Division: Formula 12 - Commission Implementing Decision (EU) 2016/362 of 11 March 2016 on the approval of the MAHLE Behr GmbH & Co. KG enthalpy storage tank 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)

where k = 1, 2, …, 5

T₁ = T_cold

T₂ = T_hot

T_{3} = T_{eng}^{t1}

T_{4} = T_{eng}^{t2}

T_{5} = T_{eng}^{t3}

The standard deviation of the CO₂ savings $S_{C_{{CO}_{2}}}$ is to be calculated by means of Formula 13.
