CG170-12 Gas Generator Set

From natural gas-fueled combined heat and power (CHP) systems and emergency power for facilities, to renewable biogas energy to support the local grid, or electricity generated from coal mine gases, Caterpillar has a wide range of reliable gas power solutions.


High Efficiency, Lower Operating Costs

  • Miller cycle timing with combustion chamber and spark plug improvement help on saving up to 15% fuel gas per year
  • CG170 (non-miller) is optimized for Island-Mode capability
  • Gearbox helps limit wear and tear on engine components, lowering operating costs and increasing availability

Low installation, Building and Operating Costs

  • Extended maintenance intervals up to 64,000 Oh
  • Low fuel consumption due to improved combustion chamber and pre-chamber spark-plugs
  • Flexible fields of application also with fluctuating gas qualities due to Total Electronic Management (TEM)
  • Optimized oil management

Optimized Lubrication Consumption

  • Consumes up to 1900 liter less lube oil per year than comparable models<li>
  • Longer lubricant change and oil change intervals<li>
