METHOD OF ESTIMATING QUANTITY OF N2O PRODUCED ON AMMONIA OXIDATION CATALYST AND EXHAUST GAS PURIFICATION SYSTEM FOR INTERNAL COMBUSTION ENGINE |
摘要 |
<p>An object of the invention is to estimate the quantity of N 2 O produced in an ammonia oxidation catalyst in a case where the ammonia oxidation catalyst is provided in an exhaust passage of an internal combustion engine. In a case where an ammonia oxidation catalyst 14 having the function of oxidizing ammonia is provided in an exhaust passage 6 of an internal combustion engine 1, the quantity of N 2 O produced in the ammonia oxidation catalyst 14 is estimated based on the difference between a measurement value of an upstream NOx sensor 17 provided in the exhaust passage 6 upstream of the ammonia oxidation catalyst 14 and a measurement value of a downstream NOx sensor 18 provided in the exhaust passage downstream of the ammonia oxidation catalyst 14.</p> |
