Volvo Penta IPS900 IMO III is a perfectly matched package, powered by the in-line 6-cylinder D13, a 12.8-liter, common-rail diesel and a twin-entry turbo. Working together with a perfectly matched IPS3 pod, twin counter-rotating propellers and the Electronic Vessel Control system, this package offers excellent maneuverability, long action range and low emissions. It´s designed to cope with high back pressure and high-sulfur fuel – up to 1,000 ppm. The SCR (Selective Catalytic Reduction) exhaust aftertreatment system is tailored for a perfect fit. The SCR unit, also a silencer, reduces noise by 35-40 dBA. Volvo Penta has been able to fulfil IMO III exhaust emission targets while maintaining the same low fuel consumption. And thanks to SCR, the engine power output remains unaffected.
