Features

  • Quantum System Electronics - High-speed Electronic Control Module (ECM) with a self-cooling mount is isolated from detrimental vibration loading. A field-proven, fully-sealed wiring harness with fail-safe connectors integrates the ECM with the engine sensors for optimized engine performance, monitoring and protection.  Quantum system technology is ideal for tough mining applications that demand continuous uptime carrying hundreds of tons capacity.
  • High-Pressure Injection (HPI) Fuel System - Provides a high-peak injection pressure for optimum combustion for low emissions and better fuel economy.  HPI fuel injection provides a “soft” injection start for lower combustion noise.  Other benefits include excellent cold-starting characteristics and improved transient response at all engine speeds.
  • Extra-Wide Gear Train - Quieter, longer-lasting and capable of handling high loads with ease.
  • Single-Stage Turbocharger from Cummins Turbo Technologies - Lower intake air temperatures provide increased air density, resulting in more power and lower emissions from less fuel.
  • Full-Authority Electronics - Programmable electronic controls optimize combustion at all altitudes and conditions.
  • Two-Stage Cummins Oil Filter - Combination full-flow and bypass oil filter reduces maintenance costs as it extends service intervals.
  • Precision-Honed Cylinder Liners - Precise liner machining with superior metal technology creates exceptional surface smoothness and durability.
  • Power Cylinder Package - Proven single-piece ferrous cast ductile iron pistons for maximum durability and reliability. This advanced design also uses nitrided liners and cast-iron top rings to handle injection pressures with exceptional durability.
  • High-Durability Camshaft - Microfinishing makes it last twice as long as previous designs. Improved contact between the crosshead and rocker lever reduces wear and improves durability.
  • Prelub™ System - Distributes oil to rifles and friction surfaces and builds oil pressure before cranking can occur.  A pressure switch assures proper oil pressure in the main rifle to reduce the risk of starting the engine without oil in the sump or filters.  Prelub is a standard option on all mining engines due to proven success in extending engine life-to-rebuild.
  • Premium Fan Drive – Incorporates large matched and sealed bearings, improved oil seals, and an improved idler system.  The fan drives have fixed fan centers with tensioning provided by a manually adjusted and maintenance free idler.  The fan drive is available with or without an electronically controlled oil-actuated fan clutch.
