Cummins K38 engine is designed to reduce engine operating and maintenance costs while maximizing productivity.

• PT Fuel System – uses the time-tested and proven PT fuel system for high performance and ease of maintenance. PT injectors are built to handle high pressures for optimum combustion. 
• Fillet-Hardened Crankshaft – smaller bolt circle and rolled threads for strength and durability
• Cummins Prelub System – Distributes and pressurizes oil in the engine before cranking can occur, and is proven to greatly extend life-to-rebuild.
• Galley-cooled pistons – reduced piston crown temperatures by as much as 100°F (38°C) for enhanced durability, reduced piston ring wear and 30% longer cylinder life.
