ABSTRACT:
A method and apparatus are provided for supplying liquid gas as fuel to an internal combustion engine. From the liquid gas stream that is supplied to at least one liquid gas injection valve of the internal combustion engine, a portion is branched off and expanded. The liquid gas stream supplied to the internal combustion engine is cooled with coldness that results during the expansion, thus ensuring that the liquid gas stream supplied to the liquid gas injection valve is at least substantially liquid. The expanded liquid gas is supplied in a vaporous state to the internal combustion engine.
