arbcombo -- ARB Research Seminar: Evaluating Technologies and Methods to Lower Nitrogen Oxide Emissions from Heavy-Duty Vehicles
Posted: 01 Jun 2017 08:22:10
Christopher Sharp and Ian Smith Southwest Research Institute, San Antonio, Texas. Thursday, June 15, 2017 at 10:00 a.m., PDT (WEBCAST) Sierra Hearing Room, 2nd Floor, CalEPA Building 1001 I Street, Sacramento, California The 2010 emission standards for heavy-duty engines have established a limit for oxides of nitrogen (NOX) emissions of 0.20 g/bhp-hr, a 90% reduction from the previous emission standards. However, it is projected that even when the entire on-road fleet of heavy-duty vehicles operating in California is compliant with the 2010 NOX emission standards, the upcoming National Ambient Air Quality Standards (NAAQS) requirements for ambient particulate matter and ozone will not be achieved in California without further significant reduction in NOX emissions from the heavy-duty vehicles. The main goal of this project was to demonstrate that modern heavy duty engines can achieve a target of 0.02 g/bhp-hr for tailpipe NOX emission, which represents a 90% reduction from the 2010 standard, with currently available control technology. An additional goal of the project was that the final configurations of engine and aftertreatment systems should be consistent with a path toward meeting current and future heavy-duty greenhouse gas (GHG) and fuel economy standards.
