Division 2.4.1.2 Discrete-mode NRSC

United Kingdom

The specific emissions e _gas [g/kWh] are calculated by means of equation (7-64):

e_{gas} = \frac{\sum_{i = 1}^{N_{mode}} (q_{m gas i} \times {WF}_{i})}{\sum_{i = 1}^{N_{mode}} (P_{i} \times {WF}_{i})}

(7-64)

where:

q_m _gas, _i

mean emission mass flow rate for the mode i [g/h]

F1P _i

engine power for the mode i [kW] calculated by adding to the measured power P _meas [kW] the power required to drive auxiliaries P _AUX [kW] determined in accordance with equation (6-8) of Annex VI ( P _i = P _meas + P _AUX )

WF_i

weighting factor for the mode i [-]

F2N _mode

number of modes in applicable discrete-mode NRSC
