Abstract
An improved catalytic converter and gas purification method for the exhaust gases of an automotive engine is disclosed, the converter including a plurality of honeycomb type catalyst carrier elements, annular spacer members and cushioning rings mounted in compressed sandwich fashion within a cylindrical casing section so that the only rigid connection is between the ends of the assembled sandwich and the casing, the length of the catalyst carrier elements being such that the gases flowing through the passages of each element when the engine is at fast idle will contact the catalyst deposited thereon substantially throughout before changing from its initial turbulent condition to a fully developed laminar condition and the length of the spaces between elements being such as to insure that the flow entering each element is turbulent.
