This paper investigates methanol combustion behavior with different metals in the combustion chamber wall, and determines means to improve ignitability. The results indicate that among the metals tested iron is the most effective in improving methanol ignition. In IDI engines, ignition is affected more by the metal in the chamber wall than in DI engines, as in the case of combustion systems where more unburnt methanol tends to remain longer. The in-chamber concentration of formaldehyde, an intermediate product of methanol combustion, appears to be an important determinant for methanol ignition. To achieve smooth ignition without misfiring, a specific formaldehyde concentration is necessary immediately prior to methanol injection in the combustion chamber.
