Abstract
Abstract A method and apparatus for continuously producing a charge gas mixture for the operation of an internal combustion engine in which liquid hydrocarbons are partially oxidized into a combustible gas mixture within a reactor under insufficiency of air, whereby the liquid hydrocarbons are admixed at a predetermined ratio below the stoichiometric ratio to a first partial air quantity flow which is preheated prior to entry into the reactor, in which additionally the hot gas mixture formed in the reactor is cooled off while giving off at least a considerable part of its heat to the first partial air quantity flow, is mixed with a second partial air quantity flow at least at a stoichiometric approximately constant mixture ratio and is fed to the internal combustion engine; the second partial air quantity flow itself or a quantity flow containing the second partial air quantity flow as a predominant component is continuously measured as regards quantity and the supply of the liquid hydrocarbons is metered as a function of the measurement of the magnitude of this quantity flow while the quantity flow of the gas mixture formed by the reactor is throttled in relatively hot condition.
