Volvo Penta D8 MG is a constant speed, in-line 6-cylinder, 7.7-liter diesel engine using common-rail fuel injection, overhead camshaft, a twin-entry turbo. This contributes to optimized operating economy and high diesel performance, combined with reduced emissions and noise. It’s designed to handle high back pressure and high-sulfur fuel (1,000 ppm). The SCR (Selective Catalytic Reduction) exhaust aftertreatment system is designed to deliver an optimal fit. The SCR unit, which also acts as a silencer, reduces noise by 35-40 dBA. Volvo Penta has met IMO III and Inland Waterway Stage V exhaust emission targets while maintaining low fuel consumption. Thanks to SCR, the engine power output remains unaffected.
