Stricter control technology for diesel vehicles starts in January 2019.


Currently, emissions inspections involve analyzing the opacity of exhaust gas only; in the near future, it will involve a complete analysis of exhaust gas called the “5 Gas Analysis”.

The 5 gases that will be analyzed are the following:

  • Carbon monoxide (CO)
  • Carbon dioxide (CO2)
  • Unburnt hydrocarbon (HC)
  • Tiny particles that are already being analyzed in current emissions inspections
  • Nitrogen oxide (NOx) which we heard so much about during the VW scandal.

This analysis will involve an inspection of the catalytic converter functions in diesel vehicles, as well as the DPF, a component that allows a portion of HC to escape when it becomes clogged.

Owners of older vehicles, this pertains to you: The new measure will mean that 20% fewer old diesel vehicles will pass inspection, not to mention the fact that driving the streets of Paris is already forbidden since July.

This will be quite an investment for technical centers that will have to pay an average of €25,000 on new equipment.

The goal is quite specific: eliminate the vehicles that cause the most pollution in our country, where 62% of vehicles in circulation are diesel vehicles…


(*It’s worth considering descaling your engine with hydrogen; our process uses the power of a solvent consisting of post-combustion hydrogen, which eliminates calamine from the engine, from the catalytic converter and from the DPF, and, thus, keeps them from getting clogged. A healthy engine is an engine that pollutes less.)
