摘要： An emission control device stores SOx when the air/fuel ratio of exhaust gas is lean, and releases the stored SOx when the temperature of the emission control device is raised to a desulfurization temperature or higher and the air/fuel ratio of the exhaust gas becomes substantially equal to the stoichiometric air/fuel ratio or rich. The emission control device's temperature is controlled to be within a predetermined temperature range whose lower limit is substantially equal to or higher than the desulfurization temperature, and sulfur is released from the emission control device by controlling the air/fuel ratio of the exhaust gas to be substantially equal to the stoichiometric air/fuel ratio or rich when the temperature of the emission control device is within the predetermined temperature range. In the method, the temperature control process and the desulfurization process are repeated when sulfur is to be released from the emission control device.

摘要： In an internal combustion engine, a sulfur detection sample gas is generated in a sample gas generation chamber by fuel of an amount smaller than the amount of fuel fed to a combustion chamber and proportional to the amount of fuel fed to the combustion chamber. An SOx sensor having a sensor part trapping the sulfur contained in the sample gas and capable of detecting the amount of sulfur trapped in the sensor part from the property changes of the sensor part is provided. The amount of SOx that flows into the catalyst is estimated from the output value-of this SOx sensor.
