LOUISVILLE, Ky. — Cummins says that it has achieved an important milestone in the application of existing combustion technologies and hardware for its industrial engines required to meet the new emissions standard.

“Cummins serves a broad range of off- and on-highway markets, each having different customer requirements. We have invested in the technologies that matter most so we can apply the best technical solution to meet customer needs in each of the markets we serve,” says John Wall, Cummins vice president and chief technical officer.

Cummins says it has successfully demonstrated it will be able to meet the Tier 3 requirements without the addition of aftertreatment devices or other costly hardware and will launch engines prior to the 2005 standard.

The engine company’s solution for achieving these standards enables customers to use existing engine platforms with electronic fuel systems, but without the addition of what Cummins calls expensive and unproven aftertreatment devices using fuel that can include up to 5,000 ppm of sulfur. Sulfur has been proven to significantly degrade aftertreatment performance.

All of the emissions-related changes at Tier 3 will be virtually transparent to the OEMs and the end-users with existing fuels, and will provide the lowest total costs at these standards.
