Wärtsilä X35 Engine Passes Factory Acceptance Tests
Wärtsilä’s new electronically controlled low speed engine, the Wärtsilä X35, has successfully passed its Factory Acceptance Tests (FAT), which took place in February at the 3.MAJ Engines & Cranes company facilities in Croatia, and the Yuchai Marine Power Co., Ltd. (YCMP) factory in China.
The measured parameters included stresses, strains, temperatures and vibrations in the engine structure, running gears and combustion chamber components, together with pressures and temperatures in the engine processes, as well as fuel consumption, exhaust gas emissions and smoke. The tests also confirmed the predicted brake specific fuel consumption (BSFC) of 176 g/kWh, within the usual 5% margin under IMO Tier II conditions.
This was the first six-cylinder Wärtsilä X35 engine to be produced and tested in Europe, the company said. It is the first of four such engines scheduled for manufacturing and testing at 3.MAJ during 2012. 3.MAJ is a long-standing licensee of Wärtsilä, having signed its license agreement in 1954. The second of the tested engines was produced at YCMP, a Wärtsilä licensee since 2009. Like 3.MAJ, YCMP is a single licensee, meaning that they manufacture only Wärtsilä two-stroke engines.
The Wärtsilä X35 is a new Wärtsilä engine that, together with the Wärtsilä X40, will cover the small-bore end of the market. The engines will be used for smaller bulk carriers, product tankers and container feeder vessels, Wärtsilä said.
