Wärtsilä (ship hangar location) recently stated that its Wartsila 34DF dual fuel engine has passed the annual certification of the US Environmental Protection Agency (EPA) Emissions Compliance 2017 New Product.
     The EPA Tier III certification and the corresponding International Engine Air Pollution Prevention (EIAPP) certificate were issued in March 2017. The Tier III certification will cover the Wartsila 34DF engine manufactured from the end of 2017.
     The EPA Tier III certification and the corresponding International Air Pollution Prevention (EIAPP) certificate are the first Class 3 Tier III certificates issued by the US Environmental Protection Agency to any manufacturer. The Class 3 certificate covers engines with a single cylinder displacement greater than 30 liters.
     This certification demonstrates that the Wartsila 34DF engine is fully compliant with the EPA Tier III emission standard in the gas-fired mode. According to EPA Tier III standards, the engine is equipped with a continuous measurement and monitoring of nitrogen oxides (purchasing supply) system to ensure emission compliance in the NOx emission control zone (NECA). When sailing outside the NOx emission control zone, the 34DF engine with flexible fuel burn can operate on less diesel diesel as required.
     As a marine engine, the 34DF dual fuel engine includes a 6-16 cylinder engine covering a power range of 2,880 kW to 8,000 kW. Based on the Wartsila 32 diesel engine (purchased from the product library) launched in the mid-1990s, the flexibility of the Wartsila 34DF dual-fuel engine to burn fuel means that the engine can optimize the group of constant-speed generators (purchasing supply) and as Variable speed mechanical transmission for the main engine (purchasing supply of the product library). To date, Wärtsilä has delivered more than 300 34DF dual fuel engines to the world.
