In this paper, the authors evaluated the effect of blending biodiesel and ethanol into conventional diesel fuel on exhaust gas emissions, and showed that the results showed a significant reduction in NOx emissions in new engines with an increased ethanol concentration.Abstract:
The monoalkylesters of fatty acids derived from vegetable oils or animal fats, are
considered as an attractive alternative fuel for diesel engines This interest is based on a number of
properties of biodiesel including the fact that it is produced from a renewable resource and its
potential to reduce exhaust emissions Although several studies have been performed on biodiesel
emissions, the results have been contradictory with some studies reporting a reduction of NOx
emissions while others reporting an increase Also, thus far, there has been no promising method on
record which has been successful in reducing biodiesel related NOx emissions The objective of this
study was to evaluate the effect of blending biodiesel and ethanol into conventional diesel fuel on
exhaust gas emissions Ethanol could be added to diesel in limited quantities along with biodiesel
since biodiesel stabilizes the ternary system by acting as an amphiphile This paper illustrates the
emission characteristics of diesel-biodiesel-ethanol (DBE) fuel blends on one use and two brand new
engines DBE is a new form of oxygenated diesel fuel blend and have a potential to reduce NOx emissions and to be an alternative to diesel fuel The blend ratio (diesel: Biodiesel: ethanol) by
volume used in this study was 70:25:5, 70:20:10 and 70:15:15 The results from the operation of
diesel engine with DBE showed a significant reduction in NOx emissions in new engines with
increased ethanol concentration where as with the old engine under similar conditions, an increased
NOx emissions profile was observed CO emission increased with increasing ethanol proportion in
the blends in both new and old enginesread more

The effect of ethanol–diesel–biodiesel blends on combustion, performance and emissions of a direct injection diesel engine
TL;DR: In this article, the authors examined the influence of the ethanol and RME addition to diesel fuel on start of injection, autoignition delay, combustion and maximum heat release rate, engine performance efficiency and emissions of the exhaust when operating over a wide range of loads and speeds.

Impact of n-butanol as an additive with eucalyptus biodiesel-diesel blends on the performance and emission parameters of the diesel engine
TL;DR: In this paper, the influence of butanol (Bu)-biodiesel (B)-diesel fuels on the diesel engine was examined and it was found that slight increase in brake power and higher brake specific fuel consumption (BSFC) are attained with butanol-biodiel-diesel- fuels, while brake thermal efficiency was decreased.
Performance and emission characteristics of diesel engine fuelled with ethanol-diesel-biodiesel blend.
TL;DR: In this paper, the effect of simultaneous ethanol and RME addition into diesel fuel on brake mean effective pressure (bmep ) of the engine, its brake specific fuel consumption (bsfc ), the brake thermal efficiency (�e) and emission composition changes, including NO, NO 2, NO x, CO, CO 2, HC and smoke opacity of the exhausts.
