“…The engine performance of 2,5-DMF has been extensively investigated [12,[172][173][174][175][176]. Zhong et al [12] tested the performance of 2,5-DMF, compared with that of ethanol and gasoline in a single-cylinder gasoline direct-injection (GDI) research engine at mean effective pressures of 3.5-8.5 bar.…”

“…Most importantly, 2,5-DMF was shown to exhibit the lowest carbonyl and formaldehyde emissions compared with gasoline, ethanol, methanol and n-butanol. Moreover, Daniel et al [174] further examined the combustion performance and emissions levels of 2,5-DMF at the optimum spark timing of 10 crank angle degrees retard in a DISI engine. The spark sensitivity of 2,5-DMF at a full load was below gasoline and butanol, but greater than ethanol and methanol.…”

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.

“…They found that an increase in injection pressure results in higher droplet collision rate, higher inertia collisions and increase of axial droplet mean diameter. Daniel et al (Daniel, Tian et al 2012) compared the sensitivity of different fuels to ignition timing. They showed that DMF had good performance in cold start.…”

In the present study the fuel spray of a gasoline direct injected engine with multi-hole injector is simulated. Simulation inputs data, injection flow rate and spray cone angle are obtained from previous experimental studies. Log-normal distribution with different standard deviation is used for initial droplet size as the primary break-up model in order to reach the agreement between experimental and calculated spray tip penetration.As the first step, only one plume of spray injected into a quiescent air environment is simulated and validated by varying break-up model and standard deviation. Then, with coefficient obtained from the single jet simulation all six spray jets are simulated based on the injector nozzles geometry. The comparison between single-jet simulation and multi-jet simulation shows that validated model coefficients for the single-jet spray cannot be used for multi-jet spray simulation without significant modifications due to adjacent jet interaction and pressure drag. A set of new coefficients for the multi-jet spray is presented

The rapid development in methods for transforming non-edible biomass into platform chemicals and fuels has accelerated over recent years. However, the determination of whether these 'next-generation' biofuels perform in a satisfactory manner in engines, turbines and burners has lagged behind. The evaluation of the ecological and toxicological aspects has also been unable to keep up. We show, by using 2,5-dimethylfuran (DMF) as a concrete example, how a range of studies is needed to establish the benefits and risks of using a particular biofuel. In this regard, the variable with the largest impact about which little is known is probably the behaviour of DMF when it is accidentally introduced into groundwater. A primary consideration is to avoid a repetition of the methyl tert-butyl ether (MTBE) fiasco.
