Abstract
Disclosed are cell-type ignition devices for Otto cycle internal combustion engines, said devices having cylindrical cells with end orifices communicating with the engine combustion chamber. The devices include housing and mounting means for thermally isolating the cell from the cooled engine wall and the ambient atmosphere. Critical ratios for cell dimensions are disclosed. Some embodiments are equipped with supplementary glow or spark ignition means for starting and warm-up. In some embodiments, sleeves or external protubances on the cell wall are employed to regulate ignition timing by controlling heat transfer.
