Navistar Engine Timeline
2001: The Environmental Protection Agency enacts a rule requiring a 95 percent reduction in the emissions of nitrogen oxide from heavy duty diesel engines. Manufacturers have until 2010 to comply.
2010: Navistar’s engines, created using an EPA patented process, still do not meet requirements, so it uses banked emissions credits to buy more time.
January 2012: After Navistar predicts it will run out of credits, the EPA passes a rule to permit noncompliant manufacturers to pay a penalty in exchange for the right to sell noncompliant engines.
May-June 2012: A group of competitors sue the EPA, arguing that the fines Navistar pays are too lenient and that
they were not given notice of the ruling. The court rules against the EPA.
July 2012: On July 6, Navistar announces a a new engine proposal called ICT-Plus, which will combine the company’s current engine technology with EPA-compliant technology used by competitors.
August 2012: Navistar forms a partnership with Cummins to create the ICT - plus system.
