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 lowersowning and operating costs
  • Broad operating speed range at lower site air densities(high altitude/hot ambient temperatures)
  • Higher power density improves fleet management
  • Quality engine diagnostics
  • Detonation-sensitive timing control for individualcylinders

Ultra Lean Burn Technology (ULB)

ULB technology uses an advanced control system, abetter turbo match, improved air and fuel mixing, and amore sophisticated combustion recipe to provide:- Lowest engine-out emissions- Highest fuel efficiency- Improved altitude and speed turndown- Stable load acceptance and load rejection

Advanced Digital Engine Management

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

Full Range of Attachments

Large variety of factory-installed engine attachmentsreduces packaging time.

Quality

Every Cat engine is manufactured to stringent quality standards in order to assure customer satisfaction.
