Particle Counting – FAQ
News - 07/12/2022
Switzerland is optimising its method for measuring exhaust emissions and introducing particle counting.
What will change in 2023 during the periodic follow-up inspection?
Until now, only exhaust emissions and smoke opacity were measured during emissions testing of diesel vehicles. Particulate number measurement is now mandatory.
Which vehicles are affected by the new regulations?
The new measure applies to all diesel vehicles fitted with a particulate filter:
• cars: from Euro 5b onwards
• heavy vehicles: from Euro VI.
Does the particle counter replace the exhaust gas analyser? Is the particle counter compulsory?
Emissions testing remains compulsory for older diesel vehicles without a particulate filter (e.g. Euro 4).
However, cantonal motor vehicle authorities and testing centres that wish to continue testing the emissions of diesel vehicles with particulate filters must equip themselves with an additional particulate matter measuring device.
Do I need to replace my exhaust gas analyser?
Existing measuring devices can be upgraded. In our devices, particulate measurement is compatible with the entire range of Capelec gas analysers.
You can also use a ‘stand-alone’ device to avoid the cost of upgrading your existing equipment.
How does the Capelec particle counter work?
Currently, soot measurement is carried out with the accelerator pedal pressed all the way down, which measures the maximum smoke emission.
With the Capelec particle counter, the measurement is taken at idle without having to press the accelerator pedal – a process that is polluting, noisy and stressful for both engines and operators.
Is the Capelec exhaust particle tester easy to use?
It’s very simple to use; the results are displayed in real time via Bluetooth on a laptop, tablet or smartphone, and the PASS/FAIL result is clear.
The process is completed in a matter of seconds.
Why choose Extended DC technology over other options?
The Extended DC principle involves electrically charging the particles by diffusing a high ionic density. The soot particles are drawn in by a flow of clean air via the Venturi effect. This keeps the sensor clean and reduces the need for maintenance.
