With modernization and increase in the number of automobiles worldwide, the consumption of diesel and gasoline has enormously increased. As petroleum is nonrenewable source of energy and the petroleum reserves are scarce nowadays, there is a need to search for alternative fuels for automobiles. Turpentine oil has been used in direct injection CI engine as an alternate fuel has similar properties as that of diesel. Acetylene is also a very good alternate fuel. In the present work, blend of different proportion of turpentine and diesel use in the diesel engine in which Acetylene was also introduced through intake manifold at a point closer to the intake valve by a non-return valve arrangement through a flame trap. The flow of acetylene was controlled 3 liters per minute by needle valve and was measured by a calibrated gas flow meter. The experiment run set was prepared by design of experiment in which L9 orthogonal array used for the experiment where different blend proportion, injection pressure and the load are the variable parameters and FC, SFC.
