摘要： A soot sensor for the detection of soot particles in an exhaust gas flow, having interdigitally engaged measurement electrodes applied on a substrate. An electrical resistance between the measurement electrodes is a measure of soot load of the exhaust gas flow. The measurement electrodes are divided into two regions, a first region in which no soot particles can be deposited and a second region where soot particles are deposited from the exhaust gas flow. The first region and the second region are exposed simultaneously to the other conditions prevailing in the exhaust gas flow.

摘要： A tank ventilation system having an intake tract, the tank ventilation system including a hydrocarbon reservoir, a sensor, and a valve. The valve and the sensor are arranged in a fluid line that couples the hydrocarbon reservoir to the intake tract. The sensor captures a hydrocarbon concentration of a fluid in the fluid line. A captured value of the hydrocarbon concentration is measured using the sensor. When the open valve, a mass flow of the fluid flowing through the fluid line into the intake tract is captured or determined. An air/fuel ratio of an air/fuel mixture fed to the internal combustion engine is determined. An estimated value of the hydrocarbon concentration in the fluid line is determined according to the mass flow of the fluid and the air/fuel ratio. The sensor is calibrated according to the captured value of the hydrocarbon concentration and the estimated value of the hydrocarbon concentration.
