Mixtures of gaseous methanol, oxygen, and nitrogen were ignited on a hot surface in an enclosed combustion chamber without convective flow. It has been found from thee measurements of ignition temperature of these mixtures that a transition occurs in the ignition temperature under certain conditions. The same transition was also observed fro the gaseous methanol-iso-octane blends. Further, the intensity of OH emission at ignition was measured near the heated plate. The intensity change of OH emission and the gradient of its rise were different in the high and low-ignition temperature regions. Next, the ignition mechanism of methanol by a hot surface was investigated theoretically. The theoretical result suggested that the transition occurs if the activation energy for the low ignition temperature region is lower than the generally recognized value.
