VM’s MR504, MR704, MR706 and MR506 marine engines have now been added to the list of engines tested and approved for the use of HVO EN 15940 ecological fuel. The tests demonstrated that with HVO fuel there is a 20% reduction of PM emissions, 10% reduction of NOx and 2% reduction of CO2 emissions. Furthermore, HVO fuel has no impact on performance or reliability and can be used without requiring modifications to the engine or additional maintenance. 

HVO fuel is an ecological and sustainable synthetic diesel which is produced mainly from renewable sources such as oils and vegetable fats. The hydrogenation process creates a high-quality paraffinic fuel which has a high cetane number (>70) and a pure composition. Its density is around 7% less than diesel making it more stable. Compared to traditional diesel fuel, HVO has a reduced aromatic and sulphur content while the H/C (hydrogen/carbon) ration is slightly higher. Additionally, it is not susceptible to bacterial growth therefore making it ideal for long storage. HVO fuel is particularly suitable for rigid climates where the high cetane number and low gelling point (-32°C) make it ideal for cold starts. It can be blended and used in any proportion with diesel which allows for ease of transition.
