Characterization And Prediction Of Blend Properties And Evaluation Of Engine Performance And Emission Parameters Of A Ci Engine Operated With Various Biodiesel Blends
Faculty of Engineering University of Malaya
The present research is aimed to investigate the feasibility of using palm (PB), mustard (MB) and Calophyllum biodiesel (CB) as renewable and alternative fuels. Biodiesels were produced from the respective crude vegetable oils and physicochemical properties of the biodiesel-diesel blends were graphically compared for all possible biodiesel blends at every 10% composition interval. By applying the curve-fitting method, equations were developed for predicting important properties, which show very close fit to the experimental data. This will help future research such as the optimization of blending percentage, engine combustion and performance and emission analysis. As up to 20% blends of biodiesels …
Evaluation Of N-Butanol As An Oxygenated Additive To Improve Combustion-Emission-Performance Characteristics Of A Diesel Engine Fuelled With A Diesel-Calophyllum Inophyllum Biodiesel Blend
Faculty of Engineering University of Malaya
Alexandrian laurel or Calophyllum inophyllum oil is considered as one of the most forthcoming non-edible biodiesel sources in recent years. In the present study, the relative improvement of an Alexandrian laurel biodiesel-diesel blend (AL20) was attempted with the addition of 5-10% n-butanol (by vol), which is often used as an oxygenated cold starting additive. Constant 80 Nm torque at variable engine speed, ranging from 1000 to 3000 rpm was chosen as the operating condition on a 4-cylinder turbocharged, water cooled diesel engine. Brake specific fuel consumption (BSFC), brake specific energy consumption (BSEC) and brake thermal efficiency (BTE) was measured to …
