Comparison of Conventional Diesel and Fischer-Tropsch Diesel Fuels for HCCI Combustion
Conference contribution, 2006

Engine tests were performed with Swedish low sulfur Diesel, European EN 590 Diesel and two natural gas-derived Fischer-Tropsch Diesel fuels in a light-duty single-cylinder engine to compare their emission, fuel consumption, and combustion characteristics. The engine was operated in HCCI combustion mode with multiple injections and different injection timings. The combustion was phased to a constant CA50 for all operating points by adjusting the amount of EGR. Low soot emissions are expected with HCCI, and no significant differences between the various fuels were detected in this respect. However, NOx emissions were lower for the F-T fuels than the other fuels, due to their high cetane number and higher EGR requirements.
