How does paraffinic diesel affect particulate emissions from diesel engines?

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.
