Conductance G for several soot deposition cycles at UIDE = 40 V during constant engine operation. After regeneration, an additional small power was applied to the sensor to establish a slightly higher temperature of the sensor tip compared to the exhaust temperature. This temperature difference dT = TsensorTexhaust that was kept constant during each soot deposition phase.
