ABSTRACT
The dual fuel technique offers the advantage of easy conversion of the diesel
engine to work on the dual fuel mode with little engine modifications. In this
mode, the primary fuel (turpentine) is inducted along with inlet air stream and
the pilot fuel (diesel) is injected through the regular injection system. The primary
fuel (turpentine) shared the maximum energy in the power production but the
pilot fuel shared only a least part and act as an ignition source. The engine with
this facility has been operated under various load conditions and at various
turpentine energy shares. The energy share that provides better performance
has been identified and compared with diesel fuel operation. From the obtained
results it was proved that this engine offered higher BTE at full load and smoke
free operation at all loads. The CO and HC emissions were higher and operated
with very low NOx emission at all loads. The results also proved that the dual
fuel operation successfully replaced 75% of diesel usage with turpentine fuel.

Keywords: Turpentine, dual fuel engine, energy share, brake thermal efficiency,
