Wärtsilä 26

Compact & light unit with low operating costs, also used for generating set applications

The Wärtsilä 26 was developed in response to a need in the market for a new engine in the 260 mm cylinder bore class. The shortest and lowest engine in its class, the Wärtsilä 26 requires minimal space in the engine room.

Wärtsilä works in close co-operation with its customers when conducting field tests and monitoring selected test components. The Wärtsilä 26 has fewer parts, less maintenance requirements, low fuel consumption, reduced emission levels, and has the ability to run reliably on a variety of fuels.

The Wärtsilä 26 engine is fully compliant with the IMO Tier II exhaust emissions regulations set out in Annex VI of the MARPOL 73/78 convention.

    WÄRTSILÄ UNIC

    Wärtsilä engines are delivered with the UNIC embedded engine management system.

    The UNIC system is designed to ensure extended lifetime for large marine diesel and gas engines operating in the toughest of conditions. Special attention has been paid to temperature- and vibration endurance throughout the design, while the highest priority has been given to operational reliability.

    Key features of the UNIC system include the engine safety system, local monitoring, speed control with loadsharing, fuel injection- and timing control, knock detection, alarm signal acquisition, start/stop sequencing, load reduction request, system diagnostics, and a fieldbus interface as applicable for each engine configuration.

    Thanks to the electronic control, the engine can be adapted to different operating conditions. Furthermore, the pre-tested configuration allows the engine or generating set to be made ready for operation with a minimum of commissioning and installation work.
