In designing the engines, consideration was given to their intensive use and to the desirability of easy and simple maintenance. These engines feature individual cylinder heads and wide inspection doors in the block, which makes access to the inside parts of the engine easy, and shortens the service time during maintenance and repair processes.
This series comprises six and eight cylinder in-line engines as well as twelve and sixteen cylinder 60º V-bank engines.

Engine Design - Reliable base engine uses common components from the proven K19, K38 and K50 engines. A new cast-iron, ductile single-piece piston with nitride-coated rings and hardened cylinder liner increases durability and reduces maintenance
Fuel System - Modular Common-Rail Fuel System features a simplified design which provides constant high injection pressure regardless of engine speed or load conditions. Benefits include significantly reduced noise and vibration for quiet operation, better idle stability and improved low-end torque
Cooling System - Single-loop cooling eliminates the need for two keel coolers for reduced installation expense. Engine-mounted titanium plate heat exchanger provides superior durability with minimal maintenance requirements
Exhaust System - Water-cooled exhaust manifold cools engine surface temperatures. Design is a cast single piece construction that eliminates potential exhaust leakage
Air System - Mounted or remote marine grade air cleaner with replaceable element reduces maintenance cost. Water-cooled turbocharger optimized for vessel operating conditions and safety
