Abstract
On a global scale environment concern, energy saving and clearing up of air pollution is one of the most important subjects in the world today. A very efficient and promising approach to rapidly improve the pollutant emission behavior of existing vehicles fuel is to optimize the diesel fuel composition with regard to reduced pollutant formation and, in particular, soots emission. Fuel quality and automotive technology are inseparably linked. New technologies that will enable to reduction of diesel engine exhaust emissions, specially particulates and NOx, can be introduced only if fuels of a suitable quality are made available.
The paper gives a review of the effect of sulfur and aromatics interaction affecting DI diesel engine emissions particularly particulate and NOx emission. Diesel engine emissions were measured in accordance with ECE R 96 8-mode cycle and ECE R49 Regulation, 13-mode cycle.
Obtained test results show that exhaust emissions are strongly sensitive by the sulfur content in fuel and then by aromatic content.
