An internal combustion engine, in particular a stationary gas engine, includes a combustion chamber to which a propellant can be fed from a first propellant source via a combustion chamber pipe, and a pre-combustion chamber to which a flushing gas can be fed via a flushing gas pipe. A flushing gas mixer, in which a propellant to be fed via a propellant pipe from the first propellant source or from a second propellant source, and a synthesis gas to be fed via a synthesis gas pipe, can be mixed is provided. A mixer outlet opens into the flushing gas pipe, and the synthesis gas can be generated by a reformer to which a fuel can be fed from a fuel source via a reformer feed pipe. The reformer outlet of the reformer opens into the synthesis gas pipe, and a cooling device for cooling the synthesis gas is provided.
