Experimental Investigation for A Diesel Engine Operating on Fishcher-Tropsch Diesel Fuel

The combustion and emission characteristics of a single cylinder direct injection diesel engine operating on Fishcher-Tropsch(F-T) diesel fuels and No.0 diesel fuels were studied.Results showed that compared with operating on No.0 diesel fuels at all tested speed-load points,effective thermal efficiency,economical efficiency and emissions for the diesel engine operating on fuels combination containing 50%,75% and 100% F-T diesel fuels were greatly improved. Thermal efficiency increased by 4.92%,5.22% and 6.38% respectively.Specific fuel consumption reduced by 2.15%,2.61% and 2.87% respectively.NO_x emissions reduced by 78.2%,85.6% and 90.1% respectively.CO emissions reduced by 91%,93.7% and 96.5% respectively.CO_2 emissions reduced by 77.6%,82.3% and 87.5% respectively.Exhaust temperatures of 100% F-T diesel fuels reduced by 3.5%.Experimental results demonstrate that F-T diesel fuel is an excellent cleaning alternative fuel for diesel engines.
