Cummins Inc., a supplier of diesel engines to the RV industry, has told the U.S. Environmental Protection Agency (EPA) that it is confident it will be able to satisfy the anti-pollution standards scheduled to go into effect a little over a year from now.
Cummins and four other engine manufactures signed a consent decree in 1998 promising the EPA that they would work towards lowering nitrogen oxide (NOX) emissions by 38% by October 2002.
The tougher EPA standard would apply to all on-highway products using Cummins engines, including motorhomes.
Cummins has “invested considerable resources” in technology to lower NOX emissions and Cummins Chairman Tim Solso added, “The costs associated with developing and refining the technology have been significant enough to alter the competitive landscape if any compliance delays are granted.”
Cummins, based in Columbus, Ind., recently asked Indiana’s legislature for a $35 million loan to help it pay some of its R&D costs.
Cummins believes it “achieved an important milestone” last month in the development of cooled exhaust gas recirculation (EGR) technology, which it believes is the only feasible technology for meeting the October 2002 emission requirements.
