摘要： PROBLEM TO BE SOLVED: To easily perform regeneration from poisoning of a catalytic converter.
SOLUTION: When a main passage 3 is not closed by a flow passage switching valve 5, when a poisoning quantity predetermined condition correlated to a poisoning quantity of a bypass catalytic converter 8 is realized, the flow passage switching valve 5 is temporarily closed so that exhaust gas flows to a bypass passage 7. Thus, since the exhaust gas flows to the bypass passage 7 side in response to the poisoning of the bypass catalytic converter 8, the poisoned bypass catalytic converter 8 can be regenerated.
