Hence I was wondering whether there is any other way to identify the car model without depending on the comercial name variable (cn). I have seen that the data set also provides other variables names version(ve) and variant(va). Could these ones be of any help?
I’ve realised that in the table 3.42 (TIER 3 - page. 61) there's no FC for EURO later than Euro 4, but the same table shows the emission factors for NOx, CO & PM for the Euro 4 and later.
What factor should I use to calculate Euro 5 and 6 fuel consumption? It means I need to use the same FC for Euro 4, 5 & 6? If I use the same FC for the different EURO, it means the emissions of CO2 are the same for these technologies.
Moreover, I would like to know the FC for Euro 4 & 5 of Two-Stroke and four-stroke mopeds >50 cm3 and the FC for motorcycles >50cm3 Euro 4.
