Wartsila tests 2-stroke dual-fuel gas engine technology

Wartsila successfully tests new 2-stroke dual-fuel gas engine technology to comply with IMO Tier III emission limits. The on-going tests show that the Wartsila 2-stroke gas engine performance is in compliance with the upcoming IMO Tier III NOx emission limits, thereby setting a new benchmark for low-speed engines running on gas.

Wartsila, the marine industry’s leading solutions provider, has successfully tested its new low-speed gas engine technology in trials conducted at the company’s facilities in Trieste, Italy. The tests were carried out on September 19 in conjunction with Wartsila’s Licensees Conference in Trieste. Wartsila successfully demonstrated that the engine performance fully complies with the upcoming IMO Tier III nitrogen oxide (NOx) limits, thereby setting a new benchmark for low-speed engines running on gas.

The new RTX5 2-stroke test engine is part of Wartsila’s 2-stroke dual-fuel gas engine technology development programme. This is an important part of the company’s strategy to lower emissions, increase efficiency and to develop its low-speed engine portfolio to include dual-fuel gas engines alongside its medium-speed dual-fuel engines.

“The decision to initiate this project was announced in February 2011, just seven months ago. The fact that we have already conducted a successful test shows that our gas engine technology is at the forefront of meeting the future needs of shipping, a future that stipulates more stringent environmental regulation. This further highlights Wartsila’s leading in-house know-how, professional approach and overall competence in this field,” says Lars Anderson, Vice President, Wartsila Ship Power Merchant.

The tests with the RTX5 engine will continue during the autumn and winter of this year, and into 2012. More details about the engine technology and its performance will be announced upon completion of the programme.

The running of the test during the company’s Licensees Conference is significant in that the company’s low-speed engines are produced by specialised engine manufacturing companies under license. The licensees market, manufacture and sell the engines under agreed conditions. Wartsila has established a world-wide network of 19 licensees for manufacturing 2-stroke engines. These are located mainly in Asia (Japan, Korea, China, Vietnam).
