I'm just applying for the Crit'Air certificates for my Motorhome and scooter.
I've just scanned the V5's and sized them, but on reading the details for my 2009 Hymer B660 3-litre 5000kg Mercedes (sold to me as Euro-4 compliant), I note that some of the emissions values are listed in g/kWh rather than g/km.
On the V5, the legend states (eg):
"NOx (g/km or g/kWh) 3.004"
Note it doesn't specify which measure is listed.
I don't think there's a valid conversion from g/kWh directly to g/km but does it matter? Will the scrutineers of the application understand the situation unprompted? The values are orders of magnitude different - Euro 4 NOx is 0.25 g/km vs. my specified 3.004 g/kWh so I hope that the dimensions / units will be apparent?
On researching, I see that emissions values for Heavy Trucks are calculated differently to Light Trucks / Cars - The latter are measured on a vehicle dynamometer, the former on an engine dynamometer. So perhaps the fact that I'm registering a heavy truck will mean they look at the appropriate values?
Anyone had any experience yet?
