Turbocharger maintenance – what does it mean and why does it matter?

A properly maintained turbocharger improves the fuel efficiency of the engine. Fuel saved means less emissions, which is good for your decarbonisation efforts.

Turbocharger maintenance can be performed at the same time as engine maintenance, or it can be performed separately.

When you choose a qualified service such as Wärtsilä’s, you can be sure that your turbocharger will continue to perform in an optimal way.

Maintain your turbocharger regularly and you can:

  • Improve the efficiency of your engine. This will save fuel and cut harmful emissions.
  • Extend the lifetime of your engine and its components.
  • Contribute to the decarbonisation efforts in the maritime industry.

A well-maintained turbocharger ensures optimal performance:

Wärtsilä’s maintenance services are available also as a long-term maintenance solution which covers all types of equipment. When you choose such a solution from Wärtsilä, it can include turbocharger maintenance: you won’t have to order it separately from a different service provider.

How to keep turbochargers in great condition between overhauls

Clean the turbochargers regularly! Removing the build-up of deposits on the turbine and compressor sides of turbochargers will extend the interval between overhauls. Clean turbochargers are essential for engine performance, and you can achieve the following benefits:

  • Lower risk of unexpected downtime
  • Longer interval between turbocharger overhauls
  • Lower maintenance costs

How to improve engine performance with turbocharger upgrades

The purpose of the turbocharger is to boost engine performance. Maintaining the turbocharger in peak condition with services makes sense, and there are additional improvements to be gained. For example:

Wärtsilä Turbocharger component upgrade will improve the turbocharger’s performance as well as your engine’s performance.

Wärtsilä 50DF turbocharger performance upgrade improves the engine’s performance in gas mode operation because it increases the wastegate margin by around 10 %.

Wärtsilä 46 performance upgrade is a comprehensive, tailored package that boosts the overall engine performance and can achieve the following:

  • Fuel savings of up to 3%
  • NOX emission reductions to comply with emission limits
  • More flexibility for engine operation

Extending the lifetime of the turbocharger

Other upgrade solutions that help improve turbocharger lifetime include the following:
Turbocharger Safety package reduces the risk of downtime because it monitors the turbochargers for critical faults. Early detection helps prevent damage. In addition, the package can achieve the following:

  • Lower risk of unplanned installation downtime
  • Lower risk of human injury

The Wärtsilä Turbo standby cleaner washes the turbocharger turbine when the engine is not running. It helps keep your turbocharger and engine in peak condition. Ideal for cruise vessels, ferries, and power plants operating in environmentally sensitive areas.
