Engine Design

  • 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)

Ultra Lean Burn Technology (ULB)

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

Emissions

  • 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
