Upgrading the fuel injection components of marine engines improves engine availability, prolongs component lifetime, ensures engines support future technology upgrades and secures future availability of spare parts. It also reduces the total hydrocarbon (THC) emissions, guaranteeing compliance with the IMO’s MARPOL Annex VI NOx emission limits.
The Wärtsilä Fuel injection equipment upgrade for Wärtsilä 20 and Wärtsilä 20DF engines is a complete package for IMO Tier I and Tier II certified main and auxiliary engines that enables them to benefit from the latest-generation Wärtsilä fuel injection technology.

At 10% engine load when operating in diesel mode, the Wärtsilä Fuel injection equipment upgrade for Wärtsilä 20 and Wärtsilä 20DF engines can reduce THC emissions by up to 40–50%.
Technical info
The upgrade replaces the previous-generation injection pump and injection valve, which are gradually being phased out of Wärtsilä’s spare parts portfolio. The upgrade can be performed as part of the engine’s next scheduled overhaul.
Benefits
Improved engine availability and reduced OPEX
Wärtsilä’s latest-generation fuel injection technology improves engine availability and, for Wärtsilä 20DF engines, can prolong the lifetime of the injection nozzle thanks to a new oil-cooled solution. The new design also reduces the cost of spare parts.
Reduced THC emissions
The upgrade reduces THC emissions across the full load range. For example, at 10% engine load when operating in diesel mode THC emissions can be reduced by up to 40–50%.
Supports future engine upgrades
With the latest fuel injection technology in place, the engine supports future upgrades and long-term spare part availability is secured.
Application
The upgrade is suitable for IMO Tier 1 and Tier 2 certified auxiliary and main engine applications.
