The most compact engine in its class of very low shaft speed engines

The compact design with limited engine width and height makes X52 suitable for slim hull lines and the wide rating field offers optimum propeller speed for different application. Thanks to the engine’s agility, it is the optimum choice for several vessel segments e.g. Handymax tankers and bulk carriers or 1000–1800 TEU feeder container vessels.


WinGD’s well proven electronically-controlled common-rail technology plays a key role in enabling ship owners to reduce fuel costs, mainly through the flexibility of the fuel injection and exhaust valve operations. This flexibility results in lower fuel consumption across the entire operating range, especially at low and part loads. In addition, different engine tunings (Low Load and Delta Bypass) are available in order to meet specific customer requirements. Other advantages of this technology include stable low running speeds, smokeless operation, and improved control of exhaust emissions.  The engines are equipped as standard with Intelligent Combustion Control (ICC) system enabling further fuel savings and balanced working of each cylinder.

The engine is fully compliant with IMO Tier III NOx emission levels when equipped with a SCR catalyst system. Alternatively, an engine internal exhaust gas recirculation (EGR) is being developed and available depending on requirements. The introduction of the EEDI index also puts an emphasis on CO2 emissions and total vessel efficiency. The X52’s internal engine and propulsion efficiencies, and the possibility to apply various Power Take Off (PTO) arrangements for on-board electricity production, make it easy for shipyards to meet these new requirements. Thanks to WinGD’s common-rail technology, the engine produces no visible smoke and remains energy efficient at all loads.  The X52 has also been designed to allow for easy retrofit of the two-stroke Dual-Fuel technology, providing fuel flexibility to owners and operators.


All areas of lifecycle costs have been taken into account for the X52. The selected stroke-to-bore ratio makes the engine compact and has a positive impact on the manufacturing cost. The X52 is designed for exceptional reliability and for long periods of maintenance-free operation. It also allows extended Time Between Overhaul (TBO) of the critical components, to as much as 5 years. The service-friendly design will reduce downtime, maintain vessel operation and cut operating costs. Together with Condition Based Maintenance (CBM) and service agreements, the overhaul interval could be even further extended, thus minimising maintenance costs and maximising the revenue-earning capability of the vessel.


All Generation X engines can be converted to use LNG as fuel. For simplifying the future conversion WinGD has introduced the DF-ready version as an option. The DF-ready engines can be easily converted to dual-fuel, as no major structural components need to be modified. All parts, which are to be replaced at a later conversion, are either typical wear parts or specific X-DF components and systems. DF-ready version is the recommended solution for LNG-ready ships.
