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.
A method 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 shortage of air, and in which the liquid hydrocarbons are admixed to a first partial air quantity flow which is preheated prior to entry into the reactor, at a predetermined ratio below the stoichiometric ratio, the hot gas mixture formed in the reactor is cooled off by 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 an at least stoichiometrically approximately constant mixture ratio and is then fed to the internal combustion engine, comprising the steps of continuously measuring a partial air quantity flow representative of the second partial air quantity flow, metering the admixture of the liquid hydrocarbons in dependence on the measured value of said partial quantity flow, and throttling the quantity flow of the gas mixture formed by the reactor in relatively hot conditions.
An apparatus for continuously producing a charge-gas mixture for the operation of an internal combustion engine, comprising means for partially oxidizing liquid hydrocarbons within a reactor means into a combustible gas mixture under shortage of air including preheating means for preheating a first partial air quantity flow prior to entry thereof into the reactor means, means for admixing liquid hydrocarbons to said first partial air quantity flow at a predetermined ratio below the stoichiometric ratio, means for cooling off the hot gas mixture formed in the reactor means by giving off at least a considerable portion of its heat to the first partial air quantity flow, means for mixing the thus-cooled partial air quantity flow at an at least stoichiometrically approximately constant mixture ratio with a second partial air quantity flow, and means for feeding the thus obtained mixture to the internal combustion engine, characterized by measuring means continuously measuring as regards quantity, the second partial air quantity flow, metering means connected to said measuring means for metering the supply of the liquid hydrocarbons as a function of the magnitude of the measured quantity flow, and throttle means for throttling the quantity flow of the gas-mixture formed by the reactor means in relatively hot condition.
