Abstract

PURPOSE: To prevent detrimental components of exhaust gas produced at low temperature time from discharging into the atmosphere by providing a catalytic unit having activating function at low temperature at the exhaust tube of an internal combustion engine.
CONSTITUTION: The exhaust tube 2 of an internal combustion engine 1 is branched into a conduit 5 having a low temperature CO oxidizing catalyst 8 prepared by mixing components such as platinum, rhodium, palladium, etc. and a conduit 6 having the conventional oxidizing catalyst 7 exhibiting activating function at approx. 1,000°C. A changeover vlave 4 switched by a signal from an exhaust gas temperature detector 3 is installed at the branching portion of the tube 2. Thus, the conduit 5 communicates with the tube 2 at low temperature of the engine to thereby effectively purify the detrimental components via the catalyst 8. The exhaust gas is purified via the catalyst 7 at higher than predetermined temperature.
