Abstract
A flame arrestor is disclosed for use with an intake of an internal combustion engine, comprising a cylindrical housing defining an inlet and an outlet and a plurality of honeycombed passageways extending between the inlet and the outlet, wherein each of the plurality of honeycombed passageways has a predetermined length and a predetermined small cross-section substantially smaller than the predetermined length. The cylindrical housing is welded within a mounting bracket adapted for receipt in the intake of the internal combustion engine. The flame arrestor is particularly beneficial for use in a boosted engine in that cooling effectiveness and manufacturability are enhanced by the use of the honeycombed structure.
