PROPULSION UPDATE Cummins Expands HP Range, Debuts New K38 Engine fuel inj ection and more efficient com- bustion; • a new cylinder head design for improved engine performance across the operating range; • water-cooled turbochargers; • single point exhaust outlet; • dry exhaust manifold with water- cooled shield; • premium "K" injectors; • ceramic injector link for longer life. Since the K engines debuted in 1974, the "V" engines have been regarded as reliable, durable and fuel-efficient, Mr. Rabe said. The KV series engines are built in Daventry, England, and more than 20,000 are in service worldwide.

The K38 is now available at rat- ings of 1,320 bhp (985 kW) for me- dium continuous duty, and 1,200 bhp (895 kW) or 1,050 bhp (784 kW) for continuous duty applications. Typical duty for the engine is aboard fishing vessels, tugs and barges, crewboats, and ferries. Previously, the 12-cylinder K38 had a top rating of 1,045 bhp. "These new ratings, and the tech- nology that's been applied to bring them to the market, represent much more than just anuprate," saidPaul Rabe, vice president and general manager, Cummins Marine. "Be- cause of its more efficient fuel con- sumption (.331 bsfc at rated speed for 1,200 bhp), the K38 offers a lower annual operating cost. "Other customer benefits include improved durability, higher horse- power and better performance," he added. The engine is expected to be avail- able in early 1995, and the latest version of the K38 provides many end-user advantages. A new Holset turbocharger, low-temperature aftercooler and a new gallery-cooled piston are amongthe major improve- ments to the engine.
