New nine litre workboat range from Scania

Developed as part of Scania’s global engine platform, the new engine is built according to the same modular design programme as Scania’s existing 13 and 16 litre units. This means many components are shared across the range, a design benefit which offers considerable operational and maintenance advantages. Between them the three members of Scania’s engine family provide a comprehensive selection of power outputs spanning 220 to 1,000 horsepower.

Designated DI9M, the new nine litre engine is a compact five cylinder in-line turbocharged unit offered in a choice of five propulsion power outputs ranging from 220 to 400 horsepower. As such, the DI9M is particularly well suited to a broad selection of commercial workboat applications. The unit also lends itself as an auxiliary power source suitable for uses as diverse as generator sets, onboard pumps and bow thrusters, with four ratings from 199 to 323 kW available.

The Scania DI9M has a service interval of 500 hours. In terms of maintenance, and in common with Scania’s 13 and 16 litre units, the unit features individual cylinder heads to permit one man servicing, an especially useful benefit in the confined spaces of a marine engine room. The engine is also equipped with Scania’s Saver Ring, which has been designed to reduce wear and extend engine life. Fitted inside the cylinder liner, the Saver Ring removes soot and other residue trapped between the upper piston ring and the piston top.
