Mixture of CO and H₂ is produced by partial combustion of a hydrocarbon fuel, such as CH₄, with substantially pure O₂ in a cylinder of an internal combustions engine. The fuel and the O₂ are charged at a pressure of 50-100 p. s. i. g. in sufficient amount to fill the cylinder, the ratio of O₂: C being within the range 1.0:1.4 The charge is then compressed to 1/3-1/5 the volume of the cylinder and ignited, the products of the partial combustion being withdrawn at a pressure of at least 50 p. s. i. g. The gaseous hydrocarbon fuel may be preheated before being introduced in the cylinder to above 1,000° F., the fuel and the O₂ then being separately charged into the combustion zone.
