Wärtsilä 34DF engine certified for EPA Tier III

The certification, covering engines manufactured this year, is the first for a Category 3 engine, which are defined as those with a displacement per cylinder of more than 30 litres.

The award verifies that the engine is compliant with EPA Tier III emission standards in gas mode. As required by the standard, the engine is equipped with a continuous NOx measuring and monitoring system for verifying emissions compliancy inside NOx emission control areas (NECA).

“It is an honour for the company to be the first to be awarded this important EPA certification,” commented Patrik Wägar, product director, medium bore engines, Wärtsilä Marine Solutions.
