“…As shown previously, the high volatility, long main injection ignition delay, high oxygen content and low aromatic content of M30 reduced PM emissions significantly compared with M0. Soot emissions in diesel engines result from the balance between soot formation and oxidation [25]. Oxygen blends is key factor in reducing PM emissions.…”

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.

“…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%.…”

“…The 2,5-DMF/diesel blend also exhibited the lowest soot emissions, which further leads to increased combustion and thermal efficiencies. Furthermore, Wei et al [190] investigated the combustion and emission performance of diesel blends with 0-30% 2,5-DMF in a four-cylinder diesel engine. With respect to PM emissions, the number of accumulation mode particles was observed to decline when 2,5-DMF was added to diesel, but the number of nucleation mode particles, more harmful to humans and the environment, increased, which further leads to lower geometric mean diameter of particles.…”

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.

“…However, having the excellent start of fuel injection, the combustion takes place in a smaller volume, closer to the upper point of the piston. This fact increases the combustion temperature and pressure, resulting in higher nitrogen oxide (NO x ) content forming in the cylinder, reduced opacity, and hydrocarbon (HC) emissions [32][33][34][35].The comparison of brake-specific fuel consumption (BSFC) and engine efficiency η e of engines allows for the most objective assessment of energy indicators of the internal combustion engine [31,36,37]. These indicators enable comparing engines of different structures during their running on fuels of various composition.The main harmful components of exhaust gases of engines are products of incomplete combustion (carbon monoxide (CO), incompletely burnt HC, smoke) and NO x [31,38,39].…”

The investigation for new innovative solutions to reduce transport pollution is a priority for the European Union (EU). This study includes energy and a sustainable environment, as well as transport, logistics, and information and communication technologies. Energy ecological parameters of internal combustion depend on many factors: fuel, the fuel injection time, engine torque, etc. The engine’s energy ecological parameters were studied by changing engine torques, using different fuels, and changing the start of the fuel injection time. The selection of the optimum parameters is a complex problem. Multicriteria decision-making methods (MCDM) present powerful and flexible techniques for the solution of many sustainability problems. The article presents a new way of tackling transport pollution. The analysis of the energy ecological parameters of the experimental internal combustion engine is performed using the neutrosophic multi-objective optimization by a ratio analysis plus the full multiplicative form (MULTIMOORA) and step-wise weight assessment ratio analysis (SWARA) methods. The application of MCDM methods provides us with the opportunity to establish the best alternatives which reflect the best energy ecological parameters of the internal combustion engine.
