Internal combustion engine-reformer installation
A method of operating an internal combustion engine-reformer installation having an internal combustion engine and a reformer, includes predetermining at least one parameter of the internal combustion engine, calculating a desired amount of fuel for the reformer on the basis of the at least one parameter, feeding the desired amount of fuel to the reformer, reforming fuel to give a synthesis gas in the reformer, and feeding the synthesis gas to the internal combustion engine. A synthesis gas pressure of the synthesis gas downstream of the reformer is measured, and the synthesis gas pressure is taken into consideration when calculating the desired amount of fuel.
