Abstract
FORTY-SIX EXPERIMENTAL DIESEL FUELS have been tested in a modern automotive diesel engine, and the effect of fuel characteristics on particulate emissions, gaseous emissions, and fuel economy has been studied. Regression analysis of results established a relationship between particulate emissions and two fuel characteristics: (1) aromatic content and (2) volatility, especially as described by the 90% boiling point. Particulates could be reduced by lowering either aromatic content or 90% boiling point. The foregoing conclusions were based on a weighted five-load dynomometer schedule but appear to be confirmed by limited vehicle testing on the Federal Test Procedure.
