What can this upgrade do for you?

  • Greater efficiency:  The 3F upgrade delivers Up to Up to 2% points improved fuel usage means savings for you.
  • Lower THC emissions: The new 3F technology delivers a smaller environmental footprint by helping you comply with your country’s THC-emission regulations (such as the future requirements of the 44th BImSchV in Germany).

  • Convenient upgrade: This simple upgrade can be applied at your site during a minor overhaul or at INNIO’s Overhaul Center as part of a major overhaul.
  • Greater runtime (optional): If your engine runs on pipeline gas or treated biogas, you can opt for a special, expanded-scope overhaul at one of INNIO’s repair shops.
  • Future-proof fuel flexibility: The “Ready for Hydrogen” option facilitates your move from conventional fuels today to H2 operation tomorrow, once H2becomes more readily available.

How we get you there?

A key feature of the Type 3F engine is a new four-valve cylinder head and optimized camshaft for better gas exchange. Paired with a new power unit that delivers better combustion, the upgrade results in significantly increased fuel efficiency and lower hydrocarbon-emissions (THC).

Typical engine upgrade scope:

  • Camshaft and cylinder head exchange
  • New pistons and liner
  • Cylinder individual knock control for improved combustion control
  • Turbocharger and gas inlet (TecJet^1) modification, depending on engine version and application
  • Crankcase ventilation system upgrade, if applicable– OEM documentation update

The upgrade is applicable to all Type 3 C-& D-version (50 Hz) engines with a corresponding F-version engine released according to the new unit product program (for instance, D05 versions can be upgraded to F05)
