YANMAR Marine International has introduced its innovative Selective Catalytic Reduction (SCR) system, designed to significantly cut NOx emissions from commercial vessels with engines exceeding 130 kW in Emission Control Areas (ECAs). This launch underscores YANMAR’s dedication to advancing sustainable and eco-friendly propulsion technologies.
YANMAR’s SCR system meets the International Maritime Organization’s (IMO) Tier III emission standards which apply to marine diesel engines operating in ECAs, with the system providing a 60-90% reduction of NOx, depending on loading conditions and temperature.
The system can also be fitted to larger leisure vessels (larger than 24 metres) for those seeking to be more sustainable, such as a J Class sailing yacht that was recently fitted with the YANMAR SCR system. This system is not intended for use in the USA.
The advanced emissions control system, paired with the unique common rail technology used in YANMAR’s combustion engines, uses a number of sensors to accurately
