Mining Engines


When you depend upon your equipment to move mountains, you can count on Cummins K50 engines to deliver legendary reliability and durability even in the toughest mining applications every day.  With ratings from 1600 – 2000 hp (1194 – 1492 kW) both the industry-leading K2000E – and the K50 engines are ideal for every mining application from electric-drive and mechanical-drive haul trucks and loaders to high duty-cycle excavators and shovels with proven performance and mechanical simplicity of Cummins PT® fuel system.  Cummins K50 and K2000E engines are designed to reduce engine operating and maintenance costs while maximizing productivity.

The K2000E applies robust CENTRY electronic controls and other improvements to the proven K50 engine platform to create a V16 engine reliable, durable and smart enough for the toughest mining applications. In hauling equipment for example, CENTURY controls work with the GE Statex I, II or III Advanced Electric Drive Systems to optimize machine efficiency and fuel savings.

Other features include standard Prelub Systems and CENSE™, an available electronic monitoring package for increased uptime, which keep Cummins K Series engines ahead of the rest for the best life cycle value.

Additional ratings may be available.  Check with your Cummins distributor.

  • 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. 
  • Turbochargers – Custom-built for K Series engines and are available in single-stage or two-stage configurations to meet any application’s requirement.
