Abstract
A variable capacity catalytic converter for control of noxious exhaust emissions from combustion engines consists of a plurality of interchangeable parts or modules each having a male portion and a female portion, which can be assembled in an additive way to provide the capability of producing a range of sizes of catalytic converters having varying volumes of catalyst while utilizing identical sets of components. Depending upon the engine requirements with which the converter is to be used, different numbers of modules can be assembled by stacking. An inward projection on an end cap of each module helps maintain a turbulent flow of gases through the device to produce uniform flow through all of the catalyst beds.
