The shop test for the first domestically produced W9X82 engine was successfully completed.

W9X82The 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.
