Cummins Marine

Cummins Marine is continuing its recent pace of introducing engine products to the commer- cial marine industry that have been designed and built with the latest technical advancements.

The addition of three new, powerful ratings for its K38 engine is a good example of the progress being made. The engine is now available at ratings of 1,300 bhp (970 kW) for medium con- tinuous duty applications. A new Holset turbo- charger, low-temperature aftercooling and a new gallery-cooled piston are among the major im- provements made to the engine. Typical applica- tions for the K38 include fishing vessels, tugs and barges, crewboats and ferries. Because of its more efficient fuel consumption (.331 BSFC at rated speed for 1,200 bhp) the engine also fea- tures a lower annual operating cost. "We have thousands of KV engines in operation world- wide, and introducing new technology is the way we reinforce our commitment to the marine market," said Paul Rabe, vice president and general manager of Cummins Marine. Cummins also offers a broad application range with avail- able ratings from 64 to 1,384 bhp (47-1,033 kW).
