“…In this context, furan derivatives (see Fig. 1), produced from non-edible feedstocks, especially 2-methylfuran (MF) and 2,5-dimethylfuran (DMF), were demonstrated to have additional benefits as next generation alternative fuels due to their significant advantages over traditional biofuels [3][4][5][6][7]. For instance, DMF-diesel blends produce less soot compared to blends of diesel and n-butanol [3,5].…”

“…The D p varies from 8 to 19 nm and 7 to 35 nm for diesel-alcohol blends and diesel, respectively, at full load. 384 The primary particle sizes were <40 nm and exhibited a linear relationship with the engine load, as shown in Figure 29. 289 Oxygenated fuels increased the NMPs ( D p <20 nm) because oxygenated fuels diminished the soot surface growth and coagulation, 394 resulting in smaller D p .…”

Particulates from compression ignition (CI) engines have received serious attention in the last two decades. CI engines emit higher particulate matter (PM) and nitrogen oxides (NOx) than spark ignition (SI) engines. Both these species are harmful to human health and the environment. Compared to NOx emissions, PM constitutes many more chemical species in solid and liquid phases. This review paper focuses on soot morphology and chemical characterization of PM emissions from CI engines. Effects of different fuels, lubricating oil, and engine operating conditions on particulate characteristics are analyzed exhaustively. The first part of this paper focuses on the effects of particulates on living organisms, the consequences of exposure to diesel particulates, and the composition of diesel particulates. In recent decades, micro and nano-scale characteristics of PM have been exhaustively investigated to understand its structure, formation, and chemical functionalities. Typically, particulates comprise of elemental carbon (EC), organic carbon (OC), polycyclic aromatic hydrocarbons (PAHs), the soluble organic fraction (SOF), and trace metals. This paper summarizes most aspects of diesel particulate emissions for the benefit of active researchers in the field and underlines the importance of particulate emission reduction from the CI engines. Diesel combustion generates particles with enormous long-chain aggregates of smaller sizes and immature soot particles. Low-temperature combustion (LTC) modes and oxygenated fuels reduce the soot emissions and generate compact/clustered aggregates. Oxygenated fuels in CI engines produce more nucleation mode particles (NMPs) and high-reactivity soot aggregates. Higher trace metal concentrations were observed in diesel origin particulates than biofuel origin particulates. Biodiesel origin particulates possess higher mutagenicity and carcinogenicity because of nitro-PAHs. Transient engine operations cause higher particulates than steady-state engine operations.

“…Xiao et al 95 used a DICI engine fueled with blends of diesel fuel with 2-MF (mass fractions of 2-MF of 10%, 20%, and 30%). The engine speed was about 1800 rpm and the load was varied from 0.13 to 1.13 MPa BMEP.…”

“…Studies on the use of the diesel/furan derivative blends in engines, − as well as in premixed ethylene–air flames at atmospheric pressure, have shown that soot emissions are significantly reduced compared to pure fuel. Moreover, if a correct EGR rate is used, the soot and NO x emissions can be addressed simultaneously .…”

2,5-Dimethylfuran (2,5-DMF) and 2-methylfuran (2-MF) are furan derivatives that are shown to be able to reduce soot emissions from diesel engines. However, their capacity to form soot is high due to their cyclic structures. Therefore, the question arises that if the tendency to form soot of these oxygenated compounds is high, how do they have the ability to reduce soot emissions when added to diesel fuel. The operating conditions, as well as their physicochemical and combustion characteristics, can contribute significantly in such reduction. Moreover, the reactivity and physicochemical properties of the soot originated in the combustion chamber can also be important. However, this factor is hardly taking into account when an explanation is given for the reduction of soot emissions when furan derivatives are used. With the aim of analyzing the main factors that control the reduction of soot emissions from diesel engines when diesel/furan derivatives blends are used, the present review paper compiles and analyzes the studies that address: (1) the reduction of soot emissions when diesel/2,5-DMF and diesel/2-MF blends are used in diesel engines; (2) the formation of soot precursors and soot from the conversion of 2,5-DMF and 2-MF at laboratory-scale; and (3) the reactivity and characteristics of soot formed from the conversion of blends of a base fuel with 2,5-DMF or 2-MF and in the conversion of pure 2,5-DMF and 2-MF. This compilation will help focus future research works that may help understand the phenomena through which soot emissions are reduced when diesel fuel is blended with 2,5-DMF or 2-MF.
