Performance and Emission Characteristics of Diesel Engine using Pine Oil Blends

Biodiesel was one of the alternative sources of energy. Bio-diesel was produced from various sources such as edible oils, non-edible oils, algae and animal fats. The aim of the project is to produce biodiesel from pine oil in order to displace diesel fuel to maximum extent level. The pine oil was blended with diesel as per ASTM standards. The pine oil has good atomization and lower viscosity compared to that of diesel. As a result, the pine oil can be blended directly with diesel fuel without trans-esterification. The various blends were tested in a single cylinder DI diesel engine coupled to eddy current dynamometer. The performance and emission characteristics of pine oil blends (B10 & B20) were compared with the results of base fuel. The results show that pine oil blends give better performance. The NOx emission level is increased compared to that of diesel, while the oxides of Carbon and Sulphur are decreased slightly.
