Building on the KTA38’s reputation hard earned on the U.S. inland rivers Designed to withstand the challenging conditions commercial marine operators often face; this same reliable, durable power is now available for recreational boating applications, including super yachts and yacht support vessels Improved idle stability and reduced noise and vibration are a direct result of the Cummins Modular Common Rail fuel system In-cylinder technology to meet IMO Tier II and EPA Tier 3; Cummins exhaust aftertreatment system, using Selective Catalytic Reduction System (SCR) technology, meets EPA Tier 4 and IMO III. Covered by a comprehensive one year warranty and backed by Cummins global service network Built at Daventry Engine Plant in Daventry, U.K. Features & Benefits Engine Design: Reliable base engine uses common components from the proven K19, K38, and K50 engines. A new steel piston with PVD coating top ring along with nitride coated second ring and high boron liner provides the excellent durability and long life withstanding higher temperatures and meeting the stringent emission norms. No matter the vessel, Cummins will keep you always on. Fuel System: Proven High Pressure Modular Common Rail Fuel System features an increased system pressure and optimized fueling. The pump is designed to give higher fuel pressure throughout the engine speed and load range. Benefits include low noise, low vibration for quiet operation, improved performance, idle stability and low-end torque while still delivering improved fuel economy. Cooling System: Two-pump, two-loop, low temperature aftercooling maximizes efficiency and improves performance.
