Division 5.3.2 Specific fuel consumption figures for cold-hot emission balancing factor

The specific fuel consumption figures needed for the cold-hot emission balancing factor shall be calculated from the actual measured values for both, the hotstart and coldstart WHTC test recorded in accordance with paragraph 4.3.3. The calculations shall be performed for both, the hotstart and coldstart WHTC separately as follows:

• SFC_{meas, hot} = Σ FC_{meas, hot} / W_{act, hot}

• SFC_{meas, cold} = Σ FC_{meas, cold} / W_{act, cold}

where:

SFC_{meas, j}

Specific fuel consumption [g/kWh]

Σ FC_{meas, j}

Total fuel consumption over the WHTC [g] determined in accordance with paragraph 5.2 of this Annex

W_{act, j}

Total engine work over the WHTC [kWh] determined in accordance with paragraph 5.1 of this Annex
