Advantages of Caterpillar CG260-12 Gas GenSet

  • Engine Design : Proven reliability and durability, Ability to burn a wide spectrum of gaseous fuels, Robust diesel strength design prolongs life and lowers owning and operating costs, Broad operating speed range.

  • Advanced Digital Engine Management : ADEM A3 control system providing integrated ignition, speed governing, protection, and controls, including detonation-sensitive variable ignition timing. ADEM A3 has improved: user interface, display system, shutdown controls, and system diagnostics.

  • 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 : Side covers on block allow for inspection of internal components.

  • 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.
