Manifold reactor

Abstract

In a manifold reactor for an internal combustion engine, the reactor including an inner core and an outer core of elongated cylindrical form, the inner core having open, opposite ends and being concentrically placed within the outer core in spaced relation from the walls of the outer core both in the radial direction and in the axial direction; exhaust gas intake pipes extending from engine cylinders through the walls of the outer and inner cores so as to open within the inner core; and at least one exhaust-gas-discharge pipe, having one end open to an annular space defined between the wall of the outer core and the wall of the inner core, the inner core is split in the axial direction into at least two cylindrical parts which are slidingly connected to each other in air-tight relation, each part being independently secured by welding to the inner surface of the cylindrical wall of the outer core by means of supporting members. The supporting members may be formed from individual bands or by contours in the wall of the outer core. The bands, when utilized, have a central portion secured to the inner core by weld beads and preferably have cut-out areas in the sides adjoining the ends of the weld beads for avoiding thermal stress concentration at these locations.
