Features

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>

Greater oil change interval

Lower lube oil consumption leading to greater time interval between lube oil changes

savings on service

Extended maintenance intervals leading to lower service costs
