Formerly, the Hydro-treated Vegetable Oil (HVO) blended fuels has been studied by running the New European Driving Cycle (NEDC) and found that the higher HVO blended fuel can suppress NOX, lowering the particulate matter (PM) while improving the vehicle fuel economy. The result also shown that the 20% HVO + 5%FAME blended with diesel fuel has been proven to compatible with the advance diesel engine technology via the severe engine durability tests and fuel injection system tests. Therefore, the effects of two paraffinic diesel fuels, which are Gas-to-Liquid (GTL) and Hydro-treated Vegetable Oil (HVO), on a common-rail DI diesel engine have been mainly focused in this work. The main objective of this work was to study the relationships between fuel properties and theirs combustion characteristics by analyzing cylinder pressure data and exhaust emissions intensively.
