Engine Design

- 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

Emissions

Meets U.S. EPA Spark Ignited Stationary NSPSEmissions for 2007/8

Lean Burn Engine Technology

Lean-burn engines operate with large amounts of excessair. The excess air absorbs heat during combustionreducing the combustion temperature and pressure,greatly reducing levels of NOx. Lean-burn design alsoprovides longer component life and excellent fuelconsumption.

Advanced Digital Engine Management

ADEM A3 control system providing integrated ignition,speed governing, protection, and controls, includingdetonation-sensitive variable ignition timing. ADEM A3has improved: user interface, display system, shutdowncontrols, and system diagnostics.

Ease of Operation

Side covers on block allow for inspection of internalcomponents

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.
