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

Emissions

- Meets U.S. EPA Spark Ignited Stationary NSPSemissions for 2010- 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.

Gas Engine Rating Pro

GERP is a PC-based program designed to provide siteperformance capabilities for Cat® natural gas enginesfor the gas compression industry. GERP providesengine data for your site’s altitude, ambient temperature,fuel, engine coolant heat rejection, performance data,installation drawings, spec sheets, and pump curves.
