ABSTRACT:
An exhaust gas purification system for internal combustion engine having a thermal reactor interposed in the exhaust passage. The thermal reactor comprises a heat insulated inner shell for defining a reaction chamber therein and a core shell provided in the core shell spaced therefrom for providing a space between the both shells. A pair of exhaust pipes communicating with the exhaust valves of the engine are inserted into the core shell through an opening of the core shell so as to form a confluence and constant swirling of the exhaust gases in the core shell to provide a high temperature zone in the center of the swirling. The opening of the core shell is narrowed for preventing high temperature zone from moving out of the reaction chamber.
