At the Volvo Penta press conference during Intermat 2015, attended by IM, the latest additions to its engine lineup were announced, namely new five and eight litre off-road diesel engines. Developed in coordination with the Volvo Group, “these robust, reliable D5 and D8 engines feature a newly designed platform.” Displacement has been increased compared to previous versions, and the new engines offer improved engine block stiffness, as well as higher torque at low speed. But despite a larger displacement, fuel consumption is reduced by as much as 2.5%.

The new engines are available to meet Stage II/Tier 2, Stage IIIA/Tier 3 equivalent and Tier 4 Final/Stage IV emissions standards — “meaning that, no matter where a manufacturer exports its products, Volvo Penta has an engine to match the market’s emission regulations.” All of Volvo Penta’s engines, regardless of emission stage, share a common footprint, with components like the turbocharger located in the same place on all models — making design and installation easier for OEMs.

Ideal for a host of off-road applications including mining, Volvo Penta diesel off-road engines are optimised “to be the most efficient, most cost-effective units possible for OEMs and end users.” The company states that this is why Volvo Penta’s chosen Tier 4 Final/Stage IV solution uses only selective catalytic reduction (SCR) technology, rather than a diesel particulate filter (DPF) or diesel oxidation catalyst (DOC), to reduce emissions. SCR-only technology simplifies installation for OEMs and makes maintenance easier for end users.
