Tampering of environmental protection systems on vehicles: Status quo and perspectives
conference paper
Pollutant emissions of road vehicles have significantly reduced thanks to the environmental protection systems (EPS), but tampering with these systems can lead to very low efficiency. In the DIAS project, it was found that there is a substantial market for both light- and heavy-duty vehicles and non-road mobile machinery. The main motives are reduction of costs for repair, consumables and downtime, performance tuning, and increase of the exhaust sound level. Tests with several tampering devices revealed that tampering could deactivate or enable the removal of the EPS, and prevent necessary repair of components without malfunction indication and driver inducement occurring, although several tampering devices and services were not successful. Finally, the testing program enabled the definition of the necessary countermeasures to detect and prevent tampering with these systems. (C) 2023 The Authors. Published by ELSEVIER B.V.
