Cummins Introduces K38-M Tier 2 Engine

Cummins Inc. has upgraded the popular KTA38-M0 to meet Tier 2 emissions levels. The new K38-M Tier 2 fills a gap in the market for durable, reliable power designed for use in areas covered under U.S. EPA Tier 2 and EU Stage IIIA emissions regulations. The K38-M Tier 2 is designed for demanding, high-hour, high-load markets such as offshore supply, inland waterways transportation, tugs and towing—applications where the current KTA38-M0 has already proven successful. The 38 liter, V-12 engine shares most hardware with its predecessor; by using a footprint, mount, ratings and optional equipment similar to the existing product, vessel installation has been simplified. Emissions compliance is achieved by minor modifications in air handling and fueling, adjustments to timing and the addition of low temperature aftercooling. The engine also features the proven Cummins PT fuel system enhanced by CENTRY electronic governing, making it one of the few high horsepower Tier 2 certified engines with a mechanically controlled fuel system. In addition to reduced emissions, the K38-M Tier 2 offers several other benefits. Improved air handling and fuel system optimization provide for similar fuel consumption reduced smoke compared to the Tier 1 product. Plus, CENTRY electronic controls and protective shielding provide for safer, more responsive operation. The K38-M Tier 2 will be manufactured by Cummins Inc. on the same production line as the current KTA38-M0. The engine will initially be offered at 850 hp (634 kW) @ 1800 rpm for continuous duty marine applications. The K38-M Tier 2 is covered by a comprehensive global one year warranty valid at authorized Cummins service outlets worldwide. In addition, it is backed by Cummins industry-leading Mobile QuickServe program. Cummins QuickServe offers factory-certified technicians the most sophisticated diagnostic and repair tools in the industry and the largest international parts and service network of any engine manufacturer.
