Workshop summary: Effects of fuel composition on particulate emissions


HEI is pleased to announce the publication of the Executive Summary of proceedings from an HEI workshop that focused on the effects of fuel composition on particulate matter (PM) emissions. Approximately 45 researchers and government and industry representatives attended the workshop, which was held in Chicago in December 2016. Presentations included a detailed discussion of the impact on emissions from ethanol blending and aromatic contents of gasoline fuel and the use of gasoline direct-injection; other speakers discussed the real-world behavior of emissions. The Executive Summary includes an overview of regulatory and technology issues, results of laboratory tests for emissions from gasoline engines fueled with different ethanol blends, links between tailpipe emissions and real-world measurements, and future challenges.

The workshop program, presentations, and summary are available at
