K38
Cummins
The Cummins K38 engine is a cornerstone of heavy-duty power, engineered to deliver unmatched reliability and performance in the world's toughest environments. Part of the legendary K-Series, this 38-liter V12 powerhouse is built on a foundation of mechanical simplicity and robust design to maximize productivity and uptime while minimizing operating and maintenance costs for critical industries worldwide.
The following table summarizes the core specifications of the versatile K38 engine platform:
The K38 is the prime mover of choice for high-value capital equipment where continuous operation is essential.
Mining Equipment: The engine's legendary durability makes it ideal for electric drive haul trucks, large wheel loaders, hydraulic excavators, and shovels, where it delivers the power and reliability needed for 24/7 productivity.
Marine Propulsion & Auxiliary Power: A proven performer in tough commercial marine environments, the K38 is certified for main propulsion and auxiliary generator sets on commercial vessels, workboats, and super yachts.
Oil & Gas and Industrial: The engine reliably powers critical equipment such as high-pressure fracturing pumps, mud pumps, large industrial air compressors, and stationary generator sets.
The K38's reputation for long life and low cost of ownership is built on several key, field-proven technologies.
Proven PT® Fuel System: Utilizing the time-tested Cummins PT mechanical fuel system, the K38 ensures high performance, optimum combustion, and exceptional ease of maintenance. The system can be operated with full-authority Cummins CENTRY™ electronic controls for precise fueling, performance monitoring, and automatic timing adjustment.
Durability-Enhancing Engine Architecture: Critical components are engineered for extreme longevity. The fillet-hardened crankshaft provides superior strength. Gallery-cooled pistons reduce crown temperatures by up to 100°F (38°C), significantly extending cylinder life and reducing ring wear.
Advanced Systems for Reliability and Uptime: The Cummins Prelub System pressurizes oil throughout the engine before startup, dramatically reducing wear and extending the engine's life-to-rebuild. The design also features replaceable wet cylinder liners for easier serviceability and lower rebuild costs.
Optimized Air Handling: Equipped with custom-built turbochargers available in single-stage or two-stage configurations, the K38 can be precisely matched to application requirements for optimal performance and efficiency.
