# Commission Implementing Decision (EU) 2017/785 of 5 May 2017 on the approval of efficient 12 V motor-generators for use in conventional combustion engine powered passenger cars as an innovative technology for reducing CO2 emissions from passenger cars pursuant to Regulation (EC) No 443/2009 of the European Parliament and of the Council (Text with EEA relevance), Division: Formula 8

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

s η MG = ∑ i = 1 4 h i × s η MG i – 2 The standard deviation of the motor generator efficiency ( s η MG ) leads to an error in the CO2 savings ( s C CO 2 ). That error is calculated in accordance with the following Formula 9:
