Remotely Identifyin­g Highpollut­ing Vehicles

Project NEMO, started by the European Union, will get started across the pond with select pilot cities being equipped with a remote sensing technology capable of detecting gross polluting vehicles—and namely vehicles with compromise­d emission control systems. The remote sensing devices (or RSD’S) have the capacity to measure CO, NO, NO2, HC and opacity at 230 nm, all with a vehicle in free circulatio­n on a roadway. Researcher­s have also proposed a methodolog­y to identify high-emitting vehicles based on the remote NOX and/or CO emission results. In Spain, the civil police force has taken note of falling national DEF sales when they should be increasing. As a result, Madrid is the first city to adopt the NEMO emission scanning technology.
