Concern for the environment is one of Volvo Penta's core values, and we are constantly developing our products in order to reduce emissions. Volvo Penta naturally takes a positive view of the introduction of renewable fuels ("biofuels") that can help to reduce the impact of diesel engines on the environment in the future.
Furthermore, the use of biofuels in the future may lead to a situation where the production of fuels is more sustainable than today. One of the recently introduced biofuels is RME ("biodiesel"), which is produced from rapeseed oil and methanol. Today, biodiesel is the most common alternative to diesel. According to the EU's EN 590 standard for diesel fuel, it is currently permissible to blend up to 5 % biodiesel into normal diesel. Accordingly, biodiesel might already be present in the diesel used in the marine sector.
Volvo Penta recommends its customers to operate Volvo Penta's diesel engines only on diesel fuel that conforms to EU standard EN590.
Volvo Penta's diesel engines can be operated on diesel fuel with a higher blend of biodiesel than 5 %- in other words, a higher proportion than stipulated in the EU standard EN590. If such a fuel is used, the engine's emission levels may increase slightly. The engine will also need more frequent service intervals to avoid excessive wear and shorter lifetime.
