Benefits and Features

Engine Design

- Proven reliability and durability - Ability to burn a wide spectrum of gaseous fuels - Robust diesel strength design prolongs life and lowers owning and operating costs - Broad operating speed range

Emissions

Meets U.S. EPA Spark Ignited Stationary NSPS Emissions for 2010 with customer provided aftertreatment.

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.

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.

Ease of Operation

8" HMI Display
- Commonality across gas compression platform
- Color touchscreen
- Set up without Cat ET/laptop

Enhanced Controls
- Multi-rating software for customer horsepower flexibility
- Updated engine performance maps to increase engine stability during load changes and improved fuel tolerance and fluctuation capability
- Maintains updated software maps for improved startability and load accuracy
- Maintains direct NOx control feedback which optimizes engine control strategy

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.
