Division Formula 2

The least squares method shall be used for the fitting of the curves. To do that, at least the temperature measurement data of the first 30 minutes after engine cut-off are not to be considered because of the untypical behaviour of the coolant temperature after switching off the coolant system.

Using Formula 1, the engine temperature at specific parking time conditions ( $T_{\mathrm{eng}}^{\mathrm{ti}}$ ) should be calculated and given in Table 1.
