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.
The delivery of the product contains the following modifications:
RT-flex82T, RT-flex58T-D, RT-flex58T-E, RT-flex82C, X82 and X72 engines
The pilot installation of Wärtsilä Fuel efficiency boost shows around 10~12 ton / day lower fuel consumption than sister vessel in the same route and resulted to 1,195 ton of fuel saving in 9 months.
