Exhaust gas purification device for internal combustion engine |
| abstract |
An exhaust gas purification device has an SCR catalyst (44), a urea water injection valve (55) for supplying urea water to the upstream of the SCR catalyst (44), a downstream-side air fuel ratio sensor (an oxygen concentration sensor provided with a diffusion resistive layer) (66) provided in the downstream of the SCR catalyst. When a predetermined condition is satisfied, the exhaust gas purification device stops the injection of the urea water from the urea water injection valve and acquires the output value from the downstream-side air fuel ratio sensor under the state as a first output value. The exhaust gas purification device acquires the output value from the downstream-side air fuel ratio sensor at the time when the urea water is injected from the urea water injection valve, as a second output value. The device acquires the concentration of ammonia flowing out from the SCR catalyst on the basis of the difference (ΔAF) between the first output value and the second output value. |
