Environmental Mission

Cummins Power Generation Supports New EPA Emissions Regulations

The United States Environmental Protection Agency (EPA) is developing new emissions standards called New Source Performance Standards for stationary and spark-ignited generator sets. The regulatory proposal for diesel engines was finalized in June of 2005. The proposal for spark-ignited engines will be completed in June 2006.

Cummins Power Generation supports these new emissions standards and is developing products that, at a minimum, comply with these standards. For further information about these standards and our products affected by them, please read our EPA Emissions information.

Our Environmental Commitment

Cummins Power Generation is committed to providing products that minimize their impact on the environment. This commitment is reflected in our current products and in our new technologies used in cells and turbines. We are developing cleaner combustion techniques with natural gas and diesel reciprocating engine generators, plus factory-integrated exhaust aftertreatment that allows these products to meet stringent global emissions standards.

Cummins Power Generation is improving the fuel efficiency of all its engines—because less fuel consumed means fewer emissions overall. Sophisticated electronic engine controls have virtually eliminated visible smoke, and better engine design has reduced lubricating oil consumption to only 0.15 percent of fuel consumed—the best in the industry. Our lean-burn gas engine generators used in combined heat and power (CHP) applications significantly reduce wasted energy and overall emissions.

To minimize other operational impacts, our generators are designed to exhibit inherently low noise and low vibration. With optional advanced sound-attenuated enclosures, even large generator sets can be located near residential areas without affecting the local environment.

Cummins Power Generation is part of Cummins Inc., a corporation recognized for its environmental progress, and for being the first engine manufacturer to meet the on-highway standards established by EPA in 2002. A major part of its $240 million annual research and engineering budget is dedicated to environmental fuel-efficiency improvements.
