Cummins Engine Co. is making a bigger push into the off-highway engine market, trying to use technological advances made in its truck engines to meet environmental standards in the other market.

The company introduced a new product line of engines for the industrial market last Thursday. The off-highway engines primarily serve heavy equipment for agriculture, construction and mining. Officials with the Columbus, Ind., company say advances in the off-highway market should be able to offer advantages in its various transport engines, including truck, locomotive and marine engines."It flows both ways," said Ann C. Smith, a company spokeswoman. "We're continuing to try to upgrade and improve our entire engine line, regardless of its market."

The new equipment uses electronic sensors to reduce emissions, allowing it to meet environmental standards worldwide. It said that in addition to complying with new regulations anticipated in Europe and Japan, the new engines will perform at levels already adopted by the U.S. Environmental Protection Agency and the California Air Resources Board. New U.S. and California off-highway regulations take effect Jan. 1.

The company said the unveiling of a revamped off-highway product line is key to diversification and export efforts.

"In the past, we were basically a truck engine company that in our spare time made engines for the industrial market," Roberto Cordero, a Cummins group vice president of marketing, told the Indianapolis Star. "We have to be more than a truck-engine player in North America."

Sam Hires, another Cummins vice president, told the paper that the off- highway market "is one the most global of our business." He said about 45 percent of its sales come from exports.

The company has joint ventures with Komatsu of Japan and Wartsila Diesel International of Finland to develop engines for the export market.

"Our partnerships with Komatsu and Wartsila are important factors in our ability to expand Cummins' industrial product line for the worldwide marketplace so significantly," said James A. Henderson, Cummins' chairman and chief executive.
