What is the standard Euro ?

The European Commission is at the origin of European emission standards, more commonly called “standards”. Euro HAS". The aim of these standards is to control the rate of polluting emissions from all vehicles, and to reduce it a little more each time. Contrary to what one might think at first glance, carbon dioxide (CO2) is not one of the controlled pollutants since it exists naturally in the atmosphere. Thus, the polluting gases concerned par the norm are hydrocarbons (HC), nitrogen oxides (NOx), carbon monoxide (CO) and microparticles (MP).

The induced constraints par European emission standards mean that all road transport tends towards minimum pollution. That said, they also act as an accelerator of new technologies, which are therefore more efficient.ar consuming less. But this also causes some constraints for motorcyclists, particularly when it comes to driving in the city center. Restricted traffic zones (ZCR) are toughening up with mandatory Crit'air stickers and extending to all major French cities.

What changes with the standard Euro 5+?

In terms of controlling polluting emissions, to tell the truth, not much. It is not a new standard that awaits manufacturers but rather an update of the standard Euro 5. On the other hand, it will introduce new criteria for on-board diagnostic devices, durability tests and sound tests. The idea here is to ensure that polluting emission levels do not exceed the authorized limit both when the motorcycle is new and later.

To do this, the catalyst durability test must no longer be based on a calculation of deterioration, but on taking real data on the road or track. So, Euro 5+ introduces a new phase of OBD II on-board diagnostics with more stringent engine emissions durability testing and additional noise reductions. However, this risks causing problems for certain entry-level systems which today pass the accuracy standard and which mathematical calculations could save.

The OBD II on-board diagnostic tool will no longer be content with checking the correct connection of the sensors and the consistency of the data collected, but will also have to monitor the catalyst, the sensors oxygen or even combustion misfires. A verification frequency is introduced here, with the system now having to carry out an analysis at least every 10% of the time the 2-wheeler is in use (~ every 35 km). This system makes it possible to check for possible anomalies in the exhaust gases. In the event of a malfunction, a warning light will light up on the motorcycle's dashboard. This will significantly reduce the engine torque (degraded mode), which will have the consequence of encouraging the user to go to their dealer or an approved workshop.
