1、Biodiesel as Blending Component for Diesel Fuel - its Application and Benefits,Biodiesel Conclave 5th Nov., 2005 India Habitat Centre, New Delhi,R.K.Malhotra IOC R cold weather performance may be affected Storage stability and material compatibility could be of concern need further investigation.,Ef

2、fect of Biodiesel Blending on Diesel Properties,Effect of Biodiesel on Lubricity,Addition of even 2% Biodiesel helps in significant improvement of lubricity of Diesel,Starting time with neat Diesel and Bio diesel -blend (B20),Startability found poorer in sub-zero conditions,Performance results on a

3、Multicylinder Engine,Biodiesel blends (B20) Diesel,Torque found to improve in some cases,Smoke Vs RPM,BSFC Vs RPM,Fuel Economy Vs. Vehicle Speed,SFC Vs. Vehicle Speed,Smoke Vs. Vehicle Speed,Mass Emission Results on Bio-diesel Blends,CO & Particulates reduce with Biodiesel,Mass Emission of Carbon Mo

4、noxide, g/km with Diesel & B20 Blends,CO substantially lower with Biodiesel & use of Cat Convertor,Percentage Reduction of CO Mass Emissions with and without Catalytic Converter & Bio-diesel,Mass Emission of Oxides of Nitrogen, g/km with Diesel & B20 Biodiesel Blend,Oxides of Nitrogen increase with

5、Biodiesel,Mass Emission of Particulate, g/km with Diesel & B20 Biodiesel Blend,Particulates decrease with Biodiesel & Cat Converter,Total Aromatics and PAH Distribution in Particulate Matter,Total aromatics in particulates lower with Biodiesel. Polyaromatic hydrocarbons found further lower.,Particul

6、ate Number Concentration for Diesel and B20 while driving as per Indian Driving Cycle (IDC),Small size particles found lower with Biodiesel Blends,Conclusions,Bio-diesel blending in Diesel improves most of the Fuel properties Engine & Vehicle performance found comparable except the cold startability in sub-zero conditions Mass emissions of carbon monoxide and particulates found lower with Biodiesel blends, but NOx increased Catalytic converter along with Biodiesel helps further reductions of CO & particulates Small size respira
