1. A combustion engine system comprising:

  • a combustion engine having a combustible gas inlet and an exhaust gas outlet;

    a fuel reservoir for containing liquid methanol;

    means for vaporizing said liquid fuel into methanol vapor;

    means for feeding said liquid fuel from said reservoir to said vaporizing means;

    decomposition reactor means including walls defining a flow-through decomposition zone containing a vapor-premeable body of solid, selective methanol decomposition catalyst coated on a high heat capacity support for catalytically decomposing said methanol vapor selectively into a soot free product gas consisting essentially of hydrogen and carbon monoxide at a temperature from 250°

    C. to 650°

    C.;

    means for heating said decomposition reactor to a temperature from 200°

    C. to 650°

    C.;

    means for transferring said vapor to said decomposition reactor means from said vaporizing means;

    carburetor means for mixing an oxygen containing gas with said product gas to form combustion gas consisting of product gas and oxygen;

    means for continuously transferring said combustion gas from said carburetor means to said combustion reactor during operation of the engine; and

    means connecting said exhaust gas outlet to said heating means.
