X92

The largest and most powerful two-stroke engine in the portfolio

X92 was developed to provide the best possible propulsion efficiency for modern large and ultra large container vessels due to the optimal selected cylinder power, shaft speed and stroke to bore ratio.

Available in 6 to 12 cylinder configuration, it covers a power range from 24,420 to 77,400kW at 70 to 80rpm.


OPERATIONAL FEATURES

The X92 engine is equipped with the latest state of art development on common rail technology, which results lower fuel consumption across the entire operating range, especially at low and part loads. Intelligent Combustion Control (ICC) system enables further fuel savings by automatic balancing of each cylinder load. Different engine tunings (Standard, Delta, Delta By-Pass and Low Load) are available in order to meet specific customer requirements. The engine is fully compliant with IMO Tier III NOx emission levels when equipped with an SCR catalyst system. Alternatively, an engine internal exhaust gas recirculation (EGR) is being developed and can be available on request. The introduction of the EEDI index also puts an emphasis on CO2 emissions and total vessel efficiency. The internal engine efficiency of X92 and the possibility to apply a Waste Heat Recovery System makes it easy for shipyards to meet these new requirements.

TOTAL COST OF OWNERSHIP

The X92 engine is designed for high reliability and for long periods of maintenance-free operation. It also allows extended Time Between Overhaul (TBO) 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 may be even further extended, thus minimising maintenance costs and maximising the revenue-earning capability of the vessel.

DF-READY OPTION

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.
