The Wärtsilä 46 Performance upgrade is a tailored performance upgrade package that boosts engine performance by optimising the combustion process and tuning the engine to the most frequently used operating range. The Wärtsilä 46 Performance upgrade make use of modern higher efficiency turbochargers, and when combined with Miller inlet valve timing and engine tuning the engine’s performance is maximised with regards to fuel oil consumption and generated emissions. This will lower operational costs and aid in complying with tightening emission limits, all the while increasing operational efficiency.
Performance optimization can be sought for in areas such as full load or low load optimization, emission reduction, or optimization with regards to SFOC and emission reduction in general. The scope of the package is determined case by case according to customer requirements. Engine documentation update (i.e. EIAPP amendment), in case needed, is part of Wärtsilä’s delivery scope.
