SwRI engineers help develop post-refinery diesel treatment that overcomes soot/NOx tradeoff for cleaner burning fuel

Green Car Congress

Southwest Research Institute (SwRI) is helping a client develop a simple post-refinery treatment process that reduces exhaust emissions from diesel engines by overcoming the soot/nitrogen oxides (NO x ) reduction trade-off that has plagued engine researchers for decades.

Odfjell first to install suction sails on deep-sea chemical tanker; bound4blue’s eSAIL system

Green Car Congress

The systems have been conceived as a complementary propulsion system, which produce effective thrust from existing winds, reducing the main engine power required and, therefore, delivering fuel consumption and pollutant emissions reductions of up to 40%. The suction fan is a standard axial compressor driven by an electric motor.

National Academies report finds EPA’s controlled human exposure studies of air pollution are warranted

Green Car Congress

CHIE participants are exposed to one or several common air pollutants usually for a few hours at concentrations that are not expected to produce adverse responses. The NAAQS process has broad health importance because it regulates the outdoor air concentrations of those pollutants. 2009 to Oct.

CRC ACES Phase 2 report finds emissions from modern heavy-duty diesels well below required levels

Green Car Congress

2010 engines emissions reduction relative to 2010, 2007, and 2004 US emission standards. For a number of the most important pollutants, levels were substantially lower than required by regulations. These reductions came while emissions of fine particles were also 92% lower than the 2010 standard 99% lower than 2004 emissions.

ACEEE report recommends steps toward international alignment of heavy-duty vehicle efficiency standards

Green Car Congress

A new report published by the American Council for an Energy-Efficient Economy (ACEEE) recommends the international harmonization of fuel efficiency and/or greenhouse gas emissions standards for heavy-duty trucks and buses. This report explores whether and how heavy-duty standards programs could be better aligned across regions.
