摘要： When a temperature increasing process is performed, a CPU sets a target temperature of a catalyst to be lower when a coolant temperature is low than when the coolant temperature is high. The CPU decreases an increase coefficient of fuel in the temperature increasing process when a value obtained by subtracting an estimated value of a temperature of the catalyst from the target temperature is equal to or less than a first prescribed value.

摘要： An exhaust gas treatment assembly for an exhaust gas system of an internal combustion engine includes a housing defining a longitudinal axis. A first exhaust gas treatment unit is inserted in the housing and has a first casing and at least one first exhaust gas treatment unit carried in the first casing. A second exhaust gas treatment unit is inserted in the housing and has a second casing and at least one second exhaust gas treatment unit carried therein. A locking arrangement is for locking a first exhaust gas treatment unit in the housing at least against movement in the direction of the longitudinal axis in a locked state, wherein, when the first exhaust gas treatment unit and the second exhaust gas treatment unit are inserted in the housing, the locking arrangement is blocked in the locked state by the second exhaust gas treatment unit.

摘要： A sampling assembly for an exhaust gas aftertreatment system includes a body layer, an outer bowl, a first sampler, and an inner bowl. The body layer defines a cylindrical passage. The outer bowl is coupled to the body layer. The first sampler extends circumferentially along the body layer to the outer bowl. The first sampler includes a first sampler channel and a first sampler aperture. The first sampler channel is configured to provide exhaust gas into the outer bowl. The first sampler aperture is configured to receive the exhaust gas from the cylindrical passage and provide the exhaust gas into the first sampler channel. The inner bowl is disposed at least partially within the outer bowl and configured to receive the exhaust gas from the outer bowl and provide the exhaust gas into the cylindrical passage.
