# Commission Regulation (EC) No 692/2008 of 18 July 2008 implementing and amending Regulation (EC) No 715/2007 of the European Parliament and of the Council on type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information (Text with EEA relevance), Division 2.1.3: Transfer functions

Extent: E+W+S+N.I.

The transfer function TF ( p 1,…, p n ) referred to in point 2.1 is set to 1 for the entire range of parameters p i (i = 1,…,n) .
If the transfer function TF ( p 1 ,…, p n ) is amended, this shall be done in a manner which is not detrimental to the environmental impact and the effectiveness of the RDE test procedures. In particular the following condition shall hold:
∫ TF ( p 1,…, pn ) * Q ( p 1,…, pn ) dp = ∫ Q ( p 1,…, pn ) dp
Where:
dp represents the integral over the entire space of the parameters p i (i = 1,…,n)
Q(p 1 ,…, p n ) , is the probability density of an event corresponding to the parameters p i (i = 1,…,n) in real driving.
