Cummins Launches Sulfur Tolerance Kit For Tier 4 Diesels

By Mike Brezonick21 January 2016

Cummins Inc. announced that its Sulfur Tolerance Kit, designed to allow export of emissions-compliant equipment into global regions without access to ultra-low sulfur diesel (ULSD), is now available.

Cummins Sulfur Tolerance Kit is intended to increase resale value and marketability of used equipment that meets U.S. Environmental Protection Agency (EPA) Tier 4 and European Union (EU) Stage 3b/Stage 4 standards by allowing its export into countries without access to ULSD fuel.

"The release of Cummins Sulfur Tolerance Kit broadens resale opportunity for customers, allowing them to sell used emissions-compliant equipment into non-emissionized countries," said Hugh Foden, Cummins executive director – Off-Highway Business. "Additionally, the kits increase the flexibility of Cummins products, making them capable of operating globally, and ensuring that subsequent owners experience the same reliability and durability that customers expect from Cummins."

Meeting emissions regulations in North America and Europe requires the use of ULSD fuels, which contain fewer than 15 parts per million (ppm) of sulfur, to reduce particulate matter (PM), soot and sulfur dioxide (SO2). Cummins Sulfur Tolerance Kit allows an engine to be operated on fuels containing as much as 5000 ppm sulfur by removing aftertreatment components and modifying the engine control system, enabling a second life for the engine outside of regulated regions.

Currently available for the Tier 4 interim/Stage 3b QSB6.7, QSL9 and QSX15 engines, and then extending across the entire product lineup this year, the Cummins Sulfur Tolerance Kit includes new engine calibration and hardware, depending on engine model, and is solely intended for used engines that are exported into non-regulated regions.

Information on the purchase and installation of the Sulfur Tolerance Kit is available from Cummins distributors, by e-mailing Cummins Care Europe (cceurope@cummins.com) or online at cumminsengines.com.
