G3508 LE
G3508 Low Emission Gas Compression Engine
DESCRIPTION
The line of G3500 engines brings versatility, uptime, and low operating cost to your gas compression operation. They are equipped with ADEM A3 technology that enables highest performance and safety while maintaining low emissions. Ideal applications for G3500 engines include gas lift, gas gathering, and wellhead gas compression. Cat G3508 gas engine. Ratings: 391-500 bkW (524-670 bhp) @ 1200-1400 rpm are NSPS site compliant capable with customer-provided air-fuel ratio control and aftertreatment or available for non-regulated areas.Emissions
Meets U.S. EPA Spark Ignited Stationary NSPS Emissions for 2007/8
Advanced Digital Engine Management
ADEM A3 control system providing integrated ignition, speed governing, protection, and controls, including detonation-sensitive variable ignition timing. ADEM A3 has improved: user interface, display system, shutdown controls, and system diagnostics.
Lean Burn Engine Technology
Lean-burn engines operate with large amounts of excess air. The excess air absorbs heat during combustion reducing the combustion temperature and pressure, greatly reducing levels of NOx. Lean-burn design also provides longer component life and excellent fuel consumption.
Ease of Operation
Side covers on block allow for inspection of internal components
Full Range of Attachments
Large variety of factory-installed engine attachments reduces packaging time
Testing
Every engine is full-load tested to ensure proper engine performance
Gas Engine Rating Pro
GERP is a web-based program designed to provide site performance capabilities for Cat® natural gas engines for the gas compression industry. GERP provides engine data for your site's altitude, ambient temperature, fuel, engine coolant heat rejection, performance data, installation drawings, spec sheets, and pump curves.
