Division Formula 4

United Kingdom

NP (T_{eng}^{ti}) = \frac{{CO}_{2} (T_{cold}) - {CO}_{2} (T_{eng}^{ti})}{{CO}_{2} (T_{cold}) - {CO}_{2} (T_{hot})}

Then, the theoretical engine coolant temperature after discharging the EST system for the selected parking time conditions $T_{engmod}^{ti}$ , shall be calculated using Formula 5.
