- Meets U.S. EPA Spark Ignited Stationary NSPS emissions for 2010 - Lean air/fuel mixture provides best available emissions and fuel efficiency for engines of this bore size

ADEM A3 engine management system integrates speed control, air/fuel ratio control, and ignition/detonation controls into a complete engine management system. ADEM A3 has improved: user interface, display system, shutdown controls, and system diagnostics.

Large variety of factory-installed engine attachments reduces packaging time.

Every engine is full-load tested to ensure proper engine performance.

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.

More than 2,200 dealer outlets Cat factory-trained dealer technicians service every aspect of your petroleum engine Cat parts and labor warranty Preventive maintenance agreements available for repairbefore- failure options S•O•SSM program matches your oil and coolant samples against Caterpillar set standards to determine: - Internal engine component condition - Presence of unwanted fluids - Presence of combustion by-products - Site-specific oil change interval

Over 60 years of natural gas engine production Ownership of these manufacturing processes enables Caterpillar to produce high quality, dependable products - Cast engine blocks, heads, cylinder liners, and flywheel housings - Machine critical components - Assemble complete engine
