The Environmental Protection Agency (EPA) and International Truck and Engine Corp have announced a testing and development partnership to advance the EPA's clean diesel combustion (CDC) technology for low-emission diesel engines. They said the “commercial viability” of CDC will be determined jointly.

This new technology uses in-cylinder control of nitrogen oxide (NOx) emissions to reduce or eliminate the need for aftertreatment related to NOx. International is evaluating CDC for use in its product line, starting with its V-6 diesel for SUVs and pickup trucks, which is being tested at EPA labs.

Through the partnership, both organizations will seek to incorporate environmentally sound technologies in an economical package.
