Overview
The line of G3500B engines brings versatility, uptime, and low operating cost to your gas compression operation. They deliver the lowest engine-out emissions in the industry without sacrificing performance.Ideal applications for G3500B engines include gas lift, gas gathering, and wellhead gas compression. Cat G3508B gas engine. Ratings: 514 bkW (690 bhp) @ 1400 rpm are NSPS site compliant capable.
Benefits & Features
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 and some non-attainment areas- 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
