ABSTRACT:
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.
