    摘要： In a diesel engine exhaust system a plurality of valved ceramic filters are connected in parallel in the exhaust stream and loaded sequentially. While one filter is preferentially loaded, a second filter is opened to the exhaust stream when backpressure reaches a predetermined value. The secondary filter is removed from the exhaust stream when air flow to the engine drops a discrete amount below a peak air flow determined by the backpressure which would cause the secondary filter to be placed in the exhaust stream. The preferentially loaded filter is bypassed when completely loaded and regenerated. The secondary filter is then preferentially loaded and the sequence continues.

    摘要： A sensor device having mechanisms for obtaining air mass flow rate into the engine, pressure drop across the filter, and adsolute temperature near the inlet end of the filter to calculate a factor proportional to pressure drop and inversely proportional to air mass flow rate and absolute temperature, all of which are raised to powers determined from empirical data for a particular system. When the calculated factor k exceeds a predermined value, system regeneration is initiated. The sensor mechanism and method is indpendent of engine exhaust flow, engine speed, and exhaust temperature.
