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:- Lower environmental impact- Higher return on investment- Lower operating costs- Higher work force efficiency
Emissions
- Capable of meeting U.S. EPA Spark Ignited StationaryNSPS emissions for 2010 and some non-attainmentareas- Lean air/fuel mixture provides best available emissionsand fuel efficiency for engines of this bore size
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.
Testing
Every engine is full-load tested to ensure proper engineperformance.
