Advantages of Caterpillar CG170-20 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.
