Wärtsilä has announced that its X40 two-stroke engine has successfully passed its Type Approval test (TAT). The testing was carried out in
Zhuhai, China, at Wärtsilä's licensee
Yuchai Marine Power Co. Ltd. (YCMP).
In passing the TAT, the engine is verified as having fulfilled all classification society requirements and will be fully introduced to the market following sea trials, which are currently being undertaken.
According to Wärtsilä, an important feature of the testing was meeting the SOLAS (Safety of Life at Sea) standards. With a single engine powering the propeller, the engine must be capable of continuous operation under all conditions.
The Wärtsilä X40, as well as the Wärtsilä X35 engines, features Wärtsilä's second-generation version of its electronically controlled common rail system with time-controlled fuel injection.
The Wärtsilä Generation X Engines feature a higher stroke to bore ratio, thus achieving lower engine speed and lower brake specific fuel consumption (BSFC). With this technology the fuel injection for each cylinder, as well as the cylinder lubrication, is controlled by a single module to provide fuel efficiency and reliability as well as lower operational costs. The engine also incorporates the state-of-the-art UNIC-flex control system, which is based on Wärtsilä's UNIC (Unified Controls) platform.
"The TAT validation procedure is comprehensive and very demanding and we are delighted to announce that the Wärtsilä X40 engine has passed this milestone with flying colours. The key value adding feature of this engine is that its high level of efficiency lowers the operational costs for owners, operators and charterers. In the current market conditions, this is extremely important," remarked
Martin Wernli, Managing Director, Wärtsilä Switzerland and Vice President, Wärtsilä Ship Power, 2-stroke.
The Wärtsilä X40 and Wärtsilä X35 cover the small-bore end of the market. The engines will be used for smaller bulk carriers, product tankers and container feeder vessels.
