SULFUR COMPONENT DETECTION APPARATUS |
摘要 |
<p>The present detector for detecting sulfur components (4) comprises a storage portion (10) for storing SO x and NO x in the exhaust gas passing through an exhaust passage, in which the more an amount of stored SO x increases, the more an amount of stored NO x decreases, and which does not release SO x but release NO x at a set temperature, and a temperature sensor (20), estimates the amount of stored SO x on the basis of a relationship between, after the storage portion becomes the set temperature by heating, a heating pattern of the storage portion and temperature change of the storage portion measured by the temperature sensor, and detects an integrated amount of SO x passing through the exhaust passage during a given period or an value on the basis of the integrated amount.</p> |
