Optimization of NOx Emission from Soya Biodiesel Fuelled Diesel Engine using Cetane Improver (DTBP)
Within the depleting resources of fossil fuels and the increase in their price, in the recent past a lot of interest has been given to the use of plant oil specially the non-edible oil and its ester (biodiesel). Although the use of biodiesel in place of diesel has resulted in much lesser tail pipe emission, a substantial increase of NOx is reported by several researchers. It may be due to low c...
متن کاملCetane Number and Thermal Properties of Croton Oil , Biodiesel , 1 - Butanol , and Diesel Blends
Vegetable oil derived fuels for diesel engines are becoming important as alternative to petroleum diesel fuels due to their environmental friendliness and availability. Ignition quality in compression ignition (CI) engines is influenced by thermal characteristics and fuel properties. In this study, the effects of vegetable oil transesterification and vegetable oil-1-butanol-diesel blend on fuel...
متن کاملChemical Kinetics of Cetane Number Improving Agents
INTRODUCTION The increasing demand for diesel fuels has resulted in the use of greater percentage of cracked distillates having poor ignition properties. The ignition properties of diesel fuels can be rated in terms of their cetane number and diesel fuels having low cetane number may have poor ignition properties such as diesel knock, difficulties to start engines in the cold weather and so on....
متن کاملA Green Method for Determination of Acid Number of Biodiesel
Neste trabalho é proposto um método simples e verde para a determinação do índice de acidez do biodiesel. A amostra é dissolvida em solução 1:1 v/v etanol:água, evitando a mistura tolueno:isopropanol:água (1:0,95:0,5 v/v/v) usada nas normas atuais. A titulação é realizada com uma solução aquosa de NaOH 0,02 mol L. O método foi comparado com o da ABNT NBR 14448, que é similar ao do ASTM D 664 e ...
متن کاملA new method for determining the acid number of biodiesel based on coulometric titration.
A new method is proposed for determining the acid number (AN) of biodiesel using coulometric titration with potentiometric detection, basically employing a potentiostat/galvanostat and an electrochemical cell containing a platinum electrode, a silver electrode, and a combination pH electrode. The method involves a sequential application of a constant current between the platinum (cathode) and s...
