With the increasing importance of alternative drive concepts, advanced, renewable fuels are also moving more into the focus of defossilized mobility. Paraffinic fuels in accordance with DIN EN 15940 - such as HVO (Hydrotreated Vegetable Oil) - offer a promising option for reducing emissions, particularly in road-based heavy goods transport, where diesel engines continue to play a central role.

But how does the emission behavior change when using such fuels? This scientific overview summarizes key findings on particle mass (PM) and particle number (PN) - both before and after exhaust gas aftertreatment. The results show that HVO can lead to a significant reduction in certain emissions - with accompanying effects in the area of particle composition, which should be examined more closely.
