Abstract
As bio-fuel is carbon neutral, it is considered to be an effective fuel for reducing CO2. Bio hydrofined diesel (BHD) seems to have a high potential for use as an automotive fuel because of its zero aromatic content and higher oxidation stability. This paper describes the effects of BHD on material compatibility and emissions using the latest heavy-duty diesel engine. It shows that the effects of a BHD-blended fuel are almost the same as conventional diesel fuel. As a result, BHD fuel is demonstrated to be an appropriate fuel for diesel engine vehicles.
