Diesel Fuel Composition Effect on Lubricity 2003-01-3568

Over the last few years the continuous air quality improvements to minimize the amount of toxical and harmful exhaust gases from diesel-powered vehicles has led to stricter diesel fuel specifications. The sulfur reduction in diesel fuel has resulted in poor fuel lubricity on account of deep hydrotreating that also reduces most polar compounds that provide natural lubricity. In this paper, we verify the diesel fuel composition effect on fuel lubricity, monitored by HFRR method. The variables used included sulfur and nitrogen compounds, aromatics compounds, density, viscosity, and so on. This study also involved a statistical analysis of an eighteen-fuel matrix.
