Emission characteristics of a heavy-duty diesel engine operating on neat gas-to-liquids GTL (1&2) of different fuel characteristics were investigated and a comparison was made with those of diesel fuel. The effect of GTL on the emissions of a heavy duty diesel engine was carried out. The results showed that the engine fueled with GTL (1) & (2) had some variations compared with the one fueled with diesel fuel. Under the load characteristics, the nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbon (HC) emissions can be decreased when operating on both GTL. Compared with GTL (1) & (2) characteristics, the results showed that the engine operating on GTL (2) can reduce NOx, CO, and HC better than the engine operating on GTL (1), these were due to its high cetane number, low aromatic content, low sulfur content, low kinematic viscosity, low density and high heating value.
