“…Briefly, decreased PM 0.5 and BC concentrations were not seen during the 3-day experiment with NEXBTL as could have been expected on the basis of laboratory tests comparing NEXBTL and EN590 in heavy vehicle engines (Murtonen et al 2010). A major reason for this was probably that the trucks, having the best control of engine emissions with both fuels (EURO 5, all equipped with particle filter), had also the highest activities and largest fuel consumption during the test periods.…”

“…Besides efficient ventilation, that should be mandatory in all enclosed spaces with emissions, it is important to decrease the emissions through better engine technologies, higher fuel quality, and advanced after-treatment techniques. However, it should be noted that the introduction of novel engine and exhaust after-treatment technologies into vehicles used in underground mines may change not only the quantity but also the physico-chemical characteristics and toxic properties of emissions (Murtonen et al 2010;Jalava et al 2012). In this study, a 3 day experiment was conducted when fossil diesel fuel was changed to 100% renewable diesel fuel in all the vehicles in the underground mine.…”

“…A major reason for this was probably that the trucks, having the best control of engine emissions with both fuels (EURO 5, all equipped with particle filter), had also the highest activities and largest fuel consumption during the test periods. The loaders and bulldozers (EURO 4, no particle filter) with potential to show greater decreases in particulate emissions with NEXBTL (Murtonen et al 2010) were used much less than trucks. Thus, the overall change in particulate emissions with NEXBTL was likely small and might disappear with normal day-to-day variations in the activities.…”

Particulate matter (PM) from mining operations, engines, and ore processing may have adverse effects on health and well-being of workers and population living nearby. In this study, the characteristics of PM in an underground chrome mine were investigated in Kemi, Northern Finland. The concentrations and chemical composition of PM in size ranges from 2.5 nm to 10 mm were explored in order to identify sources, formation mechanisms, and post-emission processes of particles in the mine air. This was done by using several online instruments with high timeresolution and offline particulate sampling followed by elemental and ionic analyses. A majority of sub-micrometer particles (<1 mm in diameter, PM 1 ) originated from diesel engine emissions that were responsible for a rather stable composition of PM 1 in the mine air. Another sub-micrometer particle type originated from the combustion products of explosives (e.g., nitrate and ammonium). On average, PM 1 in the mine was composed of 62%, 30%, and 8% of organic matter, black carbon, and major inorganic species, respectively. Regarding the analyzed elements (e.g., Al, Si, Fe, Ca), many of them peaked at >1 mm indicating mineral dust origin. The average particle number concentration in the mine was (2.3 § 1.4) Ã 10 4 #/cm 3 . The maximum of particle number size distribution was between 30 and 200 nm for most of the time but there was frequently a distinct mode <30 nm. The potential origin of nano-size particles remained as challenge for future studies.

“…The engine was tuned and the NO x emission was reduced. Murtonen et al [9] used EN590 diesel fuel, FAME, HVO, and GLT fuels in the diesel engine and the results showed that NO x emission was high in FAME when compared with HVO and GTL. The other emissions were reduced compared with EN590 diesel fuel.…”

The experiments were conducted by using the hydrotreated refined sunflower oil as alternative fuel in a 4-stroke, stationary DI diesel engine at a constant speed of 1500 rpm. The effects of hydrotreated vegetable oil blends on diesel engine emission and performance were studied. The emission and performance were studied for different proportions such as HTSF B25 and HTSF B100 and at different loading conditions and comparison was made with petrodiesel. The emission and performance results of HTSF B25 and HTSF B100 showed that decrease in CO by 9% and 37%, HC by 42% and 55%, NO x by 10% and 18.18%, BSFC by 25% and 12.5%. The increase in brake thermal efficiency was by 10% and 38%. It was observed from the study that hydrotreatment of refined sunflower oil could be one of the best alternative fuels for the diesel engine. ª 2015 Faculty of Engineering, Alexandria University.

“…The urge to lower CO 2 emissions and to reduce fossil oil dependence has increased the use of biobased alternative fuels. New HVOs (paraffinic hydrotreated vegetable oils; e.g., NExBTL by Neste Oil) and synthetic F-T (Fischer-Tropsch) diesel fuels (e.g., GTL [gas-to-liquid] by Shell), which have very similar properties, are reported to lower the regulated as well as the unregulated engine exhaust emissions compared with regular diesel fuel (e.g., Tilli et al, 2010;Abu-Jrai et al, 2009;Heikkilä et al, 2009b;Knothe et al, 2010;Murtonen et al, 2010;Aatola et al, 2008). The absence of polyaromatic hydrocarbons (PAHs), the higher cetane number, and the lower distillation endpoint of HVO fuel compared with conventional EN590 (sulfur content <10 ppm) fuel are usually proposed as the main characteristics for lower NO x and PM emissions (Gill et al, 2011;Nylund et al, 2011).…”

The effect of intake valve closure (IVC) timing by utilizing Miller cycle and start of injection (SOI) on particulate matter (PM), particle number, and nitrogen oxide (NO x ) emissions was studied with a hydrotreated vegetable oil (HVO)-fueled nonroad diesel engine. HVO-fueled engine emissions, including aldehyde and polyaromatic hydrocarbon (PAH) emissions, were also compared with those emitted with fossil EN590 diesel fuel. At the engine standard settings, particle number and NO x emissions decreased at all the studied load points (50%, 75%, and 100%) when the fuel was changed from EN590 to HVO. Adjusting IVC timing enabled a substantial decrease in NO x emission and combined with SOI timing adjustment somewhat smaller decrease in both NO x and particle emissions at IVC À50 and À70CA points. The HVO fuel decreased PAH emissions mainly due to the absence of aromatics. Aldehyde emissions were lower with the HVO fuel with medium (50%) load. At higher loads (75% and 100%), aldehyde emissions were slightly higher with the HVO fuel. However, the aldehyde emission levels were quite low, so no clear conclusions on the effect of fuel can be made. Overall, the study indicates that paraffinic HVO fuels are suitable for emission reduction with valve and injection timing adjustment and thus provide possibilities for engine manufacturers to meet the strictening emission limits.Implications: NO x and particle emissions are dominant emissions of diesel engines and vehicles. New, biobased paraffinic fuels and modern engine technologies have been reported to lower both of these emissions. In this study, even further reductions were achieved with engine valve adjustment combined with novel hydrotreated vegetable oil (HVO) diesel fuel. This study shows that new paraffinic fuels offer further possibilities to reduce engine exhaust emissions to meet the future emission limits.
