“…In contrast to these beneficial aspects, alterations of the fuel's viscosity and/or the formation of precipitates can cause major problems and, in extreme cases, even a complete failure of the injection system. Moreover, difficulties with FAME during the cold-start phase have repeatedly been described in the literature, which can be explained by the cold filter plugging point (CFPP) of FAME (Moeltner et al, 2017). In addition, problems during the cold-start are caused by the comparable low vapor pressure of the fuel, which leads to an increased input of FAME into the engine oil, particularly during regeneration phases of the diesel particulate filter (DPF), where post injections occur.…”

“…In addition to the reduction of CO 2 -emissions and the independence of fossil energy carriers, the application of alternative diesel fuels or blends provides many advantages. Particularly, the use of fuel blends containing hydrotreated vegetable oils (HVO) and/or biomass to liquid (BtL) are known to emit fewer regulated emissions, such as carbon monoxide (CO), hydrocarbons (HC), and particulate matter (PM) (United States Environmental Protection Agency and Department of Transportation, 2010a,b;Moeltner et al, 2017).…”

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.

Curb CO 2 emissions' is a common expression today and it will be heard even more frequently in the future. Biofuels have attracted attention for many years, and recently this attention has been directed, in particular, to biofuels in heavy-duty vehicles. This sector contributes to a significant quantity of emissions in Brazil. This class of fuels -biodiesel, fatty acid methyl esters (FAMEs) -has an established industry in Brazil. However, the limited capacity for the production of biodiesel, and the limitations imposed by its properties, make it difficult to expand the industry. Thus, hydrotreated vegetable oils (HVOs) have emerged as a more environmental friendly fuel and a potential alternative to cut emissions in the transportation sector. To identify ways to use such fuels in Brazil, this study reviews environmental indicators for diesel, biodiesel, and HVO, and compares then using a composite score. Based on specific emission factors, scenarios for the use of HVO are evaluated in terms of emissions avoided, potential granting of decarbonization credits, and feasibility for investment. The results in one of the scenarios evaluated show that 0.5 decarbonization credits can be granted for each liter of HVO consumed in Brazil. There is room for profitability in all of the scenarios. This work also shows that Brazil has the necessary public policies to foster biofuels on a large scale, and, with blend mandates being reformulated, the country could avoid emissions of over 12.9 million CO 2 tons per year in the transport sector.
