European diesel heavy-duty OBD (On-Board-Diagnostics) |
|
Everyone has noticed the small orange engine icon on the dashboard of his car that is lit ON when starting the engine. This is the OBD symbol showing the vehicle is ready to diagnose any failures that would increase the exhaust emissions of the vehicle up to an unacceptable level.
In Japan, Europe and the USA, the heavy-duty diesel vehicles will also be soon subject to similar "OBD" requirements. It will become mandatory to diagnose malfunctions of the emission control system, but also to record all the parameters that are necessary for a prompt remedy and to be able to communicate this information to third parties. These "OBD" requirements will most probably be worldwide harmonized in the early 2010's.
In the rule making process, the existence of standards for structuring and communicating the information in case of malfunction has a great importance.
These rules are technical rules, which only describe the level of equipment of the engine system and of the vehicle. Today, the other rules that specify when and how the OBD information is used for periodic inspection or road-side checks are mostly left to national initiatives.
