In this research, the influence of acetone addition in diesel engines wasassessed, examining its implications on combustion, performance, and emissions.Biodiesel was synthesized from turpentine oil via a dual-step processinvolving esterification and transesterification, validated through FourierTransform Infrared Spectroscopy. Nuclear Magnetic Resonance confirmedthe presence of methyl esters while Gas Chromatography-MassSpectrometry facilitated the biodiesel component analysis. Tests on mixedfuels, conducted under varied load settings at 1500 rpm, showcased thatintroducing acetone to diesel escalated in-cylinder pressures, heat releaserates, and gas temperatures but mitigated pressure rise rates. In contrast, itsincorporation in the diesel/biodiesel blend revealed a decline in the aforementionedparameters and an enhancement in pressure rise rates.Specifically, diesel with acetone yielded a 2.72% and 8.07% reduction inbrake 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. Incorporatingacetone in the diesel/biodiesel blend led to a 1.13% reduction in brakethermal efficiency and a notable 7.53% cut in nitrogen oxide emissions,while brake specific fuel consumption and carbon monoxide emissionsrose by 1.14% and 3.61%, respectively. These effects of acetone necessitateadditional research to explore its potential as an additive.
