“…Particularly, the blend CEC (50 vol-%) and BtL (50 vol-%) features the potential to diminish both, PM and NO x , at high EGR. These results regarding admixtures containing BtL confirm previous surveys, e.g., Schaberg et al (2002) and Larsson and Denbratt (2007).…”

Diesel engines, in combination with modern turbocharging and common rail injection systems, feature comparably high efficiencies coupled with favorable torque characteristics. Therefore, besides the utilization in commercial vehicles, diesel engines gained large market shares within the passenger car sector. The European Union regulates the deployment of biofuels and has issued several targets throughout the years; focusing on the urge to reduce carbon dioxide emissions, as well as on the growing demand for independence of fossil energy sources. This contribution presents investigations on fuel blends containing different shares of biomass to liquid, hydrotreated vegetable oils, and fatty acid methyl ester applied in a state of the art light-duty diesel engine. In general, the reviewed fuel blends exhibit good applicability for the utilization in the test engine with default settings of injection timing and exhaust gas recirculation; adjustments on the just mentioned parameters unveil further potential in terms of emissions and efficiency. Particularly the potential of biomass to liquid blends to partly mitigate the tradeoff between particulate matter and nitrogen oxides deserves distinct attention.

“…This decrease ranges from about 1.2 to 0.3 g/cm 3 as particle size increases from 50 to 300 nm. Schaberg, Kittelson, Zarling, and Waytulonis (2002) measured the ratio of filter mass to SMPS volume for two different Diesel engines and found the effective density ranged from 0.74 to 0.87. These results are for Diesel engines, thus we have assumed an effective density of 1.0 for our calculations.…”

“…The particle sizes of interest are in the nano-metre (nm) range, and it is well established in the literature that particles can be separated into three size ranges, known as the nucleation mode, the accumulation mode, and the coarse mode [4,5,6,7]. The nucleation mode contains the smallest particles (3nm to 50nm [4,5]), and is formed mainly through the nucleation of material from the gas-phase during exhaust cooling, although it can also be solid material such as ash.…”

“…The nucleation mode contains the smallest particles (3nm to 50nm [4,5]), and is formed mainly through the nucleation of material from the gas-phase during exhaust cooling, although it can also be solid material such as ash. The accumulation mode consists of agglomerated solid particles formed from soot precursors, plus the extraction of material from the gas-phase [1], and has a typical size range of 30nm to 500nm [4].…”

Concurrently, the use of biofuel is increasing in the marketplace, and Euro5 specifies that reference fuel must contain a bio-derived portion.Work was carried out to test the effect of fuels containing different levels of Fatty Acid Methyl Ester (FAME) on particle number, size, mass and composition. Measurements were conducted with a Cambustion Differential Mobility Spectrometer (DMS) to time-resolve sub-micron particles (5-1000nm), and a Horiba Solid Particle Counting System (SPCS) providing PN data from a Euro5-compliant measurement system. To ensure the findings are relevant to the modern automotive business, testing was carried out on a Euro4 compliant passenger car fitted with a high-pressure common-rail diesel engine and using standard homologation procedures.It was found that using FAME decreased total PN emissions, by 16% over the Type I drive cycle (NEDC) for a 30% biodiesel (B30) compared to mineral fuel (B0). FAME also decreased accumulation mode PN and carbonaceous mass, by 20-30% for B30 versus B0, with a consequent reduction in Diesel Particulate Filter loading rate. A 25% increase in the nucleation mode PN was found when using B30 versus B0, and the higher molecular-weight organic mass fraction also increased. Increases in nitrogen oxides when using FAMEcontaining fuels were also confirmed.
