A case study of real-world tailpipe emissions for school buses using a 20% biodiesel blend.
Numerous laboratory studies report carbon monoxide, hydrocarbon, and particulate matter emission reductions with a slight nitrogen oxides emission increase from engines operating with biodiesel and biodiesel blends as compared to using petroleum diesel. We conducted a field study on a fleet of school buses to evaluate the effects of biodiesel use on gaseous and particulate matter fuel-based emi...
متن کاملCurvature continuous blend surfaces
We describe a method to generate blend surfaces which t with continuous curvature to the primary surfaces. This blend surface is obtained as the bicubic tensor spline minimizing a variational problem. Among all the bicubic tensor splines which give a curvature continuous blend surface, the one is chosen which minimizes a bilinear functional. In Section 2 we summarize and extend the results of a...
متن کاملCombination of biodiesel-ethanol-diesel fuel blend and SCR catalyst assembly to reduce emissions from a heavy-duty diesel engine.
In this study, the efforts to reduce NOx and particulate matter (PM) emissions from a diesel engine using both ethanol-selective catalytic reduction (SCR) of NOx over an Ag/Al2O3 catalyst and a biodiesel-ethanol-diesel fuel blend (BE-diesel) on an engine bench test are discussed. Compared with diesel fuel, use of BE-diesel increased PM emissions by 14% due to the increase in the soluble organic...
متن کاملBiir / Poe Blend
Butyl rubber (polyisobutylene-co-isoprene (IIR)) is a very important commercial elastomer with many desirable physical properties, such as low air permeability and broad damping properties. The principal uses of this material are in the tire industry for the preparation of inner tubes and inner liners of passenger car tires. Despite these unique properties, there are some deficiencies associate...
متن کاملA Review Study of Performance and Emissions of CI Engine Fuelled with Blend of Biodiesel along with Fuel Nano Additiives
This paper describes the literature review of effect of different nano additives on performance and emission characteristics of diesel engine fuelled with different blends of biodiesel. This study is based on the previous research published articles. It was reviewed that by using nano additives with blend of biodiesel the performance characteristics were improved significantly but the exhaust e...
