Cummins Power Generation, a division of Cummins Inc., last week announced that Doosan Infracore Portable Power has selected Cummins to provide diesel engines for its portable generator line. The Cummins engines will enable Doosan to comply with the Tier 4 emission regulations of the U.S. Environmental Protection Agency.
Tier 4 is the strictest EPA emissions requirement for off-highway diesel engines. The regulations set specific limits on the amount of pollutants, specifically oxides of nitrogen and particulate matter that can be released into the environment. The requirements are part of the federal Clean Air Act, whose purpose is to reduce air pollution because of its hazards to human health and the environment. In May 2004, as part of its Clean Diesel Program, EPA finalized a comprehensive rule to reduce emissions from non-road diesel engines. The rule consists of four tiers of emission standards; Tier 4, the final stage, is being implemented in two phases, Tier 4 Interim and Tier 4 Final.
Doosan Portable Power has successfully integrated Cummins’ 6.7- and 9-liter engines into its product line, and continues to work on the 4.5-liter integration.
“The overall Cummins value package proved to be the best solution for Doosan Portable Power,” said George Iarca, Cummins’ North America engine sales and marketing manager. “Part of the package includes 24/7 access to high-quality product support, which is a compelling advantage. We are delighted Doosan chose Cummins to help them meet their interim and final Tier 4 needs.”
Doosan Infracore, parent company of Doosan Portable Power, is headquartered in Seoul, South Korea. It offers a comprehensive range of products that support the mining, drilling, entertainment, industrial, and construction industries. The product line of Doosan Portable Power, acquired from Ingersoll Rand in 2007, includes portable air compressors, light towers and light compaction products, as well as mobile generators. Doosan has a combined network of more than 3,500 dealers worldwide and 20 manufacturing plants in the U.S., Europe and Asia.
