Beschreibung
Zusammenfassung:	The invention relates to a device (10) for purging the vapours of a fuel stored in a tank (30) of a combustion motor vehicle (1), comprising a control module (130) configured in particular to determine the contribution of the convection of the gas stream to the temperature of said gas stream on the basis of a received gas stream temperature measurement and a received internal pump temperature measurement, in order to determine the contribution of the conduction of the stream to the temperature of the gas stream on the basis of the mass flow rate of the stream, a received temperature of the gas stream and a received internal temperature measurement of the pump, in order to estimate the temperature of the gas stream circulating in a purge circuit (120) on the basis of the determined contributions of adiabatic compression, convection and conduction, so as to calculate the concentration of fuel vapours in the stream on the basis of the estimated temperature.
