At next week’s UK Seawork 2012 commercial marine exhibition, Scania will be unveiling its new V8 marine engine. Based on the truck engine introduced last year with a 130 mm bore, it displaces 16.4 liters compared to the previous model of 16 liters with 127 mm bore.

Scania is aiming the engine at the commercial market of workboats, ferries, and patrolboats and incorporates many features for that purpose. The fuel system is Scania’s own PDE high pressure fuel injection system with electronically triggered unit injectors. This system was chosen in favour of Scania’s more sophisticated Common Rail XPI system to enhance reliability, durability and greater tolerance to marine fuel conditions that are “less than perfect”.

A centrifugal oil cleaner and twin replaceable fuel filters contribute to the 500 hours oil change interval specified for the engine.

The new engine meets the latest exhaust emission regulations of US Tier 2, EU Stage IIIA and IMO II and will have the ability to meet future regulations, with additional changes. Electronic control of the engine is by a Scania EMS system which with plug and play, fully integrates via a CANbus with navigation and propulsion control systems. Monitoring of engine parameters is automatic and alarm levels can be preset to give warning of any malfunctions: this data also be monitored ashore using a communication suite.

The engine is offered in a number of power outputs to suit workboat and patrol boat ratings ranging between 550 to 1,000 metric hp (405 to 736 kW) in a speed band of 1,800 to 2,300 rpm
