4. Clean Air Facts - Emission Controls for Diesel Engines
Recently, health experts in the U.S. have identified serious health risks associated with emissions from diesel engines, especially oxides of nitrogen (NOx) and particulate matter (PM) emissions. Cost-effective diesel exhaust control options such as catalysts and particulate filters are available which can significantly reduce emissions from diesel-powered trucks, buses, and off-road equipment.

ACEA data of the sulphur effect on advanced emission control technologies
The European vehicle manufacturers have collected their most recent in-house data demonstrating the effect of sulphur on advanced emission control technologies. The purpose is to respond to the minireview launched by the European Commission. The objective of the review is to provide evidence for a proposal to amend, if appropriate, the current legislation concerning the sulphur content of gasoline and diesel fuels.

Catalyst-Based Diesel Particulate Filters and NOx Adsorber: A Summary of the Technologies and the Effects of Fuel Sulfur
In order to achieve the proposed reductions in harmful emissions from the diesel engine, an engineered systems approach will be needed to integrate and combine advanced engine designs, advanced exhaust control technologies, and improved diesel fuel quality.
Diesel Emission Control - Sulfur Effects (DECSE) Program - Final Report: Diesel Oxidation Catalysts and Lean-NOx Catalysts
The Diesel Emission Control - Sulfur Effects (DECSE) Program is a joint government/industry program which aims to determine the impact of diesel fuel sulfur levels on emission control systems whose use could lower emissions of nitrogen oxides (NOx) and particulate matter (PM) from on-highway trucks from the 2002-2004 model years.
