Wärtsilä says that the first example of its new electronically controlled X35 low-speed engine series has been successfully started at the Chinese premises of Yuchai Marine Power (YCMP).

Wärtsilä says that the X35 is a completely new design that, together with the Wärtsilä X40, will cover the small-bore end of the market, a segment where Wärtsilä has not been present for a number of years. The X-generation engine series was launched in May 2011, as the RT-flex35 and RT-flex40, and the names subsequently changed in line with Wärtsilä’s product portfolio. It employs common-rail RT-flex technology, and features an extra long stroke to achieve improved fuel economy and increased operational flexibility. According to the company, the rating field allows optimum propeller requirements to be satisfied.

The first Wärtsilä X35 engine was produced at YCMP's new 48,000 m2 factory, which has been a Wärtsilä low speed engine licensee since October 2009 and is located in Zhuhai on the southern estuary of the Zhujiang Delta in Guangdong Province.

The running engine was introduced to an audience of invited guests during a ceremony, at which YCMP signed the first supply contracts for the new Wärtsilä X40 engines. At the ceremony, Martin Wernli, president Wärtsilä Switzerland and vice president product centre two-stroke said: “The production of the new Wärtsilä X35 engine at these high-quality new manufacturing facilities is indeed a landmark occasion. We believe that this series of electronically controlled low-speed, two-stroke engines is absolutely in line with the current and future needs of the marine sector. In particular it meets the requirements set by coastal and river transportation vessels. China is one of the key markets for this engine, and the fact that it is manufactured by our licensee YCMP is indicative of our commitment to further strengthening our presence in the Chinese market."

"The smooth assembly and running of this first of the new type engines at this brand new factory is the result of the excellent co-operation between Wärtsilä and YCMP. YCMP has secured substantial orders for this new engine type and is committed to being a dedicated manufacturer of it," says Mr Jiang Shihong, president and CEO of YCMP.

The start-up of the first Wärtsilä X35 engine at YCMP was attended by representatives from Guangdong Province, the Zhuhai city government, the General Consuls of Finland and Switzerland, senior Wärtsilä executives, and major customers in China.
