“…The potential of the different fuels is evaluated in four operating points, whose main engine settings are shown in Table 3. The tests proposed are representative of the conditions found in the NEDC for a vehicle of an inertia weight class of 1590 kg [42]. As shown in Table 3, the CA50 and NOx emissions were kept constant for each operating point.…”

“…The SCE used for the tests has a compression ratio of 15:1 and has a state-of-theart series production fuel injection system. In addition, the engine conditions selected for the tests were based on realistic operating conditions, with three of the four tests within the NEDC range for an inertia weight class of 1590 kg [46]. The SCE specifications, engine operating conditions and injection details are summarized in Figure 14 (left) presents soot emissions measurements at the four engine operating conditions for all fuels.…”

Thus, fundamental spray characteristics related to fuel vaporization and fuel/air mixing process for 2-Methyltetrahydrofuran, Di-n-butyl ether and 1-octanol has been studied and compared with conventional EN590 Diesel fuel. For this purpose, OH* chemiluminescence and shadowgraphy measurements in a high pressure chamber as well as 1D simulations with a spray model have been carried out at different operating conditions representative of the NEDC driving cycle. Finally, measured soot emissions in the singlecylinder engine were presented and discussed.Results from the high pressure chamber presented very good agreement in terms of liquid length and vapor penetration with simulation results. Thus, some analytical expressions related to macroscopic spray characteristics have been proposed and validated experimentally for all four fuels. Finally, the single-cylinder engine results confirmed the relevant role of soot formation on final emissions for 1-octanol and 2-MTHF. In addition, DNBE showed greater soot oxidation potential than diesel and other TMFB candidates.

“…However, the oxygen content in the molecule and a different soot-oxidizing mechanism overcome the negative influence of the high ignitability and minimize the particulate matter emissions [8] examines the soot-oxidizing mechanism in the process of DBE combustion and reports missing soot luminescence in the post-oxidation combustion phase, probably resulting from a mechanism unusual for pure hydrocarbons and different particle composition. Additionally, [9] points out the very good mixture formation properties of DBE, which are a consequence of low viscosity (dynamic viscosity 0.64 mPa.s at 25 °C [3]), low boiling temperature and low heat of vaporization. These aspects result in high Reynolds numbers and a proper spray break-up [9,10].…”

As stated in [11], the spray structure of neat DBE and its blends with diesel fuel show a larger spray angle and shorter liquid penetration length than pure diesel, providing improvements to atomization behaviour.…”

Fuels from lignocellulosic biomass have the potential to contribute to sustainable future mobility targets by reducing the fossil CO 2 emissions of the transport sector. Of special interest for the diesel engine are oxygenated fuels, since they can help to solve traditional conflicts of objectives like the soot-NOx trade-off or the efficiency-NOx compromise. Dibutyl ether (DBE) and oxymethylene ethers (OME) are among the most promising fuel candidates. The suitability of these compounds for diesel engines is investigated in this study. The fuels are injected in pure form as well as a diesel-biofuel blend with 20% volumetric biogenic share. During the course of these investigations special attention is given to soot and particle emissions, and also to measured engine efficiency. The combustion tests are combined with an analysis of suitable production paths of the evaluated bio-ethers as second generation biofuels. Production simulation shows high greenhouse gas savings potential, but also high investment costs.
