Description
Tyre wear emissions are a growing concern due to their impact on the environment and tyre performance. Particles are generated from the friction between tyres and roads, as well as from tyre heating.
Since tyre wear produces particles in a wide size range, from a few nanometres to several micrometres, a measuring device with a broad range is needed.
Measurement method
The Dekati ELPI®+ is ideal for measuring the particle number concentration and size distribution of tyre wear emissions. With a frequency of 10 Hz, it can capture rapid changes in these variables in real time. The High-Resolution version can measure up to 500 size classes.
The ELPI®+ uses a cascade impactor for size classification, allowing the collected particle fractions to be analyzed using chemical or electron microscopy methods (SEM/TEM). This helps identify which size fractions are more likely to originate from tyre wear and which come from road wear.
