“…However, a further rise in triacetin's dosage facilitates the CO formation due to the slower oxidation rate pertaining to higher viscosity content. A similar trend for CO emission was obtained by Tang et al, 36 Taghavifar et al, 37 Simsek et al 38 in the studies conducted on oxygenated fuel additives in S.I engine. Moreover, the impact of engine load on CO emissions was also analyzed by keeping constant the dosage of triacetin and methanol in the fuel blend.…”

Biodiesel, as an alternative fuel, has gained wide interest in recent years. However, despite the countless benefits, the enormous generation of glycerol-waste and higher production costs have been causing severe challenges to both the environment and the biodiesel economy’s survival. With the focus on maintaining its sustainability, the proper valorization of the crude glycerol is of vital importance. The objective of the present study is to harness and transform glycerol (a by-product of biodiesel) to triacetin and utilize it further as a fuel additive for spark ignition (SI) engine. Triacetin is a valuable compound of bio-based origin, having good anti-knock properties and higher oxygen content. Test fuels containing different blends of gasoline, methanol and triacetin were prepared and compared with neat gasoline. The Response Surface Methodology (RSM) based multi-objective technique was selected to optimize the engine output parameters like BTE, CO, CO2, HC and NOx emissions. The results indicate that the engine operating at 1.17 kW brake power and containing 90.73% gasoline, 4.94% methanol and 4.31% triacetin (by vol.) were found to be the optimum input parameter combinations which shows maximum BTE and lowest engine exhaust emissions as compared to other fuel blends. The estimated economic analysis of small-scale plants was also carried out, revealing that about 4.2% of revenue per kg of triacetin selling can be generated by running biodiesel and triacetin production analogously. Among various alternatives probed, the acetylation of glycerol to triacetin appears to be the ideal solution. It can serve the multiple purposes of reducing vehicular emission and improving the economic viability of burgeoning biodiesel industries and creating new opportunities, livelihoods, and jobs for humanity.

“…Moreover, the lowest NOX emissions were recorded at the highest ethanol level (E40) by 21%, which could be ascribed to the delayed ignition timing; this improvement did not decrease thermal efficiency, though. Taghavifar et al (2020) added 20% bioethanol into gasoline at an engine speed of 1400 rpm and different engine loads and measured NOX emissions under all conditions. Maximum NOX emission reduction was recorded by 60% at 75% engine load but offered no explanations for the observations made.…”

Ethanol can be used as an alternative fuel for spark-ignition (SI) engines to increase the octane number and oxygen content of ethanol/gasoline blends, thereby reducing dependence on fossil fuels and the exhaust emissions of incomplete combustion products. Although it is widely agreed that ethanol can reduce CO and HC exhaust emissions, the literature on ethanol and NOX emissions is far from conclusive; hence there is a need for an in-depth, updated review of ethanol/gasoline blends in SI engines and the relative production of NOX emissions. In light of that, the present work aims to provide a comprehensive literature review on the current state of ethanol combustion in SI engines to shed definitive light on the potential changes in NOX emissions under various operating conditions. The first part of this paper discusses the feasibility of ethanol as an alternative transportation fuel, including world production and ethanol production processes. The physicochemical properties of ethanol and gasoline are then compared to analyze their effects on combustion efficiency and exhaust emissions. Then, the pathways of NOX formation inside the cylinder of SI engines are discussed in depth. Finally, we review and critically discuss the effects of ethanol concentration in blends and different engine parameters on NOX formation.

“…In addition, a recent studies on the effect of a mixture of ethanol and isooctane on laminar burning characteristics [ 17 – 19 ], octane reaction on the methyl tert -butyl ether (MTBE) with gasoline [ 20 ]. Furthermore, application research on the effect of the use of ethanol and isooctane against flame speed [ 21 ], dynamic spray [ 22 ], macroscopic spray characteristics under flash boiling conditions [ 23 , 24 ], NOx emissions [ 25 , 26 ], particulate matter [ 27 ], and their impact on fuel efficiency have also been applied to the SI engine, and the results show that there is a significant performance improvement [ [28] , [29] , [30] ].…”
