Volvo Penta launched its first Stage V-compliant engine for mobile gensets, the D16, in March 2019. By adding the D8 and D13 engines into the mix, Volvo Penta has built a range that features a variety of solutions for customers.
The D8 is a completely new addition to the Volvo Penta genset family; the design is based on proven and mature technology concepts already existing today across the Volvo Group. As with the other Stage V engines, the D8 and D13 additions have been developed with ease of installation, operation and maintenance in mind. Lower maintenance requirements and significantly lower fuel consumption (compared to Stage IIIA) combine to deliver improved total cost of ownership. Volvo Penta has also improved the user environment by lowering the noise output.
Volvo Penta’s Stage V-compliant D8 genset engine is a premium dual speed engine, switchable between 1,500 rpm (50 Hz) and 1,800 rpm (60 Hz) and delivering up to 218 kWm at prime power. It is available in three power nodes: 150, 200 and 250 kVA at 1,500 rpm (50 Hz) at prime power.
Similar to the D8, the D13 engine is also a dual speed engine. Switchable between 1,500 rpm (50 Hz) and 1,800 rpm (60 Hz), it delivers up to 345 kWm at prime power and is also available in three power nodes: 300, 350 and 400 kVA at 1,500 rpm (50 Hz) at prime power.
For both the D8 and D13 genset engines, Volvo Penta selected a low complexity design to maximize robustness and reliability. This was made possible due to high efficiency of the Exhaust Aftertreatment System (EATS), in which the engine and aftertreatment system work seamlessly together. The D8 solution is a two-box system designed for installation flexibility. The D13 solution is a one-box system designed for compact installation. Both engines feature optimized passive regeneration strategies, meaning that active regeneration is kept to a minimum.
