Abstract
A manifold type thermal reactor, for use in an internal combustion engine mounted on cars or other vehicles to collect exhaust gas from a plurality of engine cylinders into a reaction chamber is described. The chamber includes an external shell and an internal shell. The thermal reactor includes an external tubular pipe connecting at least one of the cylinders with the reactor and an inlet pipe connecting the tubular pipe with one of the openings formed in the internal shell. The angle between the axis of the inlet pipe and the axis of the internal shell is more than 0.degree. and less than 90.degree.. A gas-tight clearance is provided to allow sliding of the inlet pipe relative to a circular opening in the internal shell in the direction of the axis of the inlet pipe. A crescent-shaped clearance is formed between the external shell, having a cylindrical surface around a center line which is parallel with and apart a certain distance from the center line of the inlet pipe, and the external peripheral surface of the inlet pipe, and the external peripheral surface of the inlet pipe. The gas-tight clearance along with the crescent-shaped clearance will smoothly absorb the difference of the thermal expansion between the external shell and the internal shell by displacement of relative shell and the internal shell by displacement of relative position between the inlet pipe and the internal shell and by that between the inlet pipe and the external shell.
