    Abstract: A NOx occluding member that occludes NOx when the air-fuel ratio is on the fuel-lean side is disposed in an engine exhaust passage. An NOx ammonia sensor is disposed in the engine exhaust passage downstream of the NOx occluding member. A surplus amount of a reducing agent that is not used to release NOx is determined from a change in the ammonia concentration detected by the NOx ammonia sensor when the air-fuel ratio is changed to the fuel-rich side so as to release the NOx from the NOx occluding member.

    Abstract: An exhaust gas purifying apparatus for an internal combustion engine includes plural catalysts provided in parallel. In a case where temperatures of the catalysts need to be raised, a catalyst is selected from among the catalysts and the exhaust gas is allowed to flow in the selected catalyst. In addition, the temperature of the selected catalyst is raised without using a reducing agent when the temperatures of the catalysts are lower than a temperature range in which the reducing agent can be purified. Alternatively, the reducing agent is supplied to the selected catalyst so as to raise the temperature thereof when the temperatures of the catalysts are equal to or higher than the temperature at which the reducing agent can be purified.

    Abstract: A method and system for controlling the operation of an internal combustion engine, wherein exhaust gas generated by the engine is directed through an emission control device, includes determining instantaneous rates of storage for a constituent of the exhaust gas, such as NOx, as well as the capacity reduction of the device to store the exhaust gas constituent as a function of a calculated value representing an amount of SOx which has accumulated in the device since a prior device-regeneration (desulfation) event. The calculated accumulated SOx value is also preferably used to schedule a device-regeneration event, as when the calculated accumulated SOx value exceeds a predetermined threshold value.

    Abstract: In an exhaust path, a HC trapping material which traps HC contained in exhaust gas temporarily, a H2O trap which traps H2O contained in exhaust gas and a CO oxidation catalyst are arranged in this order from the upstream side, wherein the H2O trap is disposed just upstream of and close to the CO oxidation catalyst. H2O and HC which are components disturbing the activity of the CO oxidation catalyst can be removed efficiently and the adsorption heat and condensation heat of H2O can be efficiently utilized to raise the temperature of the CO oxidation catalyst so that early activation of the CO oxidation catalyst is accomplished just after an engine starts.
