<p>The exhaust system of an an internal combustion engine includes a duct having an input end coupled to the engine for passing and processing the exhaust gases and fumes emitted by the engine such that the duct functions as an anti-explosion and fire arrester device. The duct includes a reenforced filter structure (3) securely and firmly mounted within and across the duct opening. The filter structure (3) is coated with a noble metal to enhance oxidation of the gases and fumes passing through the duct. An insulator layer (303) is attached about and along the outer surface of the duct and a jacket (305) for carrying a coolant is mounted - above and about the insulator layer. The insulator layer (303) isolates the coolant from the duct to ensure that the temperature on the external side of the jacket is less than a predetermined value. Simultaneously, the insulator layer isolates the duct from the coolant to enable the temperature within the duct to have a sufficiently high value to sustain oxidation of the gases and fumes.</p> |
