n this paper, technology to form a high concentration of hydrogen and carbon monoxide, based on partial oxidation of methanol, was investigated for improvement of cold startability of neat methanol S. I. engines. Ignition conditions of a mixture of flammable gas and oxygen, and air dilution ratio necessary to form a flammable mixture were discussed. Test results show that the highest concentration of hydrogen that can be produced at the rich limit of a premixed flame is about 20%. It is essential to maintain the level of hydrogen concentration at 5% or more, and to supply sufficient air to ensure that the oxygen concentration is at least 9% to achieve engine starting.
