In the new study, Suzanne Paulson and colleagues note that scientists have known for years that aircraft emissions from fuel burned during takeoffs and landings can have a serious impact on air quality near major airports. Aircraft exhaust includes pollutants linked to a variety of health problems. ” Resources. Technol. ,

The nearly 70% drop in DPM coincided with actions taken over the years, beginning in the 1990s, to reduce diesel emissions. Also, the ambient and emissions trends for each of these four TACs were similar. Neighborhoods in freight corridors, including those near ports, will especially benefit. Credit: ACS, Propper et al.

The California Air Resources Board directed its staff to take steps to provide further locomotive and rail yard emission reductions beyond those achieved by existing US Environmental Protection Agency and state regulations and agreements. While we are pleased to have already reduced diesel emissions at the rail yards, it’s not enough.

Researchers at Iowa State have developed a new hybrid optimization control method to improve diesel engine emissions and performance. Validation of models, emissions testing, and rapid prototyping are just a few reasons that real engine testing must still occur despite so much progress in the realm of computational modeling.
