# Commission Regulation (EU) 2017/1151 of 1 June 2017 supplementing 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, amending Directive 2007/46/EC of the European Parliament and of the Council, Commission Regulation (EC) No 692/2008 and Commission Regulation (EU) No 1230/2012 and repealing Commission Regulation (EC) No 692/2008 (Text with EEA relevance), Division 3.4.1: Calculation of the correction criterion c


The correction criterion c is the ratio between the absolute value of the electric energy change ΔEREESS,j and the fuel energy and shall be calculated using the following equations:
c=ΔEREESS,jEfuel
where:
cis the correction criterion;
ΔEREESS,jis the electric energy change of all REESSs over period j determined in accordance with paragraph 4.1. of this Appendix, Wh;
jis, in this paragraph, the whole applicable WLTP test cycle;
EFuelis the fuel energy calculated with the following equation:
Efuel = 10 × HV × FCnb × d
where:
Efuelis the energy content of the consumed fuel over the applicable WLTP test cycle, Wh;
HVis the heating value in accordance with Table A6.App2/1, kWh/l;
FCnbis the non-balanced fuel consumption of the Type 1 test, not corrected for the energy balance, determined in accordance with paragraph 6. of Sub-Annex 7, and using the results for criteria emissions and CO2 calculated in Step 2 in Table A7/1, l/100 km;
dis the distance driven over the corresponding applicable WLTP test cycle, km;
10conversion factor to Wh.
