Features

  • Emissions

    Meets U.S. EPA Spark Ignited Stationary NSPS Emissions for 2010 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.
