| titleOfInvention | Exhaust gas purification device for internal combustion engine |
| abstract | (57) Abstract: It is possible to prevent NO X from being released to the atmosphere and to forcibly make an air-fuel mixture rich when releasing absorbed NO X. An air-fuel ratio is detected by a lean sensor. When the duration of the lean state is less than the predetermined time α is, only the first valve 21 to open NO X absorbent decomposer 18 Only the exhaust gas is made to flow into NO X is absorbed in, When the duration of the lean state is equal to or longer than α, the second valve 2 2, also flowing the exhaust gas in the NO X absorbent 27 of the third valve 23 opens. When the duration of the stoichiometric or rich state is less than the predetermined time β, only the first valve 21 is opened to allow the exhaust gas to flow only into the NO X absorption / decomposition agent 18, When the duration of the stoichiometric or rich state is equal to or longer than β, the first valve 21, the second valve 22, the fourth valve 24, the fifth valve 25 By driving the pump 32 with opening the, NO X absorbent 2 The exhaust gas flows from 7 toward the NO x absorption / decomposition agent 18. |
