Abstract

In an exhaust passage, a pressure detection means is provided on the upstream side of a filter, and an exhaust throttle valve is provided on the downstream side of the filter. And, when the operational state of the internal combustion engine is a steady operational state (in a step S101), the opening amount of an exhaust throttle valve is controlled so that the upstream pressure detected by the pressure detection means becomes a constant value (in a step S103).
