Timeline: A Legacy of Leadership

International’s long standing commitment to diesel technology that improves engine performance and helps the environment is a matter of public record.

For more than 60 years, International has produced quality engines that meet customer demands, while demonstrating environmental responsibility in meeting — in fact, anticipating — rising public interest in cleaner air.

International has always been a leader in developing new diesel technology that improves engine performance while addressing environmental impact.

Here are highlights of the International clean-air record so far:

2010

Navistar becomes the only company to offer advanced EGR (exhaust gas recirculation) to meet new and strict emissions standards.

2008

Navistar becomes the first Original Equipment Manufacturer (OEM) to earn certification from the U.S. Environmental Protection Agency (EPA) as both a SmartWay Transport Partner and a SmartWay Manufacturer; Navistar develops first and only diesel-hybrid, plug-in school bus.

2007

Navistar first to enter “line production” of hybrid vehicles; Navistar wins prestigious Blue Sky Award for its contributions to the commercial development of diesel-hybrid technology.

2006

Nation’s first hybrid school bus is unveiled in New York by IC Corporation, subsidiary of Navistar.

2005

International Offers Class-8 Engine, Certified to 2007 Emissions Standard.

2004

Announces technology path to achieve 2007 federal standards for particulate, hydrocarbon and nitrogen oxides emission reductions in new diesel trucks and school buses.

2003

Introduces Green Diesel Technology® retrofit kits to reduce particulate emissions in late-model school buses and trucks.

2002

International introduces its next generation fuel system based upon digital valve technology from Sturman Engine Systems, LLC. as well as other technologies that will assist in meeting clean air goals.

2000

International develops a new, low-emission Green Diesel Technology school bus — the first diesel with emissions equal to natural gas.

1999

International demonstrates its Green Diesel Technology® vehicle to the Environmental Protection Agency (EPA), California regulators and the public: no smoke, no fumes, dramatically lowered pollutants.

1998

The EPA gives International 100 percent approval for its 1999 model engines in meeting emissions standards. International is the only U.S. diesel engine manufacturer to receive such approval at that time.

1996

International becomes the first diesel engine manufacturer to show it could meet federal emissions standards that are set for 2004.

1994

International introduces its HEUI technology.* This technology is developed to improve emissions control, fuel economy and performance.

1989

International releases the first smokeless diesel engine — five years ahead of the U.S. Environmental Protection Agency’s deadline.

*HEUI stands for Hydraulically actuated, Electronically controlled Unit Injector technology.
