Abstract
Six specially blended diesel fuels were tested in an open chamber TACOM-LABECO single cylinder diesel engine at turbocharged conditions, to determine if the chemical composition of the volatile fraction of the fuels had a significant effect on performance and emissions. The tests show that for this engine, which has a moderately high swirl and a four hole nozzle, the effects are very small. Additional tests were run, with these same fuels, in a homogenous autoigniting mode to determine if ignition trends were similar to those produced by the heterogeneous diesel ignition. The ignition delay trends were found to follow the same pattern, reinforcing the conclusion that the fuel combustion in the diesel was not significantly affected by distillation effects during the vaporization process.
