‘Measuring at the pipe’ provides insight into actual emissions from mobile equipment

Within the Clean and Emission-Free Construction (SEB) knowledge and innovation program, large-scale efforts are being made to accurately determine the emissions of mobile equipment. TNO plays an important role in the ‘Meten aan de pijp’ (Measuring at the pipe) project by transferring knowledge about NOx monitoring to measurement parties, including Fleets-Online. This means that actual emissions, for example of NOx and nitrogen, are continuously monitored using sensors and then validated.

Thanks to an extensive set of sensors on a Komatsu PC290 excavator—and soon on other machines as well—data is collected on fuel consumption, AdBlue, exhaust temperature, and more. This data can be used to compare the calculated emissions (according to the AUB method) with the actual measured emissions. The insights help the construction sector make more conscious choices in the use of equipment and work towards a uniform and accurate measurement method for emissions from mobile machinery.
