International Truck and Engine Corporation reached an agreement with the US Environmental Protection Agency (EPA) to evaluate “Clean Diesel Combustion”—an in-cylinder NOx control technology which is being developed by the EPA. The partnership was announced at International’s engine technical center in Melrose Park, IL, by the EPA administrator Leavitt and Navistar International Corporation’s chairman Ustian.

“This new partnership with the EPA enhances our opportunity to deliver a low-cost diesel solution that will meet 2007 light-duty standards and 2010 heavy-duty standards. This solution in turn will help diesel reach its potential as the one technology that can help America quickly improve its auto mileage, reduce its use of foreign oil and cut the carbon dioxide emissions that have been linked to global climate change,” said Ustian.

The “Clean Diesel Combustion” technology uses in-cylinder control of nitrogen oxides (NOx) to reduce or eliminate entirely the need for NOx aftertreatment. It was originally developed by the EPA at its National Vehicle and Fuel Emissions Laboratory in Ann Arbor, MI, together with industrial partners. The program targets an engine of NOx emissions below 0.2 g/bhp-hr and/or 0.2 g/mi. Selected performance data of an EPA prototype engine developed in cooperation with FEV can be found in the DieselNet Technology Guide.

The technology relies on improvements in several diesel engine systems, including fuel injection, air management, turbocharging and combustion. International will evaluate the technology in its light-duty V6 diesel engine.

The partnership between EPA and International takes place through a Cooperative Research And Development Agreement (CRADA).
