Wärtsilä Fuel efficiency boost

A high efficiency of the main engine is a key factor for the profitable transport of cargo by vessels. An upgrade with the Wärtsilä Fuel efficiency boost enables the fuel costs of two-stroke engines to be reduced considerably while complying with exhaust emission regulations.

A well balanced combination of an increased compression ratio and modified injector nozzles combined with optimized engine tuning parameters allows fuel savings of up to 4% without significantly increasing the NOx emissions.

    Technical info

    The delivery of the product contains the following modifications:

    1. Increase of compression ratio and firing pressure by higher compression shim
    2. Injection nozzle with bigger bore to shorten the injection duration
    3. Optimization of engine tuning parameters 
    Benefits
    • Reduction of fuel consumption by up to 4% depending on engine load, rating and certified NOx emissions
    • Reduction of greenhouse gases
    • NOx levels remain within the Tier II limits
    Application
    • X82
    • RT-flex82T
    • RT-flex58T-D
    • RT-flex58T-E

    Business White Paper: Wärtsilä Fuel Efficiency Boost

    Engine upgrade cuts fuel costs and emissions for charterers

    A simple engine retrofit for two-stroke engines could cut fuel consumption at a time when ship charterers have never been more focused on fuel costs and emissions. After a successful pilot installation, Wärtsilä is now offering the Fuel Efficiency Boost (FEB) upgrade through its comprehensive service network.
