A fuel system for an internal combustion engine ( 12 ) operated with fuel gas includes an evaporator ( 1 ) in which the liquid fuel gas is transformed by the addition of heat into a gaseous state. The evaporator ( 1 ) has a first heating device ( 13 ) configured to transmit a portion of the waste heat of the internal combustion engine ( 12 ) to the fuel gas in the evaporator ( 1 ). The evaporator ( 1 ) has a second heating device, by means of which the fuel gas in the evaporator ( 1 ) can be heated regardless of the condition of the internal combustion engine ( 12 ). The second heating device ( 14 ) can include an electrical heating element, e.g., a PTC heating element. |
