The shop test for the first domestically produced W9X82 engine was successfully completed at the end of April and was shipped to JMU Kure shipyard on 19th June 2015.
Wärtsilä X-Generation engines (long stroke) were developed to fulfill the market need of reducing fuel consumption by improving both engine and propeller efficiency. High-performance product like FAST nozzle (fast actuated sacless technology), Pulse Jet cylinder lubrication and others are already adapted to Wärtsilä X-Generation engines as standard equipment.

Depending on growing in size of container vessel, W9X82 engines have received a lot of attention recently from the marine market.

The key benefits compared to products available in the market today are:
- Lower speed and optimized stroke-to-bore ratio offering best engine and propulsion efficiency
- Optimized Total Cost of Ownership
- Lowest manufacturing costs with high reliability as first priority
- Optimized installation at shipyards with beneficial ancillary power requirements
- Reduced CO2, SOx and NOx emissions, offering yards excellent possibilities to fulfill the EEDI definition
- Fully compliant with the NOx emissions regulation of Annex IV of the MARPOL 1973/78 convention for Tier II and/or Tier III
- R1/R1+ concept offering flexibility for selecting the most effective propulsion system for defined ship applications.
