      Features at a Glance

      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.
