In the USA they flash the exhaust fumes

Measure emissions by infrared? Everyday life in the USA for years. The device manufacturer claims that the technology is good for uncovering scandals like those at VW at an early stage. There is skepticism among German experts.
E.They are two inconspicuous green boxes that stand across from the roadside and target every passing car: speed, acceleration, exhaust emissions, license plates.
The driver does not notice the measurements, but the authorities do: After assigning the pollutant emissions to the respective series, they should be able to quickly sound the alarm if certain models are often conspicuous and then measure more precisely.
The “Remote Sensing” idea from the American company Opus Inspection sounds like a wonder box, but at second glance it makes sense. According to the company, the measuring devices, which send an infrared beam through the exhaust gas and thus determine emissions – for example nitrogen oxides – have been in use in several states in the USA for years.
The boxes are the better investigators?
In view of the VW scandal over falsified emission values, one question arises: Will the exhaust gas flashers be able to detect manipulations more quickly in the future? The manufacturer of the boxes claims: yes. As early as March, based on evaluations of the measurement results, scientists warned of increased nitrogen oxide emissions in diesel vehicles from VW and Audi that have been driving on US roads since 2009.

As a cheaper alternative to the common so-called full hybrid drive, the mild hybrid has been the talk of the town lately. The cheaper 48-volt mild hybrid technology v…on Schaeffler and Continental are to go into series production at a European car manufacturer next year. The two suppliers have already demonstrated it in the "Gasoline Technology Car" (GTC), a converted Ford Focus. The standard consumption of the GTC fell by 17 percent compared to the comparable conventional version of the Ford – to 4.1 l / 100 km and just below 95 grams of CO2 per kilometer.

In Germany, too, there are devices for determining “Real Driving Emissions” (RDE), i.e. pollutant emissions under real driving conditions. In this country, measurement technology is used that works much more precisely than that of the Americans, but cannot be used across the board.
The so-called PEMS (Portable Emissions Measurement System) are housed in the trunk and measure the exhaust gases directly at the exhaust. Because the device is in the car, the technicians can assign the emission values to the car status – for example acceleration or cold start, when vehicles usually emit more.
Entire model series can be checked
The pollutant emissions in real traffic currently have no influence on the type approval, even if the EU is planning to introduce this. Today, before being registered, cars are tested in accordance with the NEDC – the new European driving cycle – under laboratory conditions, with the much-discussed discrepancies between theory and practice.

Many manufacturers wait with the market launch until there is more Zapf…pillars exist, including BMW. On the other hand, there is no need for refueling facilities when there are no cars on the road. A classic chicken and egg problem. Nonetheless, the industry plans to expand the pathetic infrastructure.
The advantage that the Americans promise with their system: instead of just type approval or random checks, entire model series could be checked in everyday traffic. If there are any abnormalities, the authorities can measure more precisely with the PEMS.
This is the only way to determine the emissions in a court-proof manner, warns the international traffic advisor Axel Friedrich, former head of department at the Federal Environment Agency. Using the exhaust gas speed camera alone is no longer appropriate.
The EU is under pressure
In the USA, however, the system could be useful because there are so-called "high emitters", ie cars that have extremely high emissions due to a defect. Perhaps they could be discovered with the system. In Germany, on the other hand, the maintenance behavior of a car owner is significantly better, and the area-wide use of exhaust gas flashers makes less sense.
Upon request, experts from the various German expert organizations did not want to comment on the possibilities of extensive emission measurements using the exhaust gas flashers.
These cars are the most environmentally friendly

The Federal Motor Transport Authority (Kraftfahrt-Bundesamt) also only refers to the applicable EU standards, which stipulate that testing is carried out according to the NEDC. From 2017, it is to be replaced by the WLTP consumption cycle, which is more closely aligned with real driving behavior, but which is also determined under laboratory conditions.
Even if the exhaust gas flashers may not make it into the inventory of German authorities: Against the background of the current manipulation at Volkswagen, the pressure is on the EU to continue to drive forward the determination of pollutant emissions under real driving conditions.
Traffic advisor Friedrich says: “We have to put the entire system to the test. There has to be a fresh start in terms of emission measurements and control of regulations. ”Sp-x
