Safflower Biodiesel Blends with Eurodiesel in Common Rail Diesel Engine Exhaust Emission Effect
In the present study, the effects of biodiesel obtained from safflower oil through transesterification and Eurodiesel blends on engine exhaust emissions were examined in a four-stroke, common-rail fuel system, water-cooled, fourcylinder diesel engine. The biodiesel used in this study was produced from safflower oil through transesterification. Using this biodiesel and diesel fuel, fuel blends of B7 (7% safflower methyl ester-93% diesel fuel in volume), B40 and B80 fuels were prepared. Experiments were conducted on the engine by using these fuel blends.
Public Policy and Biofuels: Energy, Environment and Food Trilemma
Current policies in energy sector address issues including renewable energy supplies and encourage more efficient energy use. As expected biofuels can reduce dependence on imported fossil fuels, strengthen political and economic security, revitalize the economy by increasing demand for agricultural products. At the same time biofuels production can threaten food safety by making influence on price and demand for agricultural commodities. The article examines the influence of public policy in the sphere of biofuel on energy, environment and food security.
