WinGD completes new 2-stroke engine tests

Tests at Yuchai Marine Power have confirmed performance and compliance of the X52-S2.0, while the prototype project validated ease of assembly and maintenance.

“The recent test campaign of this newest X-S engine has confirmed that this series delivers exceptional fuel efficiency and emissions performance,” said WinGD head of Global Testing & Validation, Sotiris Topaloglou.

“The footprint reduction will drive cost efficiencies while the new concept dramatically simplifies engine construction, installation, maintenance and service.”

The successor to the RT-flex50 and RT-flex58, the X-S series is available in 52cm and 62cm bore sizes with confirmed orders already for diesel, LNG and methanol configurations. An ammonia fuel option is also under development.

The company reports that tests have shown a fuel reduction over the equivalent RT-flex engine of around 10k per kWh, a saving of around 4% depending on operating profile.

The type approval tests followed similar successful tests for the larger X62-S2.0 engine at Dalian Marine Diesel in April.

The first order for the X52-S2.0 was received in February 2023 followed by a second order with iSCR, WinGD’s on-engine NOx abatement solution, in July.
