Wärtsilä 20DF greenhouse gas reduction upgrade

A low crevice technology upgrade will reduce methane slip

Opt for the Wärtsilä 20DF greenhouse gas reduction upgrade and the methane slip will be reduced in the whole range of engine load. This upgrade includes a so-called “low crevice technology” upgrade in addition to software updates. The software upgrade delivers combustion phasing control, which will make the engine operate optimally according to its ambient and operating conditions.

Wärtsilä 34DF greenhouse gas reduction upgrade

A straightforward software upgrade will reduce methane slip

Any vessel powered by Wärtsilä 34DF engines can reduce its GHG emissions with an easy-to-access control software upgrade. The package is called Wärtsilä 34DF greenhouse gas reduction upgrade, and it will reduce unburned total hydrocarbon (THC) emissions because it will reduce the charge air pressure and air-fuel ratio. The upgrade is based on adaptive combustion phasing control, which optimises engine behaviour according to the ambient and operating conditions.

Wärtsilä 50DF greenhouse gas reduction upgrade

Achieve methane slip reduction with an engine upgrade

There are several ways to reduce methane slip from your Wärtsilä 50DF engine. For example:

  • upgrading turbochargers
  • tuning exhaust wastegate
  • updating piston crowns
  • implementing skip firing function for part- or low load operation
  • installing flute pipe or slip pilot injection.

Based on your needs, Wärtsilä can tailor a solution to fit your exact requirements. The result will be a modernised engine which will perform better overall.
