Overview

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. The Cat G3516J gas engines are rated at 1029 bkW (1380 bhp) @ 1400 rpm and 1119 bkW (1500 bhp) @ 1400 rpm as well as NSPS site compliant capable with customer-provided aftertreatment.

Features at a Glance

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.
