Cheat-free emissions measurement

Our Remote Sensing Technology identifies the cheaters and keeps our roads clean.

There is only one way to measure exhaust emissions correctly; on the road with unprepared vehicles driven by everyday motorists. This is already the reality in many countries, for instance in many U.S. states. Thanks to these and similar measurements by scientists and Opus Inspection, the problems with Volkswagen and Audi diesel engines were discovered before the scandal broke.

In late 2014, Opus Inspection found that nitrogen oxide emissions from two-liter diesel Volkswagen and Audi engines on the roads were significantly above regulations, but also above the emissions of similar vehicles.

On September 30 2015, the New York Times published an article about how the use of remote sensing on the roads rather than laboratory testing can be an efficient tool for measuring real emissions from polluting vehicles.

How remote sensing works
The technology has been used for 20 years and the principle is simple. An emission analyzer at the roadside measures the emissions from vehicles passing by and takes a photo of the license plate. The information is transferred to an analysis system. Vehicles with abnormal emissions are identified and directed to undergo emission control. The collected data also shows how well the official emission figures correspond with reality. Read more about remote sensing here.

Should be used for approval
The best way to minimize the possibilities for cheating and to get results that are as fair as possible is to add remote sensing tests on the road to the approval tests in the laboratory environment. Abnormal results will then send a warning to the authorities to carry out further investigations and tests.
