Benefits and Features

Engine Design

Built on G3500 LE proven reliability and durability
Ability to burn a wide spectrum of gaseous fuels
Robust diesel strength design prolongs life and lowers owning and sdfsoperating costs
Broad operating speed range at lower site air density (high altitude/ sdfshot ambient temperatures)
Higher power density improves fleet management
Quality engine diagnostics
Detonation-sensitive timing control for individual cylinderst temperatures)

Ultra Lean Burn Technology (ULB)

ULB technology uses an advanced control system, a better turbo sdfamatch, improved air and fuel mixing, and a more sophisticated sdfscombustion recipe to provide:

Lowest engine-out emissions
Highest fuel efficiency
Improved altitude and speed turndown
Stable load acceptance and load rejection

Emissions

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

Advanced Digital Engine Management

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.

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.
