Features at a Glance
- 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.
