Documents & Spec Sheets
Features & Benefits
Emissions
Meets U.S. EPA Spark Ignited Stationary NSPS Emissions for 2010/11 with the use of an oxidation catalyst
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
Includes engine mounted thermostats, compress oil cooler connections, jacket water and lube oil heater connections.
Advanced Digital Engine Management
ADEM4 engine management system integrates speed control, air/fuel ratio control, and ignition/detonation controls into a complete engine management system. ADEM4 has improved: user interface, display system, shutdown controls, and system diagnostics.
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.https://gerp.cat.com
Product Support Offered Through Global Cat Dealer
A number of upgrade kits are available for Cat® G3600 engines. For customers looking to enhance the performance while continuing to meet emissions requirements of their gas compression fleet, consider a Gen 2 Kit and/or the Closed Crankcase Ventilation (CCV) System retrofit.
