Methanol and glyceride contents of Egunsi melon oil, its biodiesel and blends with diesel fuel

Biodiesel is gradually being accepted worldwide as suitable alternative fuel for diesel engine. Rigorous purification is however required to meet the American Society for Testing and Materials (ASTM) and European Union (EU) standards for biodiesel because of unfavorable properties and the multitude of feed stocks with different properties that can be used. Two of such impurities that must be kept within limits are...

Numerical investigations on the use of waste animal fats as fuel on DI diesel engine

Biodiesel is a promising alternative to petroleum-based diesel fuel because it is renewable and its extensive use in unmodified engines has proved to be very successful. However, its future use may be limited by the higher oxides of nitrogen (NOx) emissions that are typically generated relative to petroleum diesel. This paper deals with the numerical investigations on the use of Waste Animal Fat (WAF) as alternative...
