# Commission Delegated Regulation (EU) 2017/654 of 19 December 2016 supplementing Regulation (EU) 2016/1628 of the European Parliament and of the Council with regard to technical and general requirements relating to emission limits and type-approval for internal combustion engines for non-road mobile machinery, Division 2.1.5.1: Tabulated values

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

Applying some simplifications (assumption on the λ value and on intake air conditions as shown in Table 7.1) to the equations set out in point 2.1.5.2, the resulting values for u gas are given in Table 7.1.
Table 7.1
Raw exhaust gas u and component densities (for emission concentration expressed in ppm)
Depending on fuel
At λ = 2, dry air, 273 K, 101,3 kPa
u accurate within 0,2 % for mass composition of: C = 66 – 76 %; H = 22 – 25 %; N = 0 – 12 %.
NMHC on the basis of CH2,93 (for total HC the u gas coefficient of CH4 shall be used).
u accurate within 0,2 % for mass composition of: C3 = 70 – 90 %; C4 = 10 – 30 %.
