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