmed the presence of methyl esters while Gas Chromatography-Mass Spectrometry facilitated the biodiesel component analysis. Tests on mixed fuels, conducted under varied load settings at 1500 rpm, showcased that introducing acetone to diesel escalated in-cylinder pressures, heat release rates, and gas temperatures but mitigated pressure rise rates. In contrast, its incorporation in the diesel/biodiesel blend revealed a decline in the aforementioned parameters and an enhancement in pressure rise rates. Specifically, diesel with acetone yielded a 2.72% and 8.07% reduction in brake specific fuel consumption and carbon monoxide emissions, respectively. However, brake thermal efficiency marginally elevated by 0.01%, accompanied by a 4.19% surge in nitrogen oxide emissions. Incorporating acetone in the diesel/biodiesel blend led to a 1.13% reduction in brake thermal efficiency and a notable 7.53% cut in nitrogen oxide emissions, while brake specific fuel consumption and carbon monoxide emissions rose by 1.14% and 3.61%, respectively. These effects of acetone necessitate additional research to explore its potential as an additive.eninfo:eu-repo/semantics/embargoedAccessTerebinth oilEsterificationSpectroscopyAcetoneEmissionsCombustionArticle4613553WOS:0011045564000012-s2.0-8517724151810.1080/15567036.2023.2277363N/AN/A
