    摘要： A temperature sensor is provided in an exhaust passage in an internal combustion engine. A delay in a response from the temperature sensor is compensated for. A change rate (ΔTs) is sequentially calculated which is an amount of change in a detected value from the temperature sensor per predetermined time. The calculated change rate is multiplied by a predetermined characteristic value to calculate a correction value. The predetermined characteristic value reflects a relationship between a sensor response delay induced temperature detection error (ERROR) and the change rate. The detected value is corrected based on the calculated correction value, thus calculating the temperature of the exhaust gas serving as a measured value.

    摘要： This exhaust purification system 1 is provided with: a fuel injection amount acquisition unit 11 for acquiring fuel injection amounts of a vehicle; a temperature acquisition unit 12 for acquiring the temperature of a catalyst for reducing and purifying nitrogen compounds in exhaust; a temperature control unit 13 for controlling the temperature of the catalyst; and an execution control unit 14 which causes the temperature control unit 13 to increase the temperature of the catalyst when the temperature of the catalyst is lower than a prescribed threshold and the fuel injection amount satisfies a prescribed condition.

    摘要： A fluid treatment system comprises a housing defining a fluid flow channel through which fluid is flowable in a fluid flow direction from an inlet to an outlet of the housing, a first fluid treatment device positioned within the fluid flow channel between the inlet and outlet, a second fluid treatment device positioned within the fluid flow channel between the first fluid treatment device and the outlet, and at least one sensor module comprising a sensor probe positioned within the fluid flow channel between the first and second fluid treatment devices. The sensor probe comprises a plurality of hollow arms extending radially outward from a radially inward portion to a radially outward portion of the fluid flow channel. Each of the arms comprises apertures facing a direction substantially opposite the fluid flow direction, the apertures being in fluid receiving communication with a sample portion of fluid flowing through the fluid flow channel. The sensor module further comprises at least one sensor communicable in sensing communication with fluid received through the apertures.
