Benefits & Features
Ultra Lean Burn Technology (ULB)
ULB technology uses an advanced control system, a better turbo match, improved air and fuel mixing, and a more sophisticated combustion recipe to provide: - 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 - Lean air/fuel mixture provides best available emissions and fuel efficiency for engines of this bore size
Advanced Digital Engine Management
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.
