Wärtsilä’s 34DF Engines Get US EPA Certification

The U.S. Environmental Protection Agency (EPA) awarded Tier III emissions compliance certification to Wärtsilä’s 34DF dual-fuel engine family for 2017, the first Category 3 Tier III certificates issued to any manufacturer.

The certification confirms that the Wärtsilä 34DF engine is fully compliant with the EPA’s emission standards for engines in gas mode operation with a displacement per cylinder of greater than 30 liters. The engines are required to be equipped with a continuous nitrogen oxide (NO_x) measuring and monitoring system for verifying emissions compliancy inside NO_x Emission Control Areas (NECA). When sailing outside NECAs, the 34DF engine can be operated with conventional marine diesel fuels if required.

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