# 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 2.3.1.2: Full flow dilution system

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

The mass emission shall be calculated by means of equation (7-48):
m PM = m f m sep × m ed 1000
(7-48)
where:
m f is the particulate mass sampled over the cycle [mg]
m sep is the mass of diluted exhaust gas passing the particulate collection filters [kg]
m ed is the mass of diluted exhaust gas over the cycle [kg]
with
m sep = m set – m ssd
(7-49)
Where:
m set mass of double diluted exhaust gas through particulate filter [kg]
m ssd mass of secondary dilution air [kg]
