(HELSINKI, Finland) — The technology group Wartsila has been awarded model year 2017 certification of emissions compliance from the United States Environmental Protection Agency (EPA) for its Wartsila 34DF dual-fuel engine family. The EPA Tier 3 certification and the corresponding EIAPP certificate were both issued in March. The Tier 3 certification of conformity covers the Wartsila 34DF engines manufactured from the date of issue until the end of 2017.
These are the first Category 3 Tier 3 certificates issued by the EPA to any manufacturer. Category 3 relates to engines with a displacement per cylinder of greater than 30 liters.
The certification verifies that the Wartsila 34DF engine is fully compliant with the EPA Tier 3 emission standards in gas mode operation. As required by the EPA Tier 3 standard, the engine is equipped with a continuous nitrogen oxide (NOx) measuring and monitoring system for verifying emissions compliancy inside NOx Emission Control Areas (NECA). When sailing outside NECAs, the fuel-flexible 34DF engine can be operated with conventional marine diesel fuels if required.
The 34DF engine features advanced dual-fuel technology and high efficiency, and its success is evidenced with more than 300 engines delivered globally. For marine applications, it is manufactured in configurations from six to 16 cylinders covering a power range of 2,880-8,000 kW. The 34DF's fuel flexibility means that the engine can be optimized for constant speed generating sets, as well as variable speed mechanical drives for main engine applications.
