Diesel engines, in combination with modern turbocharging and common railinjection systems, feature comparably high efficiencies coupled with favorable torquecharacteristics. Therefore, besides the utilization in commercial vehicles, diesel enginesgained large market shares within the passenger car sector. The European Unionregulates the deployment of biofuels and has issued several targets throughout theyears; focusing on the urge to reduce carbon dioxide emissions, as well as on thegrowing demand for independence of fossil energy sources. This contribution presentsinvestigations on fuel blends containing different shares of biomass to liquid, hydrotreatedvegetable oils, and fatty acid methyl ester applied in a state of the art light-dutydiesel engine. In general, the reviewed fuel blends exhibit good applicability for theutilization in the test engine with default settings of injection timing and exhaust gasrecirculation; adjustments on the just mentioned parameters unveil further potential interms of emissions and efficiency. Particularly the potential of biomass to liquid blendsto partly mitigate the tradeoff between particulate matter and nitrogen oxides deservesdistinct attention.
