Abstract
During the starting, a) the temperature (T) of the engine and the pressure (P) of the fuel delivered by said pressurizing means are monitored, b) if T is below a predetermined threshold temperature (Ts), an engine starting mode is established in which the engine is started with fuel at high pressure as soon as the pressure (P) becomes higher than a predetermined threshold pressure (Ps1), and c) an engine starting mode is established where the engine is started using fuel at low pressure if T>Ts.
