Abstract:
The abnormality diagnosis system  1, 1′, 1 ″ of an ammonia detection device  46, 71  comprises: an air-fuel ratio detection device  41, 72  arranged in the exhaust passage  22  at the downstream side of the catalyst  20 ; an air-fuel ratio control part  51  configured to control an air-fuel ratio of exhaust gas; and an abnormality judgment part  52  configured to judge abnormality of the ammonia detection device. The air-fuel ratio control part performs rich control making the air-fuel ratio of the inflowing exhaust gas richer than a stoichiometric air-fuel ratio. The abnormality judgment part judges that the ammonia detection device is abnormal if, after start of the rich control, an output value of the ammonia detection device does not rise to a reference value before the air-fuel ratio detected by the air-fuel ratio detection device falls to a rich judged air-fuel ratio richer than a stoichiometric air-fuel ratio.

Claim (Index 2):
The abnormality diagnosis system of an ammonia detection device according to  claim 1 , wherein the abnormality judgment part is configured to judge that an output of the ammonia detection device is falling if, after the start of the rich control, the output value of the ammonia detection device does not rise to the reference value until a predetermined time elapses from when the air-fuel ratio detected by the air-fuel ratio detection device falls to the rich judged air-fuel ratio.
