This patent describes the combustion-engine generation of hydrogen and carbon monoxide by the reaction of a hydrocarbon with an oxygen-containing gas. In this process, said reactants are charged into the combustion space of a four-stroke-cycle internal-combustion engine in approximate relative proportions for the formation of hydrogen and carbon monoxide. It is then mixed and compressed and subjected to internal combustion with the generation of mechanical energy. The products of reaction are exhausted from the combustion space. The improvement of the process consists of charging a limited amount of air to the combustion space immediately following the period in which products of reaction are exhausted therefrom and prior to the introduction of the hydrocarbon. The said hydrocarbon is then introduced with a limited amount of relatively pure oxygen to the combustion space into admixture with said air. The sad air thereby effects the cooling of the combustion space prior to the introduction of relatively pure oxygen. The process continues by compressing the mixture of reactants, igniting said mixture to produce products of reaction comprising carbon monoxide and hydrogen containing a predetermined amount of nitrogen and exhausting said products from the combustion space.
