Title:
SULFUR COMPONENT DETECTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2008/088072
Kind Code:
A1
Abstract:
In an internal combustion engine, a metal or a metal compound (10) capable of capturing
a sulfur component contained in an exhaust gas is provided in a flow path of the
exhaust gas. When the amount of the sulfur content captured by the metal or the
metal compound (10) is increased as the lapse of time, a physical property of the
metal or the metal compound (10) which varies with increase in the amount of the
captured sulfur component is measured. Based on the measurement value, the
sulfur component in the gas can be detected.
