Benefits and Features

  • Built on G3500 LE proven reliability and durability
  • Ability to burn a wide spectrum of gaseous fuels
  • Robust diesel strength design prolongs life and lowers owning and sdfsoperating costs
  • Broad operating speed range at lower site air density (high altitude/ sdfshot ambient temperatures)
  • Higher power density improves fleet management
  • Quality engine diagnostics
  • Detonation-sensitive timing control for individual cylinderst temperatures)

ULB technology uses an advanced control system, a better turbo sdfamatch, improved air and fuel mixing, and a more sophisticated sdfscombustion recipe to provide:

  • Lowest engine-out emissions
  • Highest fuel efficiency
  • Improved altitude and speed turndown
  • Stable load acceptance and load rejection

  • Meets U.S. EPA Spark Ignited Stationary NSPS emissions for 2010 and some non-attainment areas
  • Lean air/fuel mixture provides best available emissions and fuel efficiency for engines of this bore size

ADEM A3 engine management system integrates speed control, air/fuel ratio control, and ignition/detonation controls into a complete engine management system. ADEM A3 has improved: user interface, display system, shutdown controls, and system diagnostics.

Large variety of factory-installed engine attachments reduces packaging time

Every engine is full-load tested to ensure proper engine performance
