“…The possibility of using 2,5-DMF as a diesel fuel additive has also been investigated [181][182][183][184][185][186][187][188][189][190]. Chen et al [181] studied the performance of 2,5-DMF blends with diesel in a a multi-cylinder CI engine at a volumetric percentage of 30%.…”

“…Adding 2,5-DMF to diesel was observed to generally reduce PM concentration. Moreover, the use of 2,5-DMF/diesel blends was observed to slightly increase the NO x emissions, brake thermal efficiency and brake specific fuel consumption compared with using pure diesel fuel [188]. The combustion and emissions of three oxygenated ring HCs considered as diesel additives, including 2,5-DMF, were studied in a single-cylinder diesel engine by Zheng et al [189].…”

Abstract:There is growing interest in the use of furans, a class of alternative fuels derived from biomass, as transportation fuels. This paper reviews recent progress in the characterization of its combustion properties. It reviews their production processes, theoretical kinetic explorations and fundamental combustion properties. The theoretical efforts are focused on the mechanistic pathways for furan decomposition and oxidation, as well as the development of detailed chemical kinetic models. The experiments reviewed are mostly concerned with the temporal evolutions of homogeneous reactors and the propagation of laminar flames. The main thrust in homogeneous reactors is to determine global chemical time scales such as ignition delay times. Some studies have adopted a comparative approach to bring out reactivity differences. Chemical kinetic models with varying degrees of predictive success have been established. Experiments have revealed the relative behavior of their combustion. The growing body of literature in this area of combustion chemistry of alternative fuels shows a great potential for these fuels in terms of sustainable production and engine performance. However, these studies raise further questions regarding the chemical interactions of furans with other hydrocarbons. There are also open questions about the toxicity of the byproducts of combustion.

“…As aforementioned design scheme, PACA can be connected either to the secondary air holes or to the dilution air holes. Actuator position is considered as an important factor affecting combustor performance with plasma assistance [14]. The PAC tests with different actuator positions were carried out and compared to normal combustion results.…”

A plasma-assisted combustion test platform for annular combustor was developed to validate the feasibility of using plasma-assisted combustion actuation to reduce emission levels. Combustor outlet temperature and emission levels of O 2 , CO 2 , H 2 , CO, and NO x were measured by using a thermocouple and a Testo 350-Pro Flue Gas Analyzer, respectively. Combustor combustion efficiency was also calculated. The effects of duty ratio, feedstock air-flow rate, and actuator position on combustion efficiency and emission performance have been analyzed. The results show that the target of CO and NO x emissions reduction in plasma-assisted combustion could not be fully achieved for kerosene/air mixture with different combustor excessive air coefficients. It is also shown that plasma-assisted combustion with dilution air hole actuation is superior to that of secondary air hole actuation for the combustion of liquid-kerosene fuel. Besides, plasma-assisted combustion effect is more obvious with an increase of duty ratio or feedstock air--flow rate. These results are valuable for the future optimization of kerosene-fueled aero-engine when using plasma-assisted combustion devices to improve emission performance of annular combustor.unique capacity in producing reactive species and heat and modifying transport processes [2]. In the last two decades, great progress has been made in exploring the mechanisms of plasma chemistry interactions and energy distribution method in the discharge process.Non-equilibrium plasma is a type of plasma in which the electronic, vibrational, and rotational temperatures are very different and the electrons have significantly higher plasma temperature than the other gas components. Typical non-equilibrium plasma includes dielectric barrier discharge, gliding arc discharge, glow discharge, microwave discharge, streamer discharge, and corona discharge. Compared to equilibrium plasma, non-equilibrium plasma is more kinetically active, because it can rapidly produce active radicals and excite species through various plasma chemistry reactions, such as electron impact dissociation, excitation, and subsequent energy relaxation [1][2][3][4]. Productions of new species accelerate chain branching reactions and broaden the ignition kernel, while the elevated temperatures from the plasma reduce radical quenching caused by recombination and diffusion to the walls.Many impressive demonstrations of the advantages of plasma-assisted combustion (PAC) using non-equilibrium plasma discharge in emission control have been made. Dielectric barrier discharge, pulsed corona discharge, gliding arc discharge, and microwave discharge were used as plasma-assisted combustion actuation (PACA) method. These studies have shown that PAC has the prominent capacity to reduce NO x emission. Recently, by using PAC technology, SO x [5] and unburned hydrocarbons [5,6] in flue gas as well as soot formation in the exhausted gas of Diesel engines [7-9] have been successfully removed, which further demonstrate the strong capability of plas...

“…The authors recently investigated the emission and combustion of diesel-MF blends and diesel-DMF blends in a direct injection compression ignition (DICI) engine, and found that MF addition retarded the combustion phase of blended fuels and increased the brake thermal efficiency of diesel engine [14]. Diesel-MF or diesel-DMF [15] blending promoted NOx emissions but decreased soot emissions significantly. As for the unregulated emissions, diesel-DMF blending increased the acetaldehyde emissions, while the benzene and 1.3-butadiene emissions were reduced compared with pure diesel [16].…”

A direct injection compression ignition engine fueled by diesel blended with 10% or 30% mass proportion of 2-methylfuran was experimentally studied. The in-cylinder combustion pressure, regulated emissions and particulate matter emissions at different pilot injection timings and masses were investigated under the exhaust gas re-circulation mode. It was found the blending with methylfuran increased the peak in-cylinder pressure and retarded the combustion phase at different pilot injection timings. The addition of 30% methylfuran increased the peak in-cylinder pressure and heat release rate gradually along with the advancement of pilot injection timing. The NOx, HC, and CO emissions increased with the advancement of pilot injection timing when the pilot injection proportion was fixed at 20%, and the blending with methylfuran reduced HC and CO emissions but increased NOx emissions considerably. The 30% methylfuran addition could significantly reduce nucleation mode and accumulation mode particles at different pilot injection timings and masses compared with pure diesel. In addition, the particulate mass concentration of 30% methylfuranaddition remained at very low levels under all experimental conditions.
