G3516J Gas Engine
THE RUNDOWN
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.
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.
