Designed for reliability & easy maintenance, also used for generating set applications
The Wärtsilä 32 was developed in response to a need in the market for a new engine in the 320 mm cylinder bore class and since 1998 more than 1200 of these engines have been sold worldwide.
Based on the latest achievements in combustion technology, it is designed for efficient and easy maintenance in combination with long maintenance-free operating periods. The engine is fully equipped with all essential ancillaries and a thoroughly planned interface to external systems.
The Wärtsilä 32 engine is fully compliant with the IMO Tier II exhaust emissions regulations set out in Annex VI of the MARPOL 73/78 convention.

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.
