    摘要： A system and method including a radially non-uniformly plugged flow-through honeycomb substrate positioned upstream of a wall-flow particulate filter for controlled thermal regeneration of the wall-flow particulate filter. The flow-through honeycomb substrate has an inlet face and an outlet face and a plurality of longitudinal walls extending between the inlet face and the outlet face. The longitudinal walls define a plurality of parallel channels extending between the inlet face and the outlet face. The honeycomb substrate has a flow-through region including a first portion of the parallel channels and a flow-control region including a second portion of the parallel channels. The first portion of the parallel channels includes unplugged channels and the second portion of the parallel channels includes plugged channels. The flow-control region adjusts flow distribution through the substrate such that flow having a first flow distribution received at the inlet face emerges at the outlet face with a second flow distribution, different than the first flow distribution.

    摘要： A system for measuring the non-methane HC concentration of gas sample, e.g. automotive exhaust gas, comprising first and second catalytic differential calorimetric sensors. The first catalytic differential calorimetric sensor is capable of producing a first output signal representative of the exothermic effect of the oxidation of the predominate oxidizable species (CO+H.sub.2 +non-methane HC combination) in the gas sample. The second catalytic differential calorimetric sensor is capable of producing a second output signal representative of the exothermic effect of the combined oxidation of the CO+H.sub.2 +alkene hydrocarbon species in the gas sample. Lastly, the system includes a means for comparing the first output signal with the second output signal, thereby indicating the total concentration of unburned aromatic and alkane hydrocarbon species in the gas sample which directly correlates to the total non-methane HC concentration. A method carried out by the system comprises the following steps: (a) contacting a first portion of an exhaust gas with a sensor and producing an output signal representative of the concentration of the predominate (CO+H.sub.2 +non-methane HC species) oxidizable species in the exhaust gas; (b) contacting a second portion of the exhaust gas with a second sensor and producing a second output signal representative of the combined concentration of CO+H.sub.2 +alkene hydrocarbon species in the second exhaust gas portion; and (c) determining the aromatic and alkane hydrocarbon species concentration, and thus the total non-methane HC concentration, of the exhaust gas by comparing the first output signal with the second output signal.
