Las Vegas (March 15, 2005) - Cummins Inc. (NYSE:CMI) announced today that its PowerMatch™ software optimizes engine performance and provides the OEM with unprecedented flexibility in installation. As part of the Cummins Advisor™ software suite for electronic engines, PowerMatch shapes torque curves and adjusts features of an electronic engine to match engine performance to customer needs.

"PowerMatch enables the Cummins application engineer to optimize the engine for the requirements of the application," said Cummins Vice President - Industrial Customer Engineering, Bharat Vedak. "In the past, power rating customization required time, cost money and valuable development resources. Now we are able to provide this value to our OEMs rapidly within a software environment while extending the capability of the machine to function at the highest levels of efficiency."

PowerMatch provides OEMs the ability to optimize engine performance to the machine and the work it is designed to perform. PowerMatch enables the OEM to provide performance enhancing benefits such as engine and equipment protection or to maximize fuel economy with the Alternate Torque Curve feature.

With PowerMatch High-Speed Governor Trim, the OEM can set maximum vehicle speed and power transfer rate for optimum performance. PowerMatch makes it possible for the OEM to custom tailor the engine in applications such as heavy lift trucks, to utilize the optimum calibration for both lifting and transporting its payload enabling faster, more efficient work. Additionally, savings in operational cost and reduced emissions can be made available through a Low-Speed Governor Trim setting with features such as an engine idle shutdown when a longer than specified amount of idle time occurs.

To provide a seamless fit between engine and equipment, PowerMatch takes into account the work environment, load factors, ambient temperatures and operating modes, and customizes the power curve and features of an electronic engine to a specific equipment model and/or application.

Cummins Advisor takes over from there and builds a virtual model to show how the electronic engine is installed in the equipment. Accounting for everything from load factors to fuel lines and operating climates to duty cycles, Advisor analyzes how these factors can affect overall reliability and equipment performance, and ensures that all systems work together for optimum performance.
